Restaurant Pest Control in Milwaukee: What Every Food Service Business Needs to Know

A little girl sits at the counter of a restaurant eating out of a red basket.

If you operate a food service business, restaurant pest control in Milwaukee isn’t optional — it’s a compliance requirement, a liability concern, and a direct threat to your reputation if it goes wrong. One failed health inspection, one online review mentioning a cockroach, or one rodent spotted by a customer can do damage that takes months to undo.

Here’s what Milwaukee restaurant owners and food service operators need to know about pest control, what the requirements actually look like, and how to make sure you’re protected.

Why Restaurants Are High-Risk Pest Environments

Food service businesses create ideal conditions for pests. Warmth, moisture, food debris, and constant deliveries coming in and out of your building combine to make restaurants one of the most pest-prone commercial environments there is.

The pests most commonly affecting Milwaukee restaurants include:

  • Cockroaches — drawn to warm, humid kitchen environments with food residue. German cockroaches in particular thrive in commercial kitchens and reproduce fast enough to become a serious problem within weeks.
  • Rodents — mice and rats follow food sources and can enter through gaps as small as a dime. Delivery entrances, floor drains, and utility penetrations are common access points.
  • Flies — drain flies, fruit flies, and house flies are persistent in food service environments and are a direct food contamination risk.
  • Stored product pests — pantry pests like Indian meal moths and grain beetles move in through deliveries and infest dry storage quickly if not caught early.

None of these problems resolve on their own, and in a restaurant environment, any delay in treatment carries real consequences.

Restaurant Pest Control Milwaukee: What Compliance Actually Requires

Wisconsin food service establishments are subject to inspection by the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) as well as local health departments. Pest activity is one of the most heavily weighted categories in a food service inspection.

What inspectors look for includes:

  • Evidence of rodent or insect activity, including droppings, gnaw marks, and live or dead pests
  • Gaps or openings in the structure that allow pest entry
  • Improper food storage that creates harborage conditions
  • Documentation of pest control service and treatment records

Working with a licensed, professional food service exterminator in Milwaukee means you have documented treatment records on file, which inspectors expect to see. A reputable pest control company will provide service documentation after every visit.

What Professional Restaurant Pest Control Looks Like

Commercial pest control for food service businesses is more involved than a standard residential treatment. Here’s what a professional program should include:

Scheduled preventative service. Reactive treatment after a pest problem appears is the wrong approach for a restaurant. A proactive service schedule, typically monthly or bi-monthly, catches problems before they escalate and keeps your facility in a defensible compliance position.

Thorough inspection of high-risk areas. Kitchen equipment, floor drains, dry storage, delivery areas, dumpster enclosures, and utility rooms all require regular attention. These are the areas where pest activity originates and where inspectors look first.

Targeted, food-safe treatment methods. Treatment in a food service environment requires products and methods that are safe for use around food preparation areas. Gel baits, tamper-resistant rodent stations, and insect light traps are standard tools in a commercial food service pest program.

Service documentation. Every visit should produce a written report documenting what was found, what was treated, and any recommendations for structural or sanitation improvements. This documentation protects you during inspections.

If your facility receives a pest-related violation, act immediately. Contact a licensed pest control company the same day, document every step of your response, and be prepared to demonstrate corrective action to your inspector. Speed and documentation are your two most important assets in this situation.

The better approach, of course, is making sure you never get there. A consistent, professional pest control program is significantly less expensive than the cost of a failed inspection, a temporary closure, or the reputational damage that follows.

Frequently Asked Questions

Do Milwaukee restaurants have to have a pest control contract? There’s no specific law requiring a contract, but documented pest control service is expected by inspectors and is effectively required to maintain compliance. A regular service program with written records is the standard.

Can pest control be done while the restaurant is open? It depends on the treatment type and the area being treated. Many exterior and non-food-contact treatments can be done during operating hours. Kitchen and food preparation area treatments are typically scheduled before opening or after closing. Your technician will work around your schedule.

How often should a Milwaukee restaurant be treated for pests? Most food service establishments benefit from monthly service, with some high-volume or higher-risk operations requiring bi-monthly visits. Your pest control provider should assess your facility and recommend a frequency based on your specific risk factors.

What pests are most common in Milwaukee restaurants? German cockroaches, mice, drain flies, fruit flies, and stored product pests are the most frequent issues in Milwaukee food service environments. All are manageable with a consistent professional pest control program.

Property Management Pest Control in Wisconsin: What Landlords and PMs Need to Know

If you manage rental properties in Wisconsin, property management pest control isn’t a line item you can afford to treat as optional. Pest problems in rental units create tenant complaints, lease disputes, potential legal liability, and in some cases habitability violations that put your rental license at risk. Getting ahead of pest issues rather than reacting to them is one of the most cost-effective decisions a property manager or landlord can make.

Here’s what Wisconsin landlords and property managers need to know about their pest control obligations, how to structure a program that protects your properties and your tenants, and when to call a professional.

Managing rental properties in Milwaukee or Southeastern Wisconsin? Talk to our experienced commercial team about a property management pest control program.

Wisconsin Landlord Pest Control Obligations: What the Law Actually Says

Wisconsin law requires landlords to maintain rental properties in a condition that is fit for human habitation. Pest infestations that affect habitability, including rodents, cockroaches, and bed bugs, fall squarely within this obligation.

Under Wisconsin Administrative Code ATCP 134, landlords are required to:

  • Maintain rental units free from conditions that are dangerous to tenant health or safety
  • Respond promptly to tenant-reported pest problems
  • Disclose known pest issues to prospective tenants before lease signing

Failure to address a reported pest problem within a reasonable timeframe can give tenants grounds to withhold rent, terminate their lease, or pursue legal action. In multi-unit properties, an unaddressed infestation in one unit that spreads to others significantly compounds your liability exposure.

Understanding your obligations before a tenant complaint arrives is significantly better than learning them during a dispute.

The Pest Problems Most Common in Wisconsin Rental Properties

Mice and rodents are the most frequently reported pest issue in Milwaukee rental properties, particularly in older buildings with aging foundations and utility penetrations that haven’t been sealed. Fall and winter drive rodents indoors, and in multi-unit buildings they move freely between units through shared wall voids and plumbing chases.

Bed bugs are a persistent challenge in multi-unit residential properties. They spread between units, tenants dispute responsibility for the source, and treatment in one unit without addressing adjacent units frequently results in reinfestation. Landlord pest control in Milwaukee for bed bugs requires a clear protocol and consistent follow-through.

Cockroaches are most common in older urban rental stock, particularly in properties with shared plumbing and aging kitchen infrastructure. German cockroaches move between units rapidly and are extremely difficult to eliminate without treating an entire building section simultaneously.

Ants and seasonal pests generate consistent tenant complaints in spring and summer, particularly in ground-floor units and properties with mature landscaping close to the building foundation.

Why Reactive Pest Control Costs More Than Preventative Service

This is the calculation most property managers eventually make after dealing with a significant infestation: the cost of reactive treatment for an established pest problem, combined with tenant relations damage, potential legal exposure, and unit downtime, almost always exceeds the cost of a consistent preventative program.

A proactive property management pest control program in Wisconsin typically includes:

  • Scheduled perimeter treatments at exterior entry points, foundation lines, and common areas on a seasonal or monthly basis
  • Unit inspections at tenant turnover to identify and address pest activity before a new tenant moves in
  • Rapid response protocols for tenant-reported pest issues that keep response times short and documentation thorough
  • Service records for every treatment, which protect you in the event of a tenant dispute or habitability complaint

How to Structure Pest Control Across a Multi-Unit Property

Single-family rental properties are relatively straightforward. Multi-unit properties require a more structured approach.

For apartment buildings and multi-unit residential properties, a building-wide treatment program is more effective and more cost-efficient than treating individual units reactively. Treating one cockroach-infested unit while leaving adjacent units untreated almost guarantees reinfestation within weeks. A professional commercial exterminator in Milwaukee can assess your building and recommend a program that addresses the property as a whole rather than as a collection of isolated units.

For larger portfolios across multiple properties, a consolidated service agreement with a single provider gives you consistent documentation, predictable costs, and a technician who knows your properties and their specific pest pressure points.

Protect Your Properties Before a Tenant Complaint Forces Your Hand

Pest problems in rental properties don’t stay contained. They spread between units, generate complaints, and create liability that a consistent professional program would have prevented entirely.

Ehlers Pest Management works with property managers and landlords across Milwaukee and Southeastern Wisconsin to build pest control programs that protect tenants, satisfy Wisconsin habitability requirements, and keep your properties running without the disruption of reactive emergency treatments.

Frequently Asked Questions

Who is responsible for pest control in a Wisconsin rental — the landlord or the tenant? In Wisconsin, the landlord is generally responsible for maintaining the property free from pest infestations that affect habitability. Tenant-caused infestations, such as those resulting from unsanitary conditions the tenant created, may shift some responsibility, but the landlord is still typically obligated to address the infestation itself. Consulting with a Wisconsin attorney familiar with landlord-tenant law is advisable for specific situations.

Can a tenant withhold rent for a pest problem in Wisconsin? Wisconsin law provides tenants with remedies for landlord failure to maintain habitable conditions, which can include pest infestations. Tenants may have grounds to withhold rent or pursue other legal remedies if a landlord fails to respond to a reported pest problem within a reasonable timeframe. Prompt response and documentation are your best protection.

How quickly should a landlord respond to a tenant pest complaint in Wisconsin? While Wisconsin law doesn’t specify an exact timeframe, responding within 24 to 48 hours and scheduling professional treatment within a week of a reported infestation is considered reasonable practice. Delays beyond that window increase your liability exposure and give tenants stronger grounds for legal remedies.

How do I handle bed bugs in a multi-unit rental property? Bed bug treatment in a multi-unit property should include the affected unit and all directly adjacent units, including units above, below, and to either side. Treating a single unit in isolation almost always results in reinfestation from neighboring units. A professional assessment of the full affected area is essential before treatment begins.

What pest control documentation should I keep as a Wisconsin landlord? Retain service reports from every pest control treatment, tenant communications related to pest complaints, and any inspection reports that document pest findings or conditions. This documentation protects you in the event of a habitability dispute and demonstrates good-faith compliance with your obligations.

Mice in the House This Winter? Wisconsin Rodent Season Explained

Two mice press their faces up close to a camera

If you haven’t dealt with mice in your Wisconsin home yet, summer is actually the best time to think about it — because by the time fall arrives and rodents start pushing indoors, the window to get ahead of the problem has already closed. Understanding how and why mice in Wisconsin homes become a seasonal problem gives you a meaningful advantage before rodent season starts.

Here’s what drives rodent activity in Southeastern Wisconsin, which homes are most vulnerable, and what to do now while the timing is still on your side.

Why Wisconsin Homes See More Mice in Fall and Winter

Mice don’t hibernate. When outdoor temperatures drop in Wisconsin, they look for somewhere warm, dry, and close to food. Your home checks every one of those boxes.

Rodent pressure on Wisconsin homes typically increases starting in September and peaks through November as temperatures fall consistently. Mice that are going to overwinter indoors don’t wait for the first frost — they begin scouting for entry points in late summer, which means the decisions you make now in June and July directly affect what you find in your walls come October.

A few factors specific to Southeastern Wisconsin make rodent pressure more pronounced here than in warmer climates:

  • Temperature extremes. Wisconsin winters are cold enough to make outdoor survival genuinely difficult for small mammals, which increases the drive to find indoor shelter earlier in the season.
  • Older housing stock. Milwaukee and its surrounding communities have a significant proportion of older homes with aging foundations, deteriorating weatherstripping, and utility penetrations that were never properly sealed. These homes offer mice multiple entry points that newer construction typically doesn’t.
  • Mature landscaping and wooded lots. Overgrown vegetation, wood piles, and mature tree coverage close to the home provide harborage and travel corridors that bring mice right to your foundation.

What Mice Are Doing Right Now in Summer

Summer is actually an active period for the mouse populations that will eventually target your home. Mice reproduce rapidly during warmer months — a single female can produce multiple litters between spring and fall, each with several pups that reach reproductive maturity within weeks.

What this means practically is that the mouse population in your yard and neighborhood is at or near its seasonal peak right now. Those populations will begin moving indoors as temperatures drop. The larger the outdoor population heading into fall, the more pressure your home will face at the entry points you haven’t yet addressed.

Summer is also when exclusion work is most comfortable and most effective to complete. Sealing foundation gaps, replacing weatherstripping, and addressing utility penetrations is work that’s far easier to do in warm weather than during a Wisconsin winter.

Signs That Mice Have Already Found a Way In

Even in summer, some homes already have rodent activity. Signs worth looking for include:

  • Droppings near baseboards, in cabinets, behind appliances, or in utility areas
  • Gnaw marks on food packaging, wood near the floor, or electrical wiring
  • Nesting material in undisturbed storage areas, deep cabinets, or boxes that haven’t been moved recently
  • A musty odor in enclosed spaces like utility rooms, closets, or crawl spaces
  • Pet behavior changes — dogs and cats frequently detect rodent activity before their owners do

Finding any of these signs in summer means an entry point exists and is already being used. Addressing it now prevents a much larger fall infestation.

Why Getting Ahead of Rodent Season Matters

This is the calculation that makes summer rodent control in Milwaukee worthwhile. Mice that enter your home in fall have all winter to establish nesting sites, reproduce, and cause damage inside wall voids, insulation, and around electrical wiring before warmer weather drives them back out.

An established winter infestation is significantly harder and more expensive to resolve than entry points identified and sealed before rodents move in. Reactive rodent control in Milwaukee after mice are already inside involves locating nesting sites, eliminating the existing population, and then completing the exclusion work that should have happened in fall. Doing it in the right order — exclusion first, while populations are still outdoors — is faster, less disruptive, and less costly.

What to Do Now to Protect Your Home This Fall

A few targeted steps taken this summer meaningfully reduce your rodent risk heading into fall:

  • Inspect your foundation for gaps, cracks, and utility penetrations larger than a dime — the minimum opening a mouse needs to enter
  • Check weatherstripping around all exterior doors and replace anything that’s compressed, torn, or leaving a visible gap at the bottom
  • Move wood piles and dense vegetation away from the foundation to eliminate harborage close to your home
  • Schedule a professional inspection if you’ve had rodent problems in previous fall or winter seasons — a technician can identify entry points you’re likely to miss and assess your home’s specific vulnerability

Frequently Asked Questions

When does rodent season start in Wisconsin? Mice begin scouting for indoor entry points in late summer, with pressure on Wisconsin homes increasing noticeably in September and peaking through November. Summer is the ideal window to address entry points and vulnerabilities before this seasonal push begins.

How do mice get into Wisconsin homes? Mice can squeeze through gaps as small as a dime. Common entry points include gaps around utility pipes and conduits, deteriorating weatherstripping around doors and windows, cracks in the foundation, and openings around dryer vents and HVAC penetrations. Older homes with aging building envelopes are particularly vulnerable.

Can mice cause damage beyond the nuisance? Yes. Mice gnaw on electrical wiring, which is a documented cause of house fires. They also damage insulation, contaminate food storage areas with droppings and urine, and can carry pathogens including salmonella. The structural and health risks from an established rodent infestation are significant enough to warrant prevention rather than reaction.

Is summer a good time to treat for rodents if I haven’t seen any signs yet? Yes. A summer inspection and exclusion treatment addresses entry points while outdoor populations are still outside, which is significantly more effective than treating an established infestation after mice have already moved in for the winter.

Box Elder Bugs in Wisconsin: Why They Show Up Every Year and How to Stop Them

Box elder bugs gather in a window sill corner.

If you’ve lived in Wisconsin for more than a season or two, you already know box elder bugs. They show up on the sunny sides of homes every fall, pile up on warm exterior walls, and find their way inside through gaps and cracks before temperatures drop. Box elder bugs in Wisconsin are one of the most predictable pest problems homeowners deal with — and one of the most frustrating, because they come back year after year no matter what you do.

Here’s why that happens, what’s actually drawing them to your home, and what you can do to reduce the problem before it starts.

What Box Elder Bugs Actually Are

Box elder bugs are black and red insects about half an inch long, recognizable by the distinctive red markings along their wings and sides. They feed primarily on the seeds of box elder trees, which are extremely common across Southeastern Wisconsin, as well as maple and ash trees.

They don’t bite, they don’t cause structural damage, and they don’t reproduce indoors. What they do is aggregate in large numbers, stain light-colored surfaces with their excrement, and release an unpleasant odor when crushed. For most homeowners, the problem is sheer volume — a few box elder bugs are a minor annoyance, but hundreds clustering on your siding and working their way into your walls is a different situation entirely.

Why Box Elder Bugs Keep Coming Back to Your Home

This is the question most Wisconsin homeowners ask after dealing with box elder bugs for multiple seasons. The answer comes down to two things: proximity to host trees and your home’s sun exposure.

Box elder bugs spend summer feeding and reproducing in nearby trees. As temperatures drop in fall, they seek warmth and shelter for overwintering — and the sunny, south and west-facing exterior walls of your home are exactly what they’re looking for. Once a population establishes your home as a reliable overwintering site, they return to it year after year. They don’t need to find it again — they already know it’s there.

If you have box elder, maple, or ash trees on or near your property, you’re going to see box elder bugs. The question is how many, and whether they’re getting inside.

When to Expect Box Elder Bug Activity in Wisconsin

Box elder bug activity in Wisconsin follows a consistent seasonal pattern:

  • Spring — overwintering adults emerge from wall voids and sheltered areas as temperatures warm. You’ll see them on exterior walls and around windows as they work their way back outside.
  • Summer — adults disperse to host trees to feed and reproduce. Activity around your home decreases significantly during this period.
  • Late summer through fall — new generation adults begin aggregating on warm exterior surfaces, particularly south and west-facing walls, in preparation for overwintering. This is peak nuisance season and the most important window for treatment and exclusion.

What Actually Works Against Box Elder Bugs

Managing box elder bugs in Wisconsin requires a combination of exclusion and treatment. Neither approach alone is fully effective.

Exclusion first. Sealing gaps around windows, doors, utility penetrations, and foundation cracks prevents box elder bugs from entering wall voids to overwinter. This is the single most impactful long-term measure you can take. Caulk, weatherstripping, and door sweeps applied before fall aggregation begins make a measurable difference.

Exterior perimeter treatment. A professional residual treatment applied to exterior walls, foundation, and entry points in late summer or early fall, before aggregation peaks, significantly reduces the number of bugs that make it inside. Timing matters — treatment applied after large numbers have already entered is far less effective.

Vacuuming interior populations. For bugs that have already made it inside, vacuuming is the most practical removal method. Crushing them releases an odor and can cause staining, so direct contact removal is best avoided.

Removing host trees is sometimes suggested but rarely practical. Box elder trees are widespread across Southeastern Wisconsin, and removing trees on your own property doesn’t eliminate the source population from neighboring properties.

When to Call a Box Elder Bug Exterminator in Milwaukee

If you’re seeing large numbers of box elder bugs on your exterior walls or finding them consistently inside your home, a professional exterior treatment is the most effective solution. A licensed box elder bug exterminator in Milwaukee can apply a targeted perimeter treatment at the right time and in the right concentration to significantly reduce overwintering populations before they become an indoor problem.

If box elder bugs have been a recurring issue on your property, a seasonal treatment program that includes fall perimeter service is the most practical long-term approach.

Frequently Asked Questions

Why are there so many box elder bugs on my house in Wisconsin? Your home’s sun exposure and proximity to box elder, maple, or ash trees are the two biggest factors. South and west-facing walls absorb the most heat in fall, making them attractive aggregation sites. If you have host trees nearby, consistent annual activity is normal.

Do box elder bugs cause damage to my home? Box elder bugs don’t cause structural damage and don’t reproduce indoors. Their primary impacts are cosmetic — staining on light surfaces from excrement — and the general nuisance of large numbers inside the home. In significant numbers inside wall voids, they can attract other pests that feed on them.

When is the best time to treat for box elder bugs in Wisconsin? Late summer through early fall, before large numbers begin aggregating on exterior walls, is the most effective treatment window. Treating after aggregation has peaked is less effective and doesn’t address bugs already inside wall voids.

Can I spray box elder bugs myself? Over-the-counter sprays can kill bugs on contact but don’t provide the residual effectiveness of professional products and are difficult to apply at the coverage levels needed for a full exterior perimeter treatment. For significant infestations, professional treatment delivers meaningfully better results.

Ants in Your House This Spring? Here’s Why It’s Happening in Milwaukee

An image of a colony of ants gathering in the corner of a residential home.

If you’re seeing ants in your house this spring in Milwaukee, you’re not imagining a surge — it’s real, it’s predictable, and it’s happening in homes across Southeastern Wisconsin right now. Spring is the most active season for ant activity indoors, and understanding why helps you respond more effectively than reaching for a can of spray and hoping for the best.

Here’s what’s driving spring ant activity in Milwaukee homes, why it tends to get worse before it gets better, and what to do about it.

Why Spring Triggers Ant Activity in Milwaukee Homes

Winter doesn’t kill ant colonies in Wisconsin — it slows them down. Colonies overwinter in a dormant state deep in the soil, under foundations, or inside wall voids where temperatures stay stable. When spring arrives and ground temperatures begin rising, colonies wake up hungry, crowded, and ready to expand.

Several things happen at once during a Wisconsin spring that drive ants indoors:

  • Colony expansion. Queens begin laying eggs again as temperatures rise, and colonies grow rapidly. More mouths to feed means more foragers searching for food sources, including inside your home.
  • Heavy spring rainfall. Rain saturates soil and drives ants to higher, drier ground. Your foundation and the warm, dry interior of your home are exactly what a flooded colony is looking for.
  • Increased foraging range. Warmer temperatures increase ant metabolic activity, meaning foragers travel further and more frequently than they did in cooler months.

The result is that ant activity can appear to come from nowhere in spring — one week your kitchen is clear, the next you have a trail moving across your counter. That’s not a new problem appearing. That’s a colony that was already nearby waking up and expanding its range.

Spring Ant Control Milwaukee: What You’re Most Likely Dealing With

Two species account for the majority of spring ant problems in Milwaukee homes:

Pavement ants are small, dark brown ants commonly found near foundations, under slabs, and along baseboards. They’re most active in spring and early summer and are among the first species to show up indoors after winter. Pavement ant colonies can number in the tens of thousands and establish foraging trails quickly once temperatures warm.

Odorous house ants are slightly smaller, darker, and emit a distinctive blue-cheese odor when crushed. They’re highly adaptable, nest in a wide range of locations including wall voids and under flooring, and are particularly persistent once established indoors. Spring ant control in Milwaukee frequently involves odorous house ants because of how readily they exploit new food sources.

Both species respond differently to treatment, which is one of the most important reasons accurate identification matters before any product is applied.

What Makes Spring Ant Problems Worse

A few common homeowner responses to spring ant activity tend to make the problem harder to resolve:

Spraying contact insecticide. It kills foragers on contact but doesn’t reach the colony. Worse, some ant species respond to contact spray by budding — splitting into multiple satellite colonies that spread the infestation further into your home. If you’ve sprayed and the problem came back within days, this is likely what happened.

Treating too late. By the time you’re seeing a consistent trail of ants indoors, the colony is already well established and has been foraging your home long enough to reinforce its chemical trail repeatedly. Earlier intervention is always more effective and less costly.

Focusing on the interior only. Ants entering your home are coming from somewhere outside. Treating only inside your home addresses symptoms without touching the source.

What to Do About Spring Ants in Your Milwaukee Home

If you’re seeing consistent ant activity indoors this spring, here’s the most effective approach:

  • Don’t spray. Bait is more effective because foragers carry it back to the colony.
  • Eliminate moisture sources and food attractants that are drawing foragers inside.
  • Seal visible entry points around pipes, windows, and foundation gaps.
  • Contact a professional for species identification and targeted treatment if activity persists beyond a week or two, if you’ve tried DIY treatment without success, or if you’re seeing ants in multiple areas of your home.

Spring ant problems are very manageable when addressed early and correctly. Waiting to see if they go away on their own is rarely a strategy that works.

Frequently Asked Questions

Why do I get ants every spring in my Milwaukee home? If your home has had ant activity in previous springs, it’s likely that a colony is established nearby and has already identified your home as a reliable food source. Colonies return to successful foraging sites year after year. A preventative treatment applied in early spring before foraging activity peaks is the most effective way to break this cycle.

Are spring ants different from ants I see in summer? The same species are typically active through spring and summer, but spring activity tends to be more intense because colonies are expanding rapidly after winter dormancy and foraging aggressively to support that growth. Summer activity usually stabilizes once colonies reach their seasonal population peak.

How do I know if I have a serious ant infestation this spring? Signs of a significant infestation include consistent trails in the same areas, ant activity in multiple rooms, finding ants in food storage areas, or DIY treatments that fail to hold. If any of these apply, professional treatment is the right call.

Is spring the best time to treat for ants in Milwaukee? Early spring, before foraging activity peaks, is actually the ideal window for preventative ant treatment. Treating an active infestation in spring is also very effective because colonies are near the surface and foraging actively, which means bait is picked up and carried back to the colony quickly.
