Many Michigan homeowners assume pest control is a warm-weather service. This is one of the most common misconceptions BTR Pest Control addresses every year. Winter pest pressure in Metro Detroit is different from summer pressure, but it is not lower. Mice and rats that moved indoors in October are breeding inside walls and attics from December through March. Overwintering insects tucked into wall voids crawl into living spaces during January and February warm snaps. Bed bugs spread most aggressively in winter because infested apartments share heating systems with neighbors. This guide explains what to watch for and why year-round service is worth the cost.
Rodents Breed All Winter
House mice do not hibernate. Norway rats do not hibernate. Both species reach peak reproduction rates in winter because they are inside warm structures with unlimited food from pet bowls, bird feeders, pantries, and kitchen crumbs. A pair of mice that entered a Michigan home in October can produce 40 offspring by February. Signs that rodents are active in a home include droppings in the garage, pantry, or basement; greasy rub marks along baseboards and pipe runs; scratching sounds in the attic between midnight and 4 AM; chewed food packaging; and urine stains under refrigerators and stoves. BTR winter rodent service combines interior trapping, exterior exclusion sealing, and attic rodent inspection.
Overwintering Insects Wake in Warm Spells
Stink bugs, box elder bugs, ladybugs, cluster flies, and occasional wasp queens spend Michigan winter in attics, wall voids, and soffits. When a February thaw pushes daytime temperatures into the 50s, these insects become active and often end up on interior windowsills, kitchen counters, and ceiling light fixtures. Vacuuming is the best homeowner response. BTR applies targeted attic and wall-void treatments to kill the overwintering population before spring emergence.
Bed Bug Apartment Spread
Bed bugs in multi-unit apartment buildings move between units through shared walls, electrical outlets, and heating systems. Winter increases bed bug movement because residents spend more time indoors and because vacancy-turnovers in apartment buildings expose new residents to existing infestations. BTR treats bed bugs year-round and offers apartment-building coordination for property managers.
Carpenter Ants Inside Walls
Carpenter ants in Michigan overwinter inside the parent colony, usually in wet wood associated with roof leaks, deck ledger boards, or bathroom plumbing. Homeowners who see large black ants in kitchens or bathrooms during January or February almost always have an active colony inside the structure — outdoor ants cannot survive Michigan winter. Winter is an excellent time to eliminate the colony because all workers and the queen are reachable in a single treatment.
Year-Round BTR Service Plans
BTR quarterly service plans include winter treatment at no discount or penalty because the work remains valuable. Customers on monthly or quarterly plans receive free retreatment between scheduled visits if pests return. Call (734) 338-1828 to schedule winter service.

Frequently Asked Questions
Do exterminators work in winter?
Yes. BTR Pest Control operates daily 9 AM to 8 PM year-round. Winter service focuses on interior work, attic inspections, and targeted exterior treatments on milder days.
Why do I see ants in my kitchen in January?
Ants inside Michigan homes in winter almost always come from a colony located within the structure itself — usually associated with a moisture source. BTR can locate the source and eliminate the colony in a single visit.
How do I get rid of mice in my attic?
Schedule BTR attic rodent service. Treatment combines interior trapping, attic inspection and sealing, and exterior exclusion to prevent new entries. DIY traps alone rarely resolve active attic populations.
Are winter pest products safe indoors?
Yes. BTR uses the same EPA-approved products year-round, applied according to label requirements. Products are safe for families and pets when dry.
Can I cancel winter service on my pest plan?
BTR quarterly and monthly plan customers can skip a winter service if they prefer, but we recommend against it. Winter service addresses rodent breeding, carpenter ant colonies, and overwintering insect populations that all compound if left untreated.
