Every fall, Farmington Hills homeowners face the same problem — mice looking for warmth as Michigan temperatures drop. And every fall, thousands of mice find their way inside because the gaps they use to enter are so small most homeowners never notice them.

A mouse can fit through a hole the size of a dime. A gap around a utility pipe, a crack in the foundation from last winter's freeze-thaw cycle, the space under a garage door that doesn't quite seal — these are the entry points that put mice inside warm Farmington Hills homes every October.

⚠️ Act before October. Prevention steps completed in September — before the cold weather migration begins — are 10x more effective than trying to deal with an established infestation in December. Two mice become 1,500 in a year inside a heated Michigan home.

#1 Seal Every Entry Point Before October

Gaps around utility pipes and foundation cracks are the most common mouse entry points in Farmington Hills homes. Steel wool combined with caulk is the most effective seal — mice cannot chew through steel wool.

This is the single most important step — and the one most homeowners skip because entry points are hard to find. Walk the complete perimeter of your home at ground level and check every one of these locations.

🏗️ Foundation Cracks

Farmington Hills' freeze-thaw cycles create new foundation cracks every winter. Any crack wider than 6mm is a mouse entry point. Seal with concrete patch or expanding foam.

🔧 Utility Pipe Gaps

Gaps around gas lines, water pipes, electrical conduit, and HVAC lines where they enter the foundation. Often left unsealed by builders. Pack with steel wool then seal with caulk.

🚪 Door Weatherstripping

Worn or missing weatherstripping on exterior doors — especially garage entry doors — leaves gaps mice use nightly. Replace any stripping that doesn't form a complete seal.

🏠 Siding Gaps

Where siding meets the foundation, window frames, or corners of the home. Common in Farmington Hills homes built in the 1970s-90s. Seal with exterior-grade caulk.

🌬️ Dryer & HVAC Vents

Exterior dryer vents and HVAC exhaust openings without proper screens. Install fine-mesh screens on all exterior vents — mice will use any unscreened opening.

🌳 Where Deck Meets House

The gap between deck framing and the home's exterior wall is a common and overlooked entry point. Check and seal where deck ledger boards attach to the house foundation.

💡 Best sealing material: Steel wool packed into the gap first, then covered with exterior caulk or expanding foam. Mice cannot chew through steel wool. Foam alone is ineffective — mice chew right through it.

#2 Eliminate All Food Sources and Attractants

Properly sealed food storage containers preventing mice in kitchen pantry — mice prevention Farmington Hills Michigan
Sealed hard-sided food containers eliminate one of the primary reasons mice establish permanent colonies inside Farmington Hills homes. Cardboard and thin plastic bags offer no protection against mice.

Mice enter Farmington Hills homes primarily for warmth — but they stay because of food. Once a mouse finds reliable food sources inside your home, it establishes a permanent colony and brings others. Eliminating food access makes your home significantly less hospitable.

  • Store all pantry items in hard-sided sealed containers — cardboard boxes and thin plastic bags offer no protection
  • Don't leave pet food out overnight — store in sealed metal or hard plastic containers
  • Clean under appliances monthly — crumbs under the stove and refrigerator are a primary food source
  • Empty kitchen trash cans every night — or use trash cans with tight-fitting lids
  • Keep garage trash cans sealed — outdoor food waste near the home draws mice to your property first
  • Clean up fallen fruit, bird seed, and compost near the home — outdoor food sources attract mice to your yard before they find their way inside
  • Don't store grass seed, birdseed, or fertilizer in open bags in the garage
6mm
The size of gap a mouse needs to enter your Farmington Hills home — the width of a pencil. Most homes have dozens of gaps this size or larger.

#3 Protect Your Garage — The #1 Entry Point in Farmington Hills

Garage door bottom seal gap — common mouse entry point in Farmington Hills Michigan homes
The gap under a garage door is one of the most common mouse entry points in Farmington Hills homes. A worn or improperly fitted door seal leaves a gap large enough for mice to enter nightly.

In Farmington Hills attached-garage homes, the garage is where the vast majority of mice enter first — then migrate into the living areas through the interior wall. Most homeowners never connect the garage to the kitchen mouse problem because the path isn't obvious.

  • Replace worn garage door bottom seals — the rubber sweep should form a complete contact with the floor with no gaps
  • Install a door sweep on the interior door between garage and living area
  • Seal all gaps around the interior garage wall where pipes, wires, and HVAC ducts pass through
  • Don't store dog food, bird seed, or grass seed in open bags in the garage
  • Keep the garage clean and clutter-free — piles of boxes, stored furniture, and debris create ideal nesting conditions
  • Check the gap where the garage door track meets the wall at the top corners — mice use this regularly
⚠️ Farmington Hills homeowners: If you have an attached garage and mice in the kitchen, the mice are almost certainly entering through the garage first — not directly through the home exterior. Treat the garage as the primary entry zone.

#4 Fix Landscaping That Invites Mice In

Most Farmington Hills homeowners don't think of landscaping as a mice problem — but the area immediately surrounding your home is where mice live before they come inside. Certain landscaping choices make it dramatically easier for mice to reach your home's entry points undetected.

  • Keep mulch beds at least 12 inches away from the foundation — mulch is warm and provides ideal mouse nesting conditions directly against your home
  • Trim tree branches that overhang or touch the roofline — mice use branches as highways onto your roof and into attic vents
  • Keep firewood stacked at least 20 feet from the home and elevated off the ground — wood piles are prime mouse nesting sites
  • Cut back dense shrubs planted directly against the foundation — they conceal entry points and provide shelter for mice approaching the home
  • Keep grass trimmed short within 3 feet of the foundation — tall grass provides cover for mice moving toward the home
  • Remove yard debris, leaf piles, and abandoned equipment near the home — all provide outdoor nesting and harborage

#5 When Prevention Isn't Enough — Call Hi-Tech

Prevention steps work best before mice are already inside. If you complete these steps in September — before Michigan temperatures drop — you dramatically reduce the chance of mice entering this fall.

But if mice are already inside your Farmington Hills home, prevention steps alone will not solve the problem. You must eliminate the existing population first — then seal. Sealing entry points while mice are already inside traps them — and trapped mice chew new holes through drywall, insulation, and wiring to escape.

⚠️ The most important rule: Eliminate first. Seal second. Never the other way around. Hi-Tech Pest Control eliminates the entire mouse population, then inspects and seals every entry point — in the correct order, every time.
