How Do You Keep Pests Out of Your Ajax Home This Winter?

A fall and winter checklist for homes in south Ajax by the lake, Ajax’s historic downtown, and the newer subdivisions in north Ajax.

Quick Answer

To keep pests out of your Ajax home this winter, seal small gaps around pipes, vents and garage doors before November, cap your chimney, trim branches back from the roof, and store food and birdseed in sealed containers. Mice, squirrels and raccoons look for warm shelter as the weather turns, and boxelder bugs and ladybugs slip in through window and siding gaps. Sealing entry points in fall is far easier than removing pests in January.

Which Pests Try to Get Into Ajax Homes in Winter?

• Mice: the most common winter pest. They move in from September to November.
• Squirrels: chew into soffits and roof vents to nest in warm attics.
• Raccoons: look for denning spots in attics, chimneys and under decks.
• Boxelder bugs and ladybugs: gather on sunny walls in fall and squeeze inside to overwinter.
• Rats: less common, but they shelter in garages and sheds near creeks. Read how to keep rats out of your garage.

Why Ajax Homes Are Prone to Winter Pests

Ajax has a long Lake Ontario waterfront, with Rotary Park and the waterfront trail close to many south Ajax homes. Carruthers Creek runs through town, and green corridors follow it north. Wildlife and rodents use these areas and move into nearby backyards when it gets cold.

Older homes in Ajax’s historic downtown often have aging foundations and soffits. Newer homes in north and northeast Ajax can have unsealed gaps around utility lines, siding and garage doors from construction.

Your Fall Pest-Proofing Checklist

1. Seal gaps: check where pipes, gas and cable lines enter the house and seal any gaps. A mouse fits through a gap the size of a dime.
2. Garage doors: replace worn bottom seals so there’s no gap when closed.
3. Vents: make sure dryer, bathroom and roof vents have covers.
4. Chimney: install a chimney cap to keep raccoons and birds out.
5. Trees: trim branches back from the roof so squirrels can’t jump on.
6. Soffits: look up for loose or chewed soffit panels and fix them.
7. Windows and siding: caulk gaps where bugs can crawl in.
8. Food: store pet food and birdseed in sealed hard containers.
9. Firewood: keep it off the ground and away from the house.

What If Pests Are Already Inside?

If you hear scratching in the walls or attic, see droppings, or find bugs clustering on window sills, sealing alone isn’t enough. Animals or rodents need to be removed first, and in an attic the entry point should only be sealed once everything is out.

Frequently Asked Questions

When should I pest-proof my home in Ajax?

Ideally in September or October, before nights get cold. That’s when mice and squirrels start looking for winter shelter.

Do mice come back every winter?

They will if the entry points stay open. Sealing gaps is what stops them from returning each year.

Are boxelder bugs and ladybugs harmful?

They don’t bite or damage the house, but they can gather indoors in large numbers. Sealing gaps around windows and siding keeps most of them out.

Is it safe to block a hole if an animal might be inside?

No. Sealing an entry point while an animal or its young are inside can trap them. Humane one-way exclusion lets them leave first.
