Prevention tips for South Shore homes

The best intervention is the one you avoid. Here's a seasonal prevention program designed specifically for South Shore homes, based on the most common pests for each period.

In spring (March-May)

Inspect the foundation after thaw to detect cracks from thermal variation. Check soffits and vents for any trace of animals that overwintered in the attic. Cut branches touching the house before leaf-out. Place carpenter ant baits at first winged-ant sightings.

In summer (June-August)

Regularly inspect eaves, decks and shrubs for forming wasp nests — much easier to eliminate in June than August. Check compost bins: they must be airtight to not attract flies, raccoons and rats. Keep lawns mowed short near foundation to avoid rodent shelter.

In fall (September-November)

The critical season. Most winter infestations establish in fall. Meticulously inspect the exterior: foundation, vents, ducts, garage doors. Seal any opening over 6 mm. Check attic insulation — if compressed or holed, often the work of squirrels or mice. Consider preventive exterior treatment against boxelder bugs in September.

In winter (December-February)

Winter pests are mostly rodents and some diapausing insects (boxelder bugs, Asian beetles). Monitor sounds in walls and ceilings. Check fall-placed baits. Also a good time to plan renovations improving tightness (window replacement, insulation).

Year-round mistakes to avoid

Don't leave pet food outside at night. Don't stack firewood against the house. Don't ignore a single mouse or cockroach seen — what's visible always represents a fraction of the real population. And especially, don't wait until the problem is critical: costs triple when infestation is established.
