Cracks and Gaps in Windows and Doors

Doors and windows are prime entry points for pests, particularly where there are gaps or cracks. Even small openings around windows or under doors can let in ants, spiders, and even rodents. Caulk any gaps around the window frames and consider adding weatherstripping around doors to ensure a tighter seal. Recheck these areas at the start of each season, as seals can wear down over time.

Foundation Cracks

Homes naturally settle, which can lead to cracks in the foundation or walls. These cracks, though sometimes small, are like open doors for pests like ants and termites. For smaller cracks, a silicone-based caulk works well, while expanding foam is ideal for larger gaps. For significant structural cracks, it’s wise to consult a professional.

Vents and Utility Openings

Vents and utility lines entering your home through the walls can also provide entry points for pests. Use mesh screens to cover vent openings and apply weatherproof sealant around pipes and cables. This is especially important for dryer vents, kitchen exhausts, and other access points where pests like rodents and insects may enter.

Attic Openings and Chimneys

Rodents and larger pests are known to seek shelter in attics and chimneys. Cover attic vents with vent covers and cap chimneys to keep animals out while still allowing for ventilation. Inspect these areas regularly, especially if you hear scratching or rustling sounds, which could indicate that pests have already gained entry.

Garage and Basement Doors

Garages and basements often go overlooked, but they can be easy targets for pests. Install door sweeps on garage doors to block entry and make sure that basement windows are properly sealed. Consider adding screens to basement windows or vents as an added layer of protection.
