Entry point sealing (exterior)
1. Seal gaps around pipes, conduits, and cables where they enter walls — use caulk or steel wool backed by foam. 2. Install door sweeps on exterior doors. 3. Repair or replace damaged window and door screens. 4. Check roof soffits and vents for openings. 5. Seal gaps around the foundation and where siding meets the foundation. 6. Cap or screen chimney flues. 7. Inspect and seal gaps around garage doors.
Moisture control
8. Fix leaking pipes and dripping faucets promptly. 9. Ensure gutters drain away from the foundation. 10. Address pooling water in the yard. 11. Ventilate crawl spaces and basements. 12. Use a dehumidifier in persistently damp spaces. 13. Check for condensation on pipes and address insulation where needed.
Food and waste management
14. Store dry pantry goods in sealed airtight containers. 15. Keep pet food in sealed containers and do not leave food out overnight. 16. Empty kitchen trash daily or keep it in a sealed bin. 17. Clean up food spills and crumbs promptly. 18. Rinse recyclables before placing in bins. 19. Keep compost bins away from the house with tight-fitting lids.
Landscaping and exterior
20. Keep firewood stored at least 20 feet from the house and off the ground. 21. Trim branches and shrubs that touch or overhang the roof and siding. 22. Clear leaf litter and mulch from the foundation perimeter. 23. Eliminate standing water in planters, bird baths, and gutters weekly.
Interior monitoring
24. Inspect pantry goods when purchased and periodically for signs of pantry pests. 25. Check under sinks and behind appliances quarterly for moisture, droppings, or activity.
When prevention is not enough
Prevention reduces risk — it does not eliminate it. If you identify an active infestation, structural pest activity (termites, carpenter ants), a recurring problem, or a health or safety risk, contact a licensed professional for an inspection. Correct identification before treatment is essential.
Frequently Asked Questions
Can I do pest prevention myself without chemicals?
Yes. Most prevention steps are non-chemical: sealing entry points, managing moisture, and eliminating food sources. These are the foundation of integrated pest management (IPM).
How often should I do a prevention check?
A seasonal walkthrough (4 times per year) is a practical frequency for most homes. Check exterior entry points and drainage in spring and fall, and pantry and interior moisture sources quarterly.
