Exterior prevention checklist
- Repair screens, weatherstripping, door sweeps, utility penetrations, and pest-sized gaps using materials appropriate for the opening.
- Keep vegetation, firewood, stored materials, and dense mulch away from the structure where practical.
- Correct standing water, leaking spigots, clogged drainage, and persistent moisture near the foundation.
- Use covered trash and compost containers and clean spills around outdoor eating or pet areas.
Interior prevention checklist
- Store pantry and pet food in durable closed containers and clean crumbs and grease promptly.
- Repair plumbing leaks and reduce condensation under sinks, around appliances, and in utility spaces.
- Reduce cardboard and clutter where pests can hide, especially in garages, basements, attics, and storage rooms.
- Inspect packages, used furniture, luggage, plants, and stored items before bringing them inside.
Exclusion needs inspection
Find active routes first
Sealing the wrong opening can leave the pest inside, redirect activity, or separate dependent young from wildlife. Identify current use before closing access.
Match material to pest and opening
Foam alone may not resist chewing. Vents, rooflines, masonry gaps, drains, and moving joints need compatible methods that preserve drainage and airflow.
Coordinate treatment and repairs
Some infestations require population control, sanitation, or monitoring before final exclusion and cleanup.
Verify after completion
Monitor for new droppings, sounds, damaged seals, or activity and document whether the repair actually changed the pattern.
