Pest and Wildlife Problems in a House
Pests follow food, water and entry points. Sustained indoor insect activity almost always signals a moisture source or an unsealed penetration, so treatment without correcting the conditions produces repeat infestations. Integrated pest management — exclusion first, targeted baiting second, broadcast spraying last — is the EPA-recommended sequence.
Insect infestation diagnostics
Insects indoors are a symptom of food access, moisture or an open entry line. These two guides walk through trail mapping, breeding-site tests and exclusion:
- why is my house infested with ants — Foraging trails, hidden framing leaks and colonies nesting inside wall voids.
- Why Is My House Infested with Ants? — Colony identification, bait choice and why spraying trails makes ant problems worse.
- Why Is My House Infested With Flies? — Drain tape tests, decaying matter in walls, cluster-fly gaps and dry p-traps.

Pests & Wildlife questions homeowners ask
Do I need a pro or can I bait myself?
Ants, drain flies and occasional spiders respond well to homeowner baiting and sanitation. Termites, rodents in wall cavities, and wildlife in attics require professional exclusion and, for termites, licensed application.
Why do the bugs come back after spraying?
Perimeter sprays kill what is present but do not remove the moisture, food or entry gap that attracted them. Exclusion and moisture correction are what make treatment stick.
