DIY vs. Call a Pro
Minor pest issues like occasional ants or spiders can be managed with store-bought baits, traps, and perimeter sprays. Seal entry points with steel wool and caulk. Keep food in sealed containers and eliminate standing water. Diatomaceous earth is effective for many crawling insects.
Call a professional when:
Hire a licensed pest control company for termite infestations, rodent problems, bed bugs, wasp nest removal, wildlife removal, or any persistent infestation that DIY methods haven't resolved. Professionals have access to regulated products and can identify the species for targeted treatment.
