Call a pro 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.
