TL;DR
Pest exclusion is the structural side of pest control: sealing the openings animals and insects use to enter a building with materials they cannot defeat — hardware cloth on vents, copper mesh and sealant in gaps, door sweeps, and chimney caps. Mice pass through holes the width of a dime, so the inspection maps every penetration before sealing begins.
What it means
Pest exclusion is the structural side of pest control: sealing the openings animals and insects use to enter a building with materials they cannot defeat — hardware cloth on vents, copper mesh and sealant in gaps, door sweeps, and chimney caps. Mice pass through holes the width of a dime, so the inspection maps every penetration before sealing begins. Done thoroughly, it is the lasting fix that trapping and spraying alone never provide, and companies typically warranty the sealed points.
