Crack and Crevice Treatment
Pesticide application method that places insecticides directly into cracks, crevices, and voids where pests hide, minimizing exposure to people and pets.
Detailed Overview
Crack and crevice treatments target pesticides precisely where pests live and breed, rather than applying broadly to exposed surfaces. Formulated insecticide is applied with a tip or injector into narrow openings, gaps around pipes, wall voids, and other protected harborages. The application is so precise that the pesticide should not be visible to a bystander during or after application. This method maximizes pest exposure while minimizing human and pet contact with pesticides. Crack and crevice is the only acceptable spray application method in IPM programs.
When to Use
Use for cockroaches, ants, and other insects that hide in structural voids and crevices. Apply only where monitoring indicates pest presence. Never use broad surface sprays or foggers.
