TL;DR
Crack-and-crevice treatment is the targeted application of insecticide, dust, gel, or fine spray from a crack tip, directly into the gaps, voids, and expansion joints where cockroaches, ants, and silverfish actually live and travel. It contrasts with old-style baseboard spraying by putting material where pests harbor instead of on open surfaces people and pets touch, using less product to better effect.

Modern integrated pest management service reports list the treated harborage points rather than rooms broadly sprayed.
