How to do a CRACK & CREVICE Treatment

Definition of Crack and Crevice Treatment:

The application of small amounts of insecticide into cracks and crevices in which insects hide or through which they may enter the building.

  • Such openings commonly occur at expansion joints, between different elements of construction and between equipment and floors.
  • These openings may lead to voids such as hollow walls, equipment legs and bases, conduits, motor housing, junction or switch boxes.

Concept of Crack and Crevice Treatment

  • The goal of Crack & Crevice treatment is to deliver the insecticide to a specific location where it is likely to impact the pest with little or no impact on the area surrounding the treatment site.
  • The effect may be repellency (exclusion from the site) or may be used during inspection to flush insects (identifying infested areas).
  • It may be used in sensitive areas where limiting pesticide exposure is an important consideration.


Gaps between structural members, behind moldings, between pieces of equipment, etc.
