Which type of pesticide application would you use to control cockroaches inside buildings?

• A. Basal.
• B. Band.
• C. Crack & Crevice.
• D. Directed spray.

Answer: (C)

Getting cockroaches that live inside buildings requires treating the places they hide rather than spraying open surfaces. Cockroaches spend most of their time in cracks, seams, voids behind baseboards, in wall voids, and under appliances. A crack-and-crevice application targets those exact harborage sites by applying pesticide into the crevices where roaches travel and hide, delivering effective contact and residual control while minimizing occupants’ exposure and reducing the amount of product used. Other methods like spraying along baseboards, treating open surfaces, or applying a band around the structure miss hidden roaches or create unnecessary exposure indoors. So, crack-and-crevice is the best fit for interior cockroach control.
