Having trouble assessing the infestation level? Inspection aerosols are useful tools to locate and flush out cockroaches from harborage areas that are not easily accessible. Think broadly, and do not restrict inspection to just well-known areas such as kitchens and bathrooms. Check all over. Are the cockroaches eating fish food near an aquarium in the living room?
Remember to think like a cockroach: Where can it find food, water, darkness and shelter — preferably all close together? Check all of those places.
