This is important if you have a lot of reproduction going on in the walls. If you have a crawl space in addition to the basement, make sure to treat it as well. Sprinkle the Delta Dust throughout or apply it with the Dustin Mizer for those hard to access spaces. Such treatment is critical for long term success. In most cases, if these areas are treated right in the first place, the crickets never come back.
Most people believe ants or roaches are more likely to live in such dark and damp areas.
Although some may, most would much rather be in the living area of your home where it is warmer and better food is available. Camel Back Crickets are one insect that truly wants to be in the crawl space. Therefore, to solve the problem, you need to get them where they live. Crickets are a common problem around the home and yard. Camel back crickets will almost always infest crawl spaces or basements if left to do as they please.
