Demon WP is our most popular product for camel cricket control. It is a powder that you mix with water and apply using a 1 gallon hand pump sprayer. The powder is easy for the crickets to pick up on their bodies. You would spray the outside foundation around the home 2 to 3 feet up onto the foundation, and 2 to 3 feet out onto the ground. If you have access to the crawl space under the home, you should spray under there as well and if you have a basement you should spray the inside perimeter. You may need to apply once every 30 days until the problem is under control.
