New and improved thicker polypro design to resist cracking.’ Climbup Insect Interceptors are a unique and easy-to-use monitoring system to aid in the early detection of bed bug infestations. These specially designed plastic cups are pesticide-free and are too slick for the bugs to crawl out. Talc powder is optional for best results, but is not required and not included. Bugs approaching the bed (or other furniture) from the floor will fall into the outer well while bed bugs leaving the bed will get stuck in the center well. Allows early detection for bed bugs and also aids in protecting furniture from reinfestation.
