A system for controlling pests such as bed bugs includes a channel configured to substantially surround a protected area. The channel includes an interior surface and an exterior surface. Powder is disposed on the interior surface, and a seal is disposed on the exterior surface. Seal 20 is configured to prevent bed bugs from traveling between the exterior surface and a third surface on which the system is to be installed, such as a floor. Bed bugs can not pass through the channel, since bed bugs would have to crawl up the exterior surface and into the interior surface, becoming stuck in the powder.
