Replaceable Glue Cartridges for BEAP Co’s Bed Bug Detection Trap. Bed bugs are attracted to porous materials with many crevices where they can hide. The textured base of the Detection Trap allows bed bugs to easily climb up into the trap, attempting to find a hiding spot, where they become trapped in the replaceable glue cartridge. Place between your box spring and mattress, seat cushions or on the ground near your bed for effective bed bug monitoring and trapping. The BEAP Co Detection Trap can also be converted into a Quick-Response Bed Bug Trap by utilizing our patented heat and C02 generating process (sold separately).
