Bed Bug traps and detectors are a monitoring tool. They will monitor and trap bed bugs before they climb up your furniture legs or when they leave the host furniture. Install these under every bed leg. The bed legs should rest in the centre of the detector, creating a bed bug barrier. Not only will these allow you to know when you have any bed bug activity by catching them in the perimeter of the trap, but these traps are also the best defence from preventing bed bugs from accessing your bed or furniture once you have encased your mattress and heat-treated your linen. You can "Get Back To Dreaming" knowing these are in place.
