ActiveGuard Mattress Liners, used as part of a bed bug treatment and control strategy, kill bed bugs dead within 72 hours and provide peace of mind as a revolutionary alternative to encasements. Developed as a natural extension of the globally used mosquito nets, ActiveGuard kills bed bugs in mattresses and box springs. Superior to any other bedding cover, the breathable, thin ActiveGuard Mattress Liners can be installed onto a mattress or box spring by one person in less than a minute, and the liners are comfortable and provide security that no other mattress covering or product can deliver. ActiveGuard Mattress Liners require no airborne sprays or powders, and are not subject to the ripping and tearing frequently experienced by encasements often rendering them useless. ActiveGuard Mattress Liners also have been lab and field tested on a variety of bed bug strains by research entomologists. It is one of the few bed bug products with both published lab and field data.
