ActiveGuard Mattress Liners ('ActiveGuard') are a revolutionary mattress and box spring product that kills bed bugs and dust mites. This EPA-registered ‘active mattress liner’ has no use or precautionary word restrictions and is the only pro-active preventative approach for stopping bed bug infestations before they establish…once installed, the liner continuously works for two years and is maintenance-free. ActiveGuard does not trap or encase bed bugs but rather kills them protecting not only the mattress but the person sleeping on it! Supported by years of published scientific lab and field studies as part of comprehensive bed bug control strategies or as a preventative, these liners will continue to kill bed bugs (and dust mites) well after all other chemical residual approaches have been exhausted. Soft and comfortable, ActiveGuard is impervious to ripping and tearing; there is no need for replacement if it does rip…it continues to work! Installation is as simple and quick as when changing your bed linens. There's no need for 20+ SKUs; only four sizes (Single/Twin, Double/Full, Queen and King) fit almost every available mattress or box spring, and accommodate up to XL in length and 17" in depth.
