Entrance Disinfection Mats are designed to be placed at the entrance to dairy barns, hog enclosures, poultry houses and vegetable, fruit and grain storage facilities, to disinfect the boots and shoes of  workers as they enter. Mats are made with tough poly mesh over a foam core with non-permeable bottom and sides to contain the disinfectant solution.When filled, the Mats repel dirt and stay effective for approximately one week when they should be lifted, rinsed and left to hang-dry overnight. Mat must be used on level surface.
