Keeping your animal enclosures or food storage facilities clean and safe has never been easier! Simply place this Disinfectant Mat at the entrance to hog pens, poultry houses, animal premises and fruit, vegetable or grain storage facilities. When saturated, the mat disinfects boots and shoes as workers or visitors enter. Use with Virkon Disinfectant Item #151210 (sold separately). NOTE: It's recommended to rinse, dry and refill disinfectant mats weekly. Not recommended for use with chlorine-based disinfectants.
