The Mouse Glue Boards (MODEL - TM2815) have proven their ability to catch mice under the toughest conditions possible-their own natural environment. So when we say they work we're not basing our findings on lab tests. Rather real live tests. The secret is simple, the use of long lasting, atmosphere-enduring, and instant catch-on-contact glues. TRAPPER Glue Boards capture rats and mice without poison. The glue boards are ideal to use in food plants, kitchens, restaurants, food processing plants, hospitals, residences, zoos and other sensitive areas where the use of poison is prohibited or discouraged. TRAPPER's sturdy, low-profile plastic tray reduces the chance of rodents stopping at the edge of the tray. Once rodents step onto the glue board, TRAPPER's tenacious glue holds a rat securely, while just the slightest contact with the glue will hold a mouse. TRAPPER Glue Boards come in rat and mouse sizes. For best results, place TRAPPER Glue Boards directly in the rodent's runway between its nest and food supply -- every 8 to 12 feet for mice and 15 to 30 feet for rats.
