This is made of garlic oil, white pepper, mineral oil and silica. Effective against multiple species, will not melt, evaporate or freeze. Also, this cleans up easily with soap and water. For safe application, don't forget to wear gloves and eye protection first. After that, employ the gel to prevent rodent entry or transit along any route. This is ideal for homes, schools, offices, warehouses and others. Apply rat-out gel to surfaces where rodents travel, such as beams, ceiling tiles, ledges, cornices, cracks, gutters, holes, HVAC, roofs and trees. This special formula also prevents rodents from eating wires, cables, and conduit. No sealing, pretreatment, or taping is required. The gel can be applied directly into gopher holes (back and front).
