One package Contains 4 Traps 5′ wide by 22′ long. To protect your vehicle, aircraft, boat etc from the destruction of mice. Simply remove the paper covering from the sticky board and place around the wheel. Overlap boards for complete protection. Helpful tips: When placing boards down start with the inside part of the wheel first. Then the front and rear and finish with the outside. Be sure to overlap ends. For removal of wheel guards cover sticky surface with paper and cut with scissor to remove. For adhesive removal on hands use vegetable oil. If you would like to save the captured critter simply Pour a little vegetable oil over the mouse’s feet, coating it lightly, and the surrounding area of the trap. Use just enough oil, maybe a spoonful or two at most. Any sort of cooking oil works, but vegetable oil works best and tends to be the least expensive. NEVER USE ANY KIND OF PETROLEUM, SYNTHETIC OR LUBRICATING OIL IT WILL KILL THE MOUSE. Make sure that the mouse’s mouth and nose are not submerged in the oil. Again, it takes very little oil.
