What is mouse habitat?
Almost any place overgrown enough for mice to hide in – woodpiles, stone walls, foundations, woodlots, etc. Some are less obvious and depend on the characteristics of your yard. Flower beds and perennial beds, if they are dense, are good candidates – and so is high grass. Plantings alongside your house foundation or porch are also worth treating. Mown lawns and driveways are not mouse habitat. You can also test various locations. That is, you can put out tubes and monitor them over a few weeks. If the cotton is undisturbed and the tube is full it means that there is no mouse living nearby. If that is so, move the tube to a likelier location. For the treated area, the maximum distance between the tubes should not exceed 10 yards in any direction.
