Instead, they inhabit wildlands or croplands adjacent to buildings or gardens and landscaped sites with protective ground cover. Their ears are furred and project slightly above the fur on the head. If feasible, weed-free strips can serve as buffers around areas requiring protection. Studies of food supplementation in small mammals often result in significant increases in population density. Did You Know? Nests They probably are the safest type of rodent bait for use around homes and gardens, because they are slow acting, must be consumed during a period of 5 or more days to be effective, and have an effective antidote, vitamin K1, making it safer to use around children and pets.
