Tips & Warnings
In its own environment mice have a foraging range of only 10 feet from their nest. Rats have a much larger foraging range. To prevent future problems repair any entrances 3/8 inch or larger. Stuff fine steel wool up the corners of the structure. You will start to get results in 4 to 5 days but allow 30 days for the problem to clear up. Rebait as necessary. For foul odor, find and remove any bodies and use a masking agent, i.e. moth balls until odor subsides. It is better to have a little foul odor than to have live mice or rats. They gnaw on everything, including electrical wiring. Their teeth continuously grow, so they have to gnaw to keep their teeth a certain length so they can feed.
When moving insulation wear a dust mask to prevent breathing in of dust and fibers. Washs hand before preparing food or eating.
