How to take care of nuisance wildlife, rodent and pest problems? This is Edward, Critter Control here at Tampa Bay. There's a number of things that will help to repel mice. But first of all remember the biology of this animal. A tremendous sense of nose, their all factory senses are fantastic. So anything that smells a little off, there's going to probably repel them. You could even start with bleach. Cleaning, improving the sanitation; that's going to help to get rid of the mice. Naphthalene moth balls; that's a fume again, so be careful. There's a lot of people out there that are allergic to it; that are hyper-sensitive to naphthalene. You may have to take it all out of the attic if you throw it up there. I wouldn't use it to repel the mice. If you do, make sure you put it into a nylon sock, tie it off with a string and then put it where you want the odor. But you know what? The scents that repel mice are just going to move them. They're going to move them two feet or twenty feet. Mice don't truffle on off a long way, so you still have your problems. You still have to take care of the food, the water and the shelter which are the attractions for the mice in the first place. So if you're using a fume again like naphthalene; if you're using ammonia; if you're cleaning with bleach; boy, make sure you're not fooling yourself by just trying to use a scent to repel those mice. If you're having problems, call a professional. This is Ed with Critter Control in Tampa Bay.
