Mice Indoors

  • I live on one acre in the country and am having big problems with field mice. I have trapped 20 in the last three weeks and they are driving me crazy. Any suggestions on how to get rid of the critters? What about poisons?

    It’s that time of year when rodents are seeking warm places with food to spend the winter. The first thing you should do is eliminate the food supply. Start in the garage. Keep dog food, bird seed, grass and garden seeds, in covered containers. Inside, all food in the kitchen must be kept in containers. Your next step should be plugging all the obvious holes. Use fine steel wool to stuff around pipes and drainage holes. Mice can not chew through it. You can also try covering up the holes with duct tape. Walk around the house foundation and fix any obvious entry ways. Remember that mice can fit through tiny spaces much smaller than their bodies! I would advise against using poisons. Poisons are harmful to children and pets. Animals like hawks, owls, and snakes could feed on a poisoned mouse and then become poisoned themselves. I would also invest in mousetraps that can be used over and over again. The last thing to consider is getting a cat. Cats are natural predators and can be very effective at getting rid of mice in and around your house.
