Mice inside home

Asked January 22, 2018, 9:20 AM EST

What is best trap to use inside? What are most likely openings outside? What do we seal them with? Can we use indoor traps outside near an entry point such as sliding Door? We have had 5 mice in 1 week. Need help. Thank you

The best recommendation is to prevent them from coming indoors by using a 3 part approach - sealing up, cleaning up, and trapping. Seal cracks and openings under doors (including garage doors), in building foundations and any openings for water pipes, electric wires, sewer pipes, drain spouts, and vents. Seal up holes, cracks or crevices larger than ¼”. Plug holes around the foundation or other areas with hardware cloth, sheet metal, or steel wool.

Mice tend to enter homes in the fall when colder weather drives them indoors and then they can become a real problem. Mice readily adapt to a variety of habitats, feed on most human and pet food and reproduce at a remarkable rate. Conventional snap-type mousetraps are the most effective means of control. There are also jaw type that require no bait. If you trap outdoors, use a bait station. See what works best for you.

Store any potential food source in metal or other rodent proof containers. Look for and clean up any possible nesting sites and nesting material such as paper or fabrics. Place the traps in the areas where you notice the most mice activity. Bait them with peanut butter and oats or a cotton ball tied to the trigger (female mice like to use these for nesting). The trap should be placed against the wall so it forms a ‘T’ with the trigger facing the wall. Wear disposable gloves when handling used traps. After several weeks of trapping, and habitat modification, you should be able to eliminate the problem of mice. http://extension.umd.edu/hgic/mice
