There’s a mouse on my house! A tiny, grey furred mouse (probably Mus Musculus) was actually climbing a brick wall near a bathroom window almost 5 feet from the ground! This is definitely a good reason to keep window screens in good repair and unscreened windows closed. A review of seals around the garage and other doors door is next. According to Des Plaines Public Works, a mouse can squeeze into an opening the size of a dime.
They are omnivorous but prefer seeds, grains and nuts. Check the area under bird feeders and use squirrel guards to also keep mice out. Keep garbage in closed containers and clean up pet food promptly. This will also help keeps skunks and opossums, a bigger problem, elsewhere. Most mice have a 1 year life span, but can start breeding as soon as 1.5 or 2 months producing 8 to 10 litters with 3 to 16 young. One female mouse can produce as many as 160 more!
A neighbor suggested a trap baited with peanut butter or bacon. He claimed that one sighting was a sign of many more. Because their teeth continue growing throughout their lives, rodents gnaw on plastic, cinder blocks, soft metal such as lead and aluminum or electrical and cable wires. Animalwardens.co/uk warns that rodents are incontinent and leave a trail wherever they go.
Mice are usually active at night, but the young without established territories feed when dominant males are away. As long as this one, and family, stay outside with the stray cats, hawks and other creatures I promise to take preventive measures only. Come indoors; the traps will be set. See windycitywildlife.com.
