House Mouse (Mus musculus) in Polk County, FL

The house mouse (Mus musculus) is the dominant small rodent in Polk County, occurring in both residential and commercial settings across all submarkets. House mice are 3–4″ body + 3–4″ tail, gray to brown, with large ears and small dark eyes. They breed continuously in Polk County's year-round warm climate — a single pair can produce 35–60 offspring per year.

Quick answer. House mouse: 3–4″ body, gray, large ears. Enters through gaps as small as 1/4″ (dime-sized). Treatment: structural exclusion (seal all dime-sized gaps) + interior snap trap-out + perimeter bait stations. Mice die in inaccessible spaces — trapping is preferred over interior bait for residential.

House mouse vs. juvenile rat

Common confusion: young rats look like adult mice. Differences: head size — adult mice have proportionally larger heads relative to body; juvenile rats have smaller heads with chunkier bodies. Feet — juvenile rats have proportionally larger hind feet (preview of adult size). Droppings — mouse droppings 1/8–1/4″ with pointed ends, rat droppings 1/2–3/4″ with blunt ends.
