House Mice
The House Mouse is one of the most common indoor pests found in South Florida homes, condos, and businesses.
Small, fast, and adaptable, these rodents can squeeze through openings as tiny as ¼ inch, nesting in walls, attics, and storage areas.
Once inside, they breed quickly and contaminate food, surfaces, and air with droppings and dander. A single pair of mice can produce dozens of offspring in just a few months – making early detection and professional control critical.
What House Mice Look Like
House mice are small, grayish-brown rodents with large ears and a pointed nose. They’re smaller and lighter than rats, but just as destructive in confined spaces.
Key identifying features include:
- Size: 2½ to 4 inches long (plus 3–4 inch tail)
- Color: gray to light brown with a lighter underside
- Small, slender body and large ears
- Droppings about ⅛ inch long, pointed at both ends
- Often seen darting along walls or behind appliances
Behavior and Nesting Habits
House mice are nocturnal and thrive in warm, cluttered indoor spaces where food and shelter are nearby.
They’re highly curious and can climb, jump, and squeeze through small cracks — making nearly any structure vulnerable.
Common nesting sites include:
- Wall voids and insulation
- Under appliances and cabinets
- Garages, pantries, and storage closets
- Attics and crawl spaces
- Inside boxes, furniture, and cluttered basements
Mice use shredded paper, insulation, and fabric to build nests and will often gnaw through packaging to access food.
Signs of a House Mouse Infestation
- Tiny droppings around food storage or baseboards
- Scratching noises in walls or ceilings at night
- Gnaw marks on wires, cardboard, or food containers
- Grease trails along walls or behind furniture
- Strong, musty odor in enclosed spaces
- Pets behaving unusually or pawing at walls
⚠️ If you see even one mouse, there are likely more hiding nearby — infestations grow quickly.
House Mouse FAQs
How can I tell if I have mice or rats?
Mice are smaller, with thin tails and fine droppings. Rats are larger with thicker tails and droppings the size of rice grains.
Are house mice dangerous?
Yes. They can spread diseases like salmonella, contaminate food, and trigger allergies and asthma.
Do mice bite?
It’s rare, but they can bite if cornered. The greater danger comes from contamination, not aggression.
Can I get rid of mice myself?
Traps may catch a few, but mice breed quickly and nest in inaccessible areas – professional treatment ensures full removal.
Do mice come back after treatment?
Without proper exclusion (sealing entry points), reinfestation is likely. Our programs include both removal and prevention.
