Rodent Frequently Asked Questions
Here are answers to some common questions about mice and rats.
-
Why do I have mice or rats in my home?
Mice and rats often enter homes seeking food, water, and shelter. Even the smallest openings—about the size of a dime for mice and a quarter for rats—can be entry points. They’re especially drawn to areas with accessible food sources like pet food, crumbs, or open garbage.
-
What are the signs of a rodent infestation?
Common signs include droppings, gnaw marks on food packaging or furniture, nests made of shredded material, scratching noises (especially at night), and a musty odor. Grease marks along walls or baseboards are also a strong indicator of frequent rodent travel paths.
-
How quickly can a mouse or rat infestation grow?
Mice reproduce extremely fast—a single pair can produce up to 60 offspring in a year. Rats are slightly slower but still rapid breeders. This means a small problem can escalate into a major infestation in just a few months if not addressed promptly.
-
Are mice and rats dangerous to humans?
Yes. They can carry and spread diseases like salmonella, hantavirus, and leptospirosis through their droppings, urine, and saliva. Their constant gnawing can also damage wiring, insulation, and structures, increasing fire risks and costly repairs.
-
What can I do to prevent mice and rats from coming back?
Seal all cracks and openings around your home, store food in airtight containers, keep garbage tightly closed, and maintain clean, clutter-free spaces. Regularly inspect attics, basements, and crawl spaces for signs of activity. If infestations persist, professional pest control is recommended for long-term prevention.
