Florida Pest Answers
"I keep hearing faint scratching and scurrying in my walls at night. What sounds do rodents make, and do I have an infestation?"
Different rodents make distinct sounds depending on their size and schedule. Nighttime scratching, scurrying, and gnawing typically point to mice or rats, while daytime activity usually means squirrels.
Nighttime Noises: Mice & Rats
Do mice make noise at night? Yes, but vocal squeaks are actually rare. If you are wondering what sound does a mouse make as it moves through walls, expect light scratching and rapid scurrying.
When nesting, mice create faint rustling and paper-crinkling sounds as they shred insulation and cardboard.
Rats are larger, so their movement in ceilings sounds louder, heavier, and more deliberate. Rats also create persistent gnawing sounds as they chew wood, plastic, or electrical wiring.
Daytime Noises: Squirrels
Mice and rats run the night shift, but squirrels are more likely to be the active intruder during daylight. Energetic scrambling, rolling, or scratching in an attic during morning or late afternoon hours indicates squirrels rather than mice or rats.
When Do Rodent Noises Signal an Infestation?
Hearing rodent noises alongside dark droppings, chewed packaging, or musty odors confirms an active infestation. Rodents contaminate surfaces and spread diseases like leptospirosis, salmonellosis, and hantavirus.
Pest technicians can locate entry points and recommend durable exclusion methods for both residential homes and commercial businesses to seal gaps and prevent pests from returning. Never ignore persistent scratching. Contact a qualified rodent exterminator for a free inspection and tailored control plan.
