How Do Rodents Get in Walls?

Rodents largely rely on humans for food, water, and shelter. This is why they go to extreme lengths to enter homes, squeezing through cracks as small as a quarter of an inch.

They tear insulation and build nests while bringing ticks, fleas, and mites with them. Rodents in walls are very annoying for many homeowners.

Problems with Rodents in Walls


Unsanitary conditions develop soon after rodents move into the walls. The pests' droppings pile up quickly, creating a musty smell that can linger for weeks.

Homeowners who try to clean up rodent waste should take extreme caution, as contact can lead to Hantavirus, leptospirosis, and other illnesses.


During the night, rodents in wall voids annoy residents with the rubbing and scratching sounds they make while moving around.

They also create loud noises while gnawing wood and drywall, causing unease and possible structural damage. Residents may hear squeaking as well when rodents in the walls communicate with each other.


Rodents in the walls often uses structural voids to move from attics or basements into other areas like kitchens and bedrooms. This is when residents are at the greatest risk from the pests' waste and parasites.

Common rodent diseases include rat-bite fever, salmonellosis, and bubonic plague.

Ridding the Home of Rodents

Because many structural gaps are hard to access, it can be difficult to locate and remove rodents in the walls. It is even worse when the pests die in these areas, as issues may arise with odors and pest insects.

Call Critter Control at the first signs of rodent infestation to prevent further damage.

BAT POOP CLEAN-UP AND PREVENTION! Bat guano removed from gables. No bats found in attic, so put new screens on all gable vents, as one screen was close to breaking and then bats may have gotten in! Great work in Tulsa!

Squirrels and chipmunks were in our attic. So we called Critter Control to do an inspection. Their representative climbed all over our very steep roof and found several places where squirrels had entered our attic.

Upon inspection of the attic, evidence of bats was also found. The Critter Control team came on time to completely caulk the entire perimeter of the house and create an exit strategy for the squirrels and bats.

Because bat droppings can cause histoplasmosis, this also required total removal and replacement of our attic insulation and sanitizing the space. Not a small job in a 1,300 sq. ft. attic! While Critter Control’s cost was high, our homeowners insurance covered most of it. Everyone representing Critter Control was professional, courteous and timely. I would highly recommend them to anyone who thinks they might have unwelcome guests living in their attic

On recommendations from a nearby pest control company, I called Critter Control for suspicious bat droppings.

Madison came out the same day to do an inspection. She was knowledgeable, thorough, and highly professional. She examined the ‘matter’ that had been scattered on my threshold and thought it was foliage. But she then asked to go up to my attic space where the bats could be roosting. She had to walk up 3 flights of stairs with a heavy ladder. She again spent some time searching all the nooks and crannies and found nothing.

She seemed so interested in her craft, it was truly inspiring to see! She reassured me and is writing up a prevention strategy for my appraisal. She charged me NOTHING!! I am so impressed. We need more Madisons in this world!

We noticed droppings on our brand new deck - we were given their number from our contractor. They came the next day. Brian looked at it and said - yeah, bats!! He then checked every area in our attic and he explained exactly what needed to be done.

He found evidence of a mice infestation, provided a referral and they are helping us as well. Great service, very informative, very professional! We are very satisfied and would recommend them to anyone who has any issues with any critters!
