Rodent Proofing Your Home

If you’ve ever heard scratching in the walls at night or found tiny droppings along your baseboards, you already know the feeling. It’s unsettling. You start wondering, How did a mouse even get in here?
Here in San Bernardino, mouse problems are more common than most homeowners think—especially in the cooler months when rodents start looking for warmth, food, and shelter. And the truth is, mice don’t need much of an opening to get inside your house. A gap the size of a dime is enough.
That’s where mouse exclusion comes in.
If you’re searching for how to seal mouse entry points in San Bernardino or how to stop mice from getting inside walls, this is exactly what you need to know.
How Mice Are Getting Inside Homes in San Bernardino
Most people picture a big hole chewed through the wall. That happens sometimes—but more often, mice are slipping through openings that were already there.
Common entry points we see in North San Bernardino homes include:
Small gaps around plumbing pipes under kitchen and bathroom sinks
Openings around AC line sets
Gaps along garage door corners
Foundation cracks
Roofline and attic vent gaps
Weep holes along brick and stucco
Because our area has mild winters, mice stay active year-round. When temperatures dip at night, they look for insulated walls, attics, and garages to nest in.
Once inside, they don’t just visit. They settle in.
The Holes Mice Make Inside Your House
After they get in, mice start creating their own pathways. They chew through drywall, insulation, cardboard storage boxes, and even wiring.
If you’re noticing:
Small jagged holes in drywall
Gnaw marks along baseboards
Shredded insulation
Chewed food packaging in the pantry
Greasy rub marks along walls
…those are signs you’re dealing with an active mouse infestation in San Bernardino.
And here’s the part most people don’t realize: trapping mice without sealing entry points is like bailing water out of a boat without fixing the leak.
If the holes aren’t sealed, more will keep coming.
Why Mouse Exclusion Is So Important
A lot of pest control companies will set traps and call it a day. But true rodent control in San Bernardino requires more than that.
Exclusion is the process of finding and sealing all mouse entry points so they physically cannot get back inside.
Why does this matter?
Because mice reproduce quickly. One pair of mice can turn into dozens in just a few months. If even one female gets back inside, the problem starts all over again.
Sealing rodent entry holes protects your:
Walls and insulation
Electrical wiring
Food storage
Indoor air quality
Family’s health
Mice carry bacteria, contaminate surfaces, and trigger allergies. It’s not just a nuisance—it’s a health concern.
Why DIY Sealing Doesn’t Always Work
It’s common for homeowners to try stuffing steel wool into visible holes or spraying foam into cracks. That can help temporarily.
But mice are persistent. If materials aren’t installed properly—or if secondary entry points are missed—they’ll chew around the repair or find another way in.
Professional mouse exclusion services in North San Bernardino involve:
Full exterior inspection
Identifying primary and secondary entry points
Using rodent-proof materials
Proper sealing techniques that hold up long term
The key is understanding how mice behave and knowing where they’re most likely to travel.
Why North San Bernardino Homes Are Especially Vulnerable
Homes in the San Bernardino area often have:
Expansion gaps from shifting soil
Older vent screens
Stucco cracks
Garage-to-home access points
Landscaping that touches the structure
All of these create opportunities for mice to enter.
Add in nearby open land, washes, and foothill areas, and you’ve got the perfect environment for rodent activity.
If you’re hearing scratching at night or seeing droppings in the garage, it’s not random. It’s a sign there’s an access point that needs to be sealed.
The Right Way to Handle a Mouse Problem
Effective mouse control in San Bernardino involves two steps:
Remove the current mice.
Seal every possible entry point.
