Squirrels are a familiar sight in Sacramento, scurrying across tree branches, darting along fences, or raiding bird feeders. At first glance, they seem harmless, even entertaining. But when squirrels move from your yard into your attic or crawlspace, they can cause significant headaches for homeowners.
At Pest Pros Pest Solutions, we frequently receive calls from residents of Sacramento and surrounding areas who are surprised by just how destructive squirrels can be indoors. Understanding why squirrels cause problems, the signs of their activity, and how to prevent infestations can help protect your home from costly damage.
Why Do Squirrels Enter Homes?
Squirrels are naturally curious and resourceful. In the wild, they build nests in tree cavities or leafy branches. In Sacramento neighborhoods, attics, chimneys, and sheds provide even better shelter: warm, dry, and close to food sources.
They often enter homes by:
Chewing through vents or soffits
Squeezing through small gaps in roofing
Using overhanging tree branches to access the roof
Once inside, squirrels quickly establish nests and may return year after year if the entry point isn’t sealed.
What Kind of Damage Can Squirrels Cause?
Squirrels may look small, but their presence indoors can lead to big problems. Their teeth never stop growing, so they gnaw constantly to keep them trimmed down. Unfortunately, this means your home becomes their chew toy.
Some of the most common issues include:
Chewed Wires – Creating fire hazards and costly electrical repairs
Damaged Insulation – Shredded for nesting material, reducing energy efficiency
Structural Damage – Gnawed wood beams, fascia boards, or siding
Noise Disturbances – Scratching, scampering, and squeaking, especially in the early morning
In addition to damage, squirrels leave behind droppings and urine, which create odors and attract other pests.
Are Squirrels Dangerous?
Squirrels are not typically aggressive, but they can pose health and safety risks. Their droppings may harbor bacteria and parasites, and they can introduce fleas and ticks into your home. If trapped or cornered, a squirrel may bite or scratch in self-defense.
This is why professional handling is always recommended. Attempting to remove squirrels on your own can be risky and rarely solves the problem long-term.
How Do You Know If You Have a Squirrel Problem?
Because squirrels are active during the day, homeowners sometimes spot them coming and going from rooflines or vents.
Other common signs include:
Persistent scratching or running noises in the attic
Gnaw marks on wood, wires, or siding
Shredded insulation or nesting materials
Foul odors from droppings or urine
If you notice these signs in your Sacramento home, chances are squirrels have moved in.
Preventing Squirrel Infestations
Keeping squirrels out of your home is easier than dealing with an infestation after it starts.
Preventive steps include:
Trim trees and branches at least six feet away from the roofline
Seal entry points around soffits, vents, and rooflines with durable materials
Use squirrel-proof bird feeders and avoid leaving food sources outdoors
Schedule regular inspections to catch problems early
What to Do If Squirrels Are Already Inside
Once squirrels are established in your attic or crawlspace, they won’t leave on their own. In fact, they may return season after season to raise young. DIY trapping or relocation often leads to incomplete removal, and sealing entry points without addressing active squirrels can trap them inside, creating even bigger problems.
That’s why Sacramento homeowners often turn to Pest Pros Pest Solutions. Our team understands squirrel behavior and uses proven, humane methods to remove them, seal entry points, and help prevent future invasions.
