If you live in Naperville, Illinois, you already share the neighborhood with squirrels. Trouble starts when one finds a soft spot and moves indoors. This guide walks Naperville homeowners through signs, removal methods, and typical costs before choosing a provider. In most states, squirrels are classified as game animals with hunting seasons and wildlife regulations.

Squirrel removal is routed under “Rodents” in the provider network’s categories. Change it only if your issue is something else.
Squirrel removal in Naperville typically takes one to two weeks from inspection to final seal. Book the inspection early so nesting season does not delay removal in Naperville.
This page is for Naperville property managers, hotel operators, and anyone in the Naperville area dealing with a squirrel problem or wanting to prevent one.
a squirrel's teeth grow constantly, so the animal must gnaw to wear them down, and Naperville attics offer plenty of material. In a Naperville attic, that gnawing lands on rafters, PVC pipes, and electrical cable. Damaged wire insulation is the single biggest reason Naperville providers push for fast removal. squirrels are more likely to move indoors during stretches of cold, wet weather and during nesting seasons.
Most Naperville attics have one main entry and several test holes. A good inspector finds all of them, notes fresh rub marks and hair, and photographs each for the Naperville estimate.
Expect the provider to reinforce weak spots before they become holes. Softened fascia, roof-edge gaps, and construction gaps in Naperville homes are where the next hole will appear.
In Naperville, the exclusion door approach is generally the lowest-stress option for both homeowner and squirrels. It requires patience, because the animals leave on their own schedule.
During nesting season, one-way doors are off the table. A Naperville provider will set cage traps at the entry hole or hand-remove the young and reunite them with the mother outside.
There is no Naperville-specific squirrel infestation rate published by any agency, and this page does not invent one; what exists for Naperville readers is national and regional survey data plus published pricing benchmarks, summarized below with their limits stated plainly. Two hundred to $600 is Fixr's January 2025 U.S. publisher estimate for installing a one-way exclusion door that lets squirrels leave but not return; it is not an observed bill, and local quotes vary. If a trapper only needs to move one animal, Fixr's January 2025 U.S. publisher estimate of $75 to $125 for relocation shows how modest the job can be; it is an estimate, not a measured price, and some states restrict where squirrels may be released. Before comparing Naperville quotes, note this: for a homeowner, it helps to know that a few neighbors actively want more squirrels: 8.4% of metro-area residents reporting squirrels or chipmunks nearby said so in Puri and colleagues' 2022 survey (published 2024), which measured neighborhood attitudes, not infestations. Naperville households fit the wider pattern here: just 9.3% of residents who reported squirrels or chipmunks nearby wanted a large decrease in their numbers, according to Puri and colleagues' 2022 survey of 1,006 people in a southeastern U.S. metro area (published 2024), a neighborhood-attitude figure, not an infestation rate. What the research adds for Naperville: in HomeTeam Pest Defense's March 2022 online survey of U.S. homeowners ages 25 to 75, 37% reported trying DIY pest control; because the sponsor sells professional service and the sample was undisclosed, treat the figure as self-reported, not a national estimate. Because every figure above has a stated population and date, you can cite it when comparing Naperville providers; what none of them can tell you is what your specific Naperville property needs, and that still takes an on-site inspection.
Some Naperville homeowners try to seal holes themselves and end up locking a squirrel inside. If you hear frantic activity after a DIY patch, call a professional in Naperville immediately, because a trapped squirrel will chew through drywall to get out. Many states require a wildlife control license to trap squirrels for a fee on someone else's property.
The biggest DIY mistake in Naperville is sealing the hole while squirrels are inside. It happens constantly in Naperville, and the result is a chewed ceiling or a dead animal in the wall. A Naperville provider confirms the attic is empty before closing anything. Tree branches trimmed back six to eight feet from the roof remove most squirrel launching points.
Every Naperville property sits in the same humid continental climate, but squirrel pressure still varies block by block with drainage, landscaping, and the age of the house. Activity typically peaks during late winter/spring and late summer/fall (two breeding seasons). None of that replaces an on-site inspection of your Naperville property; it only explains why timing and thoroughness matter here.
