Most squirrel advice online repeats the same unsourced claims, so for Janesville homeowners the statements below are tied to specific surveys, studies and published cost guides, and each one says what it does and does not prove for a Janesville property. A striking 89.1% of the 1,006 residents of a southeastern U.S. metro area surveyed by Puri and colleagues in 2022 (published 2024) reported squirrels or chipmunks in their neighborhood, the two animals having been combined; this counts sightings, not animals in attics. 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. For Janesville, Wisconsin the relevant figure is this: A homeowner budgeting for squirrels in the attic can use $350 as a rough anchor, which is Fixr's January 2025 U.S. publisher estimate for a typical project, not a measured bill; actual quotes depend on access, severity and local labor rates. One figure Janesville homeowners tend to underestimate: Fixr's January 2025 U.S. squirrel-removal cost guide estimates attic removal at $300 to $600, matching its garage figure; both are publisher estimates rather than verified transaction prices or current local quotes. Homeowners in Janesville ask about this often: in ConsumerAffairs' February 2024 survey of 2,000 U.S. respondents about home infestations, which mixed pest and mold questions and relied on self-reports, 17% said they had done nothing about their pest problems, a general consumer figure and not a per-pest statistic. None of these sources surveyed Janesville specifically, so read them as national and regional context; the local facts that matter most are the ones an inspector documents at your Janesville property, meaning where activity is, what is attracting it and how it is getting in.
