Evidence check: squirrel encounters, DIY attempts and professional help in Berwyn
Berwyn, Illinois homeowners often ask whether their squirrel problem is unusual and whether the price they were quoted is normal, and while public research cannot answer either question for one Berwyn house, it does set expectations. 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. Most neighbors like squirrels just as they are, which matters if you are planning removal: 63.5% of metro-area residents reporting squirrels or chipmunks nearby preferred no change, per Puri and colleagues' 2022 survey (1,006 respondents, published 2024) of neighborhood attitudes, not of infested homes. Worth knowing before you call anyone in Berwyn: Puri and colleagues' 2022 survey of 1,006 residents of one southeastern U.S. metro area, published in 2024, found that among people with squirrels or chipmunks nearby (the two were combined), only 9.3% preferred a large decrease; the figure describes opinion, not squirrels in buildings. Before comparing Berwyn quotes, note this: in the 2022 wildlife-perceptions survey by Puri and colleagues (1,006 residents of a southeastern U.S. metro area, published in People and Nature in 2024), 15.2% of respondents with squirrels or chipmunks nearby preferred a small decrease, an attitude measure and not an infestation finding. One figure Berwyn homeowners tend to underestimate: about 30% of respondents reported trying home remedies against household pests in ConsumerAffairs' February 2024 survey of 2,000 U.S. respondents, a self-reported poll covering pests and mold together that offers general consumer context rather than an infestation rate for any single pest. None of these sources surveyed Berwyn specifically, so read them as national and regional context; the local facts that matter most are the ones an inspector documents at your Berwyn property, meaning where activity is, what is attracting it and how it is getting in.
