The research on raccoons in U.S. homes, and what it means in Somerville
Most raccoon advice online repeats the same unsourced claims, so for Somerville 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 Somerville property. If you have seen a raccoon on your street, you have plenty of company: 51% of metro-area residents in Puri and colleagues' 2022 survey (1,006 respondents, published 2024) reported them nearby, though that is a sightings figure, not a count of raccoons in attics. Two hundred fifty to 500 dollars is HomeAdvisor's June 2026 estimate for cleaning and sanitizing after raccoon removal in the U.S., a publisher figure rather than an observed customer bill, and usually a separate line item. For Somerville, Massachusetts the relevant figure is this: for homeowners, the practical message is that few neighbors want more raccoons: 7.4% of metro-area residents reporting raccoons nearby preferred a small increase, in Puri and colleagues' 2022 survey (1,006 respondents, published 2024) of neighborhood attitudes rather than infestations. The national picture, which Somerville has no reason to escape: Puri and colleagues, who surveyed 1,006 residents of one southeastern U.S. metro area in 2022 and published in 2024, found that 46.2% of respondents with raccoons nearby preferred an unchanged population; the number describes opinion, not the share of homes with raccoons. The same question comes up in Somerville: Seventy-six percent of U.S. homeowners ages 25 to 75 in a March 2022 online survey by HomeTeam Pest Defense said they had dealt with a pest issue in the previous year, a self-reported figure from a provider-sponsored survey with an undisclosed sample size. None of these sources surveyed Somerville specifically, so read them as national and regional context; the local facts that matter most are the ones an inspector documents at your Somerville property, meaning where activity is, what is attracting it and how it is getting in.
