A field template you can copy onto one page
Set up the page before the inspector arrives. Across the top: date, address, weather, provider name and technician name. Then five columns: location, evidence, size or extent, photo number, and recommendation. Leave a wide margin for the inspector's comments. As you walk, fill one row per finding. A row might read: 'NE corner, garage roof to main wall / chewed wood, grease marks / 4 x 6 inches / photos 7 and 8 / seal with metal flashing after one-way door.' Keep the language short. You are capturing facts, not writing prose. When you reach the attic, switch to a rough sketch. Draw the attic outline, mark the hatch, and note where droppings, trails, nesting material and damage are. Estimate square footage of contaminated insulation by pacing it if the attic is floored, or by comparing to joist spacing if it is not. Note where daylight shows through. After the walk, add a section for open questions. Common ones: is an animal inside right now, are there likely young, is the chimney capped, are any vents unscreened, is there a second structure to check. Ask the inspector to answer each before they leave. Finish with a short summary in your own words: what animal, how many entry points, what damage, what they recommend, what it would cost. If any of those is unclear, you have found the questions to ask when the written proposal arrives.
Separating evidence from interpretation
Wildlife work depends on reading indirect signs. Almost nobody sees the raccoon walk into the soffit. The inspector sees a torn panel, a smear of dirt, and hears your description of thumping at 9 pm, then concludes raccoon. That conclusion is probably right. But the record should show the chain. Write evidence as things a camera could capture: 'hole 4 inches round in gable vent screen, edges chewed, wood splinters below on ground.' Write interpretation as a separate line: 'inspector says squirrel, based on hole size and daytime sounds.' If the inspector adds a confidence level, record it. 'Probably' and 'definitely' are different words and they should stay different on paper. This matters in three later moments. First, when a second provider reads your notes, they can form their own view instead of inheriting a conclusion. Second, if the exclusion work does not stop the activity, you can go back to the evidence and ask what was missed. Third, if there is a dispute about whether a repair was needed, the record shows what was actually observed. Ask the inspector directly: which of these findings are you certain about, and which are your best judgment? A good provider answers easily and often volunteers the uncertain items. Write the answer down next to each finding.
Using the record after the inspection
The finished record has three jobs. The first is quote comparison. Send the same one-page summary to each provider you ask for an estimate, and ask them to price against the numbered entry points. When quotes come back, you can see whether each one addresses every opening, and whether they differ on materials, one-way door placement or cleanup scope. A quote that skips entry point 4 without explanation needs a phone call. The second job is verification. When the exclusion crew finishes, walk the numbered list with the technician. Look at each location, photograph the repair, and note the material used. If the repair at point 2 is expanding foam where the quote said metal flashing, that is the moment to raise it. Sign off only when every item is either repaired or explicitly marked as not needed, with a reason. The third job is long-term monitoring. Six months later, if you hear scratching again, open the record. Check whether the new sound is near an old entry point. Re-inspect those spots first. If the repairs are intact and the animal found a new way in, that is useful information for the warranty conversation, and it tells the provider where not to waste time. Store the record with photos in one dated folder. Add every quote, invoice, warranty document and follow-up note to the same folder. That folder becomes the history of the building's wildlife problem, and it is the single most useful thing you can hand a provider on the day they arrive.
Wildlife problems by the numbers
Before you compare providers, it helps to know what independent surveys and published cost guides actually report about wildlife problems in U.S. homes. None of the figures below come from this site's own customers; each carries its source, date and population so you can weigh it yourself. Among affected households in the Illinois Natural History Survey's (INHS) July to October 2012 survey of homeowners in the greater metropolitan area of northeastern Illinois (n=859, reported 2013), 44.6% listed landscaping damage, one of several damage types they could select. Animals inside the structure are the cases that escalate: 18.7% of the 859 wildlife-affected northeastern Illinois households in the Illinois Natural History Survey's (INHS) 2012 survey (reported 2013) had an occupied attic, chimney or home, a regional multi-select figure. Among affected households in the Illinois Natural History Survey's (INHS) July to October 2012 survey of homeowners in the greater metropolitan area of northeastern Illinois (n=859, reported 2013), 32.0% listed animals occupying a porch or deck, one of several damage types they could select. Thirteen point seven percent of the 518 northeastern Illinois homeowners who took action against wildlife in the Illinois Natural History Survey's (INHS) 2012 survey, reported in 2013, hired a private removal service; respondents could name several methods, and the figure is regional, not national. For a property manager, the sobering number is that pests can end a tenancy: 7% of respondents in ConsumerAffairs' February 2024 survey of 2,000 U.S. respondents reported permanently leaving a home over pests, a self-reported finding from a mixed pest-and-mold survey, not an infestation rate. If one number should shape your next step, it is how often do-it-yourself attempts fall short. That is not an argument against trying, but it is a reason to set a deadline and call a professional if the problem persists past it.
