What to check and record
- Photograph from an accessible clean area without touching or disturbing waste.
- Record any animal actually seen, the date, and its route. Keep sounds and assumptions separate from sightings.
- Do not sweep or vacuum suspected rodent waste. Follow CDC cleanup guidance or arrange professional help.
Compare the alternatives
Rats and squirrels may both use buildings, so an attic location is not decisive.
Tree squirrels can enter attics or garages and damage building materials. Gnawing still does not establish which rodent is present.
A roof sighting and attic waste need a connection
Seeing a squirrel on the roof does not prove it deposited material inside. Record the animal’s actual route and whether you saw it enter an opening. Keep a separate note for sounds, waste, and building damage. This prevents an inspector from inheriting a confident squirrel diagnosis when the indoor animal is still unknown.
Observe exterior access from the ground
Use a safe ground-level view to photograph a suspected opening and its position on the building. Do not climb to follow the animal or reach into a cavity. Note whether the opening was merely present or used while you watched. The distinction helps a wildlife professional decide what needs inspection without treating every roof gap as a confirmed entrance.
Prepare for occupancy and exclusion questions
Ask the wildlife professional to determine what animal is present, whether the space is occupied, and how the plan will account for animals inside. Do not seal a suspected active opening in advance. Give the professional any prior exclusion work or repair history. The waste identification, animal-removal plan, and building repair may require different evidence and should be explained separately.
Keep cleanup scope in the report
Describe the accessible affected area and whether insulation, stored belongings, or other materials appear involved. Do not disturb waste to estimate its depth. Ask who will assess cleanup and which areas were not examined. Photographs can document a concern, but they cannot certify a contaminated attic as safe or establish the animal solely from pellet appearance.
Keep the context with the clue
Record the date, exact location, visible features, and what remains uncertain. Bring the record to a qualified identifier.
Add this finding to your evidence log →Common questions
Can an online poop chart confirm squirrels?
No. Such charts may suggest possibilities, but overlapping appearance and missing context make species confirmation unreliable.
Does daytime noise confirm squirrels?
No. Timing can be useful context, but a sound alone does not identify an animal. Record it as a sound observation and seek confirmation from direct evidence.
Should I close the hole as soon as I find it?
Have occupancy and the exclusion plan assessed first. A suspected access point may still serve animals inside, and a photograph cannot resolve that question.
