One of the easiest ways to confirm if you have a raccoon in your roof is by doing a visual inspection. This should be done by a pest control service technician who has the training and tools required to enter and exit safely from the roof line. When, visually, no raccoon can be spotted, there always tell-tale signs such as a latrine that can help determine the presence of raccoons. Placing a pest cam in the roof void or the use of thermal cameras are other tools that help confirm the presence of raccoons.
