How To Tell If You Have An Animal In Your Wall. Flies often converge on dead, decomposing animals. Look at photos of raccoon feces, or squirrel feces, or rat feces, or mouse feces, or bat feces.
If you are not sure what type of animal you have in your attic, you can look around for clues. While smaller vermin like rats merely leave a stench, larger animals like opossum or raccoons, have been known to leave damp spots or stains at the site. Once you take the quiz, you can invite your friends and share your results.
If the animal is small and fast, like a rat or squirrel, you need to mount a trap on the hole right after you cut it.
Either way, the objective is to either begin collecting rent. For bigger holes, you may want to hire a general contractor to fix the hole and your roof or wall, but if you want to try fixing the hole yourself, use metal sheeting, lath screen, lath metal, cement or hardware cloth. It might sound like a light scratching or chewing sound. Stinging insects and carpenter ants need to have their nest destroyed, so first identify their access point.
