Will Squirrels Leave an Attic on Their Own?

Why Do Squirrels Live in Attics?
Squirrels typically make their homes in dense forests. Forks of trees and tree cavities are ideal locations for a squirrel to make a home. Up to 60 squirrels can live in a single square kilometre, so the furry residents in your area may not have enough trees to go around. Attics mirror the warmth, seclusion and comfort of a tree hollow. You’ll especially see a squirrel desperate for a safe home during nesting season. If you notice a squirrel in your attic between late March and early May, or between July and August, it’s likely a female looking for a place to raise a litter. Once a female squirrel has a litter in your attic, removal becomes more difficult. Without care, you may remove the mother and separate her from her new litter. This often dooms the babies that are too little to survive on their own. This is just another reason that it’s essential to work with a professional for humane wildlife services.How Long Can Squirrels Survive in the Attic?
