Frequently asked questions

Grey squirrels don’t attack humans, but they can bite if they feel cornered. Its real danger is structural: gnawed cables, soiled insulation and the risk of fire make it a serious nuisance not to be overlooked.

The most common clues are running noises in the attic in the morning, loose soffits or wood shavings in the attic. An inspection of the perimeter of the roof can usually locate the point of entry.

It is possible to install capture traps yourself without injury, but recapture is not recommended without experience. A professional exterminator will be able to identify all entrances, install traps in the right places and seal access once the animal has been removed.
