When young squirrels aren't present, trees near the home are trimmed back so that branches are at least 10 feet away from the roof, and the animal's entrances are located and sealed to prevent further entrance. Deterrents are used to encourage the squirrels to move.
When young squirrels are present, the squirrels should not be prohibited from entering the home. After several weeks, the squirrels vacate the space, and the animal's entrances into the home are sealed.
Loud noises, such as a radio played in the attic at night, and strong smells, such as bowls of apple cider vinegar placed in the affected area, encourage the squirrels to move. Do not use toxic substances like ammonia to repel the squirrels.
