Pets hate the smell and are more likely to stay away.
Spray screens with orange juice to keep pets from damaging them. Sprinkle chamomile leaves in house or under blankets. To keep them away from electrical cords, rub a perfumed bar of dry soap down the length of the cord. They'll stop chewing once they've had a taste of suds. Use an old shower curtain with a hole cut in the top as a poncho to protect clothes against a pet's shakes when giving it a bath.
