While a comprehensive approach is the best way to prevent complications from intruding wildlife
, there are several specific species that you should be on the lookout for. Eighty percent of animal break-ins are carried out by three mischievous rodents: mice, rats, and squirrels. These thieves love to hide in attics and ransack your food supplies. Like many pests, their presence poses a severe health concern. Their urine and droppings contain harmful bacteria and sometimes parasites. They also harbor dangerous diseases, such as rabies, salmonella, and even, on rare occasions, the bubonic plague. Among the more surprising visitors are snakes looking for a place to hibernate.
