How to Detect Raccoons in the Backyard In residential lawns, raccoons easily construct dens in tree hollows, under porches and decks, and in rarely used sheds where they then feed on fruits, nuts, insects, outdoor pet food, and garbage. Though they are nocturnal and mostly solitary creatures, the pests are fairly destructive and give property owners many opportunities to discover their obtrusive presence. For instance, raccoons are messy eaters, and individuals may wake up to trash strewn about lawns. They also rip up sod searching for grub, steal siding off homes, and scratch up ornamental trees and fences. Finally, residents may be alerted to infestations of raccoons in backyards by the presence of their distinctive tracks. Negative Effects of Raccoons in the Backyard Along with the superficial and aesthetically displeasing damages they cause, raccoons in the backyard bring about more serious structural destruction and spread diseases. The pests set up latrines nearby their nests where they dispose of waste. Their excrement often contains a parasite known as raccoon roundworm, which can be deadly to humans. Additionally, raccoon presence also contributes to the spread of rabies and leptospirosis. Having raccoons in the backyard is also one step away from dealing with infestations inside the house. Given the onset of unfavorable weather, raccoons will find a way inside and cause even more destruction. Removal Raccoons, especially those affected by diseases, become territorial and aggressive with little prompting. The common property owner is ill-equipped to remove infestations without professional help. Amateur attempts to get rid of raccoons often result in injury or disease transmission. As such, individuals dealing with raccoons in their backyards should contact wildlife removal services.
