Raccoons are easily frightened away from a trash can or garden by humans, raccoons can be fierce fighters when cornered; in such instances, they have been known to inflict fatal wounds on even relatively large dogs. Therefore, care should be taken when attempting to control these common vertebrate pests.
Raccoon, like skunks and armadillos, ca be destructive to lawns and other grounds landscaped in cultured turf grass due to a propensity for “grubbing” behavior, as they dig for scarab beetle larvae on which to feed.
Raccoons often gain access to attics, basements, and crawlspaces by forcing open loose or broken vent covers, louvres, windows, and carpentry. Female raccoons readily invade attics or uncapped chimney flues and occupy the smoke shelf above the damper door to birth and wean their litters of pups. Since raccoons often are infested with ticks and various fleas, including cat fleas, human occupants and their animals are readily infested secondarily by the introduction of these ectoparasites via fireplace hearths and attic entrances.
Raccoon feces accumulate in the above-mentioned areas, thereby giving rise to odour and secondary pest problems, as well as serving as a potential source of raccoon roundworm infection. Raccoons have been implicated in several other infectious diseases transmissible to humans including leptospirosis, Chagas’ disease, tularemia, and, most notably, rabies.
