The warm, humid weather of West Oak, GA attracts bats, which nest in attics, hollow walls, sheds, and barns. While the flying pests reduce the mosquito population in the area by preying on the insects, their presence also creates health risks for humans. Bat urine and droppings have a strong odor and contribute to the spread of histoplasmosis. The temperate climate of West Oak also appeals to squirrels and roof rats. Both pests are known to dig in yards, short powerlines by gnawing on wires, and build nests in attics and crawl spaces. In addition to property damage, roof rats carry several diseases, including leptospirosis and food poisoning.
