Most people aren’t aware of it, but there are several different species of squirrels living throughout North America. The most common types of squirrels found in the U.S. are Black-tailed, Fox, Long-Tailed, and Eastern Gray Squirrels. While these four species pose little risk to humans, others such as Red Squirrels, Hairy-Nosed, and Flying Squirrels are known to carry diseases such as rabies. If you find yourself in close proximity to one of these animals, it’s highly recommended that you wear protective clothing such as long pants, closed-toe shoes, and long sleeves while outdoors.
