The two types of squirrels I am familiar with are gray and red. Around here, we see gray squirrels Gray Squirrels are bigger than red ones. They also can travel at seems to be the speed of light. Red Squirrels, travel at the speed of a turtle.
Squirrels are cute. They don’t like you bothering them.
Gray squirrels can be destructive. If one or more gets into an attic of a house, they can cause major damage. Getting them out of there is a job for a pest control professional. It isn’t easy. They can have different access points and it is frustrating, to put it mildly.
I found two different types of red squirrel pictures. The North American has little rounded ears. The Eurasian, don’t quote me on that name, has a tuft between his or her ears.
