Snakes are reptiles. There are 14 species of snakes listed for Connecticut. Only 2 are venomous. Connecticut snakes are often maligned but do not tend to be aggressive. If you leave them alone, they are going to leave you alone. Our snakes, including the 2 vipers, only bite if handled or threatened.
Snakes are actually helpful, eating many of the small rodents that cause trouble and thus keeping their population at a manageable level.
