Picture this: You're returning home at the end of a long day, when suddenly you see a snake hanging down from a gutter, its head mere feet away from the front door. Yikes! While a gutter-dwelling snake may sound like the stuff of nightmares, it can be a reality in some parts of the country, particularly in summer. Why? Gutters provide snakes and other reptiles with virtually all they need to survive and thrive, including warmth, shade, and easy access to prey. If you spot a snake in the gutter but don't recognize the species—if you can't say whether it's dangerous or not—then exercise extreme caution. Call in an expert, whether a private pest-management company or the municipal animal control department.
