To identify venomous snakes quickly, without going too close, it helps to remember that they are fatter than harmless snakes, and usually taper at the neck and tail, while the non-poisonous varieties tend to be thinner and evenly shaped from head to toe, like a garden hose. Venomous snakes have a skinny neck and a diamond-shaped head, like a spade. They also tend to be more colorful, and aggressive. To play it safe, never provoke any snake; leave the area as fast as you can.

Hi Judy:
Don't know how your question got in the Cars and Trucks section, but had to reply anyway.
Can you give us a hint of your general location, and the kind of snakes you are dealing with?
If the snakes are not presenting a hazard to people they actually may be beneficial by eating rodents or other pests.
My suggestion would be to contact the local Government Conservation Officer for appropriate information.
Please reply as a comment to this post to let us know how it is resolved.
Cheers.

Hi Connie

Sounds like you're describing the common garter snake.
Harmless to humans.

you most likely have a cloged a/c condensation drain line, this shouldn't be to hard to fix, you just need to find where the hose comes through the firewall and clear it with ether a small pipe snake or (this works best) a gun snake.
