I've not encountered snakes in the house but garters are fairly docile. They will attempt to bite but have no venom. If you can isolate the critter and toss a large towel on it, you've got a good chance at being able to safely pick it up without injuring it. I'll be anxious to hear Marks advice.
Apparently a garter snake has found its way into our basement/laundry area. I don't care that much but my wife is terrified of snakes. There's all kinds of stuff down here so he could escape and hide forever.
Are there snake traps? I'll probably be heading to the hardware store to see if I can find something. Until the snake is captured I don't think my wife will be able to do laundry ever again. All reasonable ideas welcome.
