Sounds like you both had some nasty experiences. I'm glad that, so far, I've only heard about this kind of stuff -- and not found one myself. Whenever I inspect the dryer vent cap, I always tap on it first just in case. While running into a snake is pretty rare, it's not uncommon for mud daubers to build nests inside if the cap is blocked open by lint. I'm not a fan of getting stung, either. Thanks for sharing your stories -- Gabe

Ick!
A few years ago, one crawled up into our water pump. It was wrapped around the area where the warmed air goes out. It had been dead for awhile before I found it, and we had to pick out the goo, piece by piece.

We found a small grass snake in our clothes dryer once. He had made it all the way to the inside of the door and was well done when we found him. Needless to say we rewashed that load of clothes.
