I woke up with three spider bites on my arm this week. I put a bunch of sticky traps under my bed, spiders - you've been warned.
Spiders don't bite you while you are sleeping - they have no reason to, except for self-defense. As mentioned already, venom is biologically expensive, so it is only used when absolutely necessary, and only sparingly. If a spider were to bite you in your sleep, it would most likely be a single bite, not multiple.
My cousins would wake up with welts/bites from mites, or fleas, and would constantly blame spiders. No matter how often I tried to explain why it wasn't spiders, they wouldn't hear it - they just hated spiders, and all manner of creepy-crawlies.
Hopefully you don't have bedbugs, because if you do....well, I wouldn't wish that on my worst enemy.
Good to see this thread alive again! GAF, can you help me name my spiders? I have two. one is a Metallic pink toe, and the other is a Honduran curly hair.
Grown, they will look like this respectively;
Some features. The first is a tree dwelling spider. It stays in it's web near the top of the container. The other loves to dig. Both sexes are unknown, at this time. And thanks for the kind words guys! Spiders are the shit!
One should be named "Horace," and the other "Greeley."
