I had a close call one time. There was this web emanating from the handle on my garage door and a little spider in the middle I had never seen before. But I knew we only had two types of venomous spiders, and out of those two the widow is the only deadly one. And this was obviously neither.
Curious, I strummed the web a little to get the spider to turn so I could see it better. Instantly upon feeling the web I knew exactly what it was. Sure enough, I looked under the garage door handle and there was a FAT black widow up under there. Turns out the little spider in the middle was a male black widow, which apparently looks nothing like the female and isn't really venomous. So yea, I won't be making that mistake again...
I did! There are still scorch marks on the garage door! LMAO
Little bugger had barricaded itself to where I couldn't smash it. Let's just say it involved an aerosol can and a lighter...
