Sure, it just sits in the web, waiting for something to land. Until you walk through its web one morning and it finds itself on your face.... aaaaaaggghhhhhh!!!!!!!!!!!!!!!

I've never heard of anyone using shotguns on a spider, but I do know someone who dealt with a seven-foot brown snake (quite lethal and aggressive) that was draped over the bushes in their garden by blasting it in two with a 12-gauge.

I think this was actually a good technique, because (a) it worked and (b) most people who get bitten by snakes got bitten because they were attacking the snake with something silly like a stick or a shovel. Don't take a stick to a fang/gun-fight.

That said, leaving them alone usually works.
