aw, that bongo playing spider is cute. as much as i respect spiders for what they do to keep the insect world in check, if i find a spider in my house, its gonna go squish because it could get my dog, Mojo. and my dog is more important than a spider.
Or you could always just scoop it up & toss the spider outside. You'll get the same result, but without choosing to take a life or have a mess to clean up. I've found that Fererro Roche boxes work great for this, as 99% of the time you can trick em into running inside, simply by placing the box sideways & moving the lid close to em from the other side.
they also eat they're mates...As a man I don't envy them websters of the XY chromosome... plus I'm sure some spiders EAT they're young...or get eaten by them.
It's how nature works, gotta feed your young somehow. I'm sure those are harmless to her though, they're probably too weak to cause her any harm at that point.
Spider Myths: Home Also can't fault spiders for things like filial cannibalism (eating babies) when plenty of other animals (including primates) do it, too.
