I'm an arachnophobe for sure. I don't take chances with the fuckers.
Why is it so beneficial? Keneo answered that.
Next time I'll try to let it be. Thanks for the information.
They eat all of the things you hate more than that spider. Including other types of spider.
Also, leave Jumping spiders alone. If you find them in your house there is something in there you don't want to be there and they will kill it and eat it for you and you will never know it was there. They are "assassin bugs" and make for good house mates. Also, they are kind of cute.
A lot of spiders still freak me out a bit, but jumping spiders are just adorable to me, now that I understand them better.
Mainly for the amount of flying insects they consume. They'll catch bugs up to the size of grasshoppers, but more often they catch flies and mosquitoes which can carry diseases to humans. The same is also true of bats.
