Most spiders here (Texas for people other than DJ) are harmless even if they look terrifying. There are just two really dangerous ones, and unfortunately those two can really do some damage. One is the black widow, but we really don’t encounter them often since they are not that common and they are pretty easy to spot as well as identify. I’ve only seen one in my whole life.
The other spider is the one that causes most problems, which is the brown recluse. They aren’t that noticeable or large and they tend to stay underneath things so you don’t see them until it’s too late. If they do bite it is very painful and isn’t usually fatal, but will at least require an emergency room visit and a lot of care. If you don’t treat the bite right away, you can lose the affected limb. As the name implies, though, they are “reclusive” and they mostly live outdoors in piles of firewood or lumber. If you wear heavy gloves or don’t handle things like that, it’s not so likely that you’d ever be bitten.
The rest of the Texas spiders are not a big deal even though I try to avoid touching them. I’m more scared of crickets, which is rather silly, but true.
