@bagelface unless you live somewhere that has truly venomous indoor spiders, or where venomous spiders and scorpions are a REAL problem, you are worrying yourself for no good reason. Those places would be the tropics.
I live in the Midwest, which is at the extreme northern edge of the brown recluse territory, and I don’t even think any of the virulent black widows are found around here. I’ve never seen one in the five decades I’ve been alive, so I doubt they are common here at all. The dangerous spiders live in the more southern states of the US, except for the hobo spider which lives in the northwest, but they rarely come indoors, simply because there isn’t a good food source for outdoor spiders indoors. When I say dangeorus, I mean they might bite you, but it won’t kill you, and at most, it will make you ill. Even the tarantula, which is a pretty big spider, has weak venom. It is the hair on its abdomen which it will flick at you with its hind legs, is more troublesome than a bite.
This is going to freak you out, but it shouldn’t. In the US, there are approximately 30 species of indoor house spiders. While they have venom with which to kill their prey, their venom is quite weak, and besides, despite the belief to the contrary, house spiders do not bite humans. I have plenty of spiders in my house (they serve a valuable purpose) and have NEVER been bitten. I see them more often than most people simply because I like spiders and look for them. I handle them rather often, and they see me as simply furniture. They are unaware of my existence as a living being. Indoor spiders pose no threat to humans at all.
What you should be worried about is other people; they are twenty times more dangerous than the occasional spider you may come across.
