What if we swallow a spider?

"Not all spiders can attack you with toxins - this means you will feel uncomfortable if you accidentally let them slip through your nose or eat - but all of these animals have enough venom. to kill small prey, " added Buddle.

Some spider species are dangerous to humans, including the black widow spider (Black widow spider) and the brown recluse spider.

If a spider is in your mouth while you're sleeping, it may just accidentally "slip" into it, unless you've "swallowed" so many bugs that this animal feels they'll have a Delicious meals when you get into your mouth!
