“All spiders bite!” No. Most British spiders can’t even pierce human skin. Their fangs are too tiny, like cute little needles that can’t reach your nerves.
“They crawl into your mouth while you sleep!” That’s a myth someone invented to sell mosquito nets. Spiders avoid warm, moving, breathing things. Your mouth is a sauna of doom to them. (Also, ew.)
“The UK has black widows!” We don’t. The noble false widow gets confused with one, but it’s like confusing a squirt gun with a fire hose. They’re not in the same league.
