My DCs think I am mad. Or super tough.
I stopped doing this for a few years when there was a spate of black widow 🕷 spiders riding into U.K. on bananas. But have started again. I grab them in my hand and throw them out nearest window or door. So much easier than the ' trap into a plastic cup with cardboard underneath'
method. When you actually might then drop them and have to spend at least half an hour trying to catch the flighty things or lie that you killed them (rarely kill a spider, I can't do it) .
Not beetles. Beetles are scary.
... But spiders ... meh.
Not big spiders mind. Just spiders without beetle sized bodies.
My cousin threatens to burn her house down (possibly regularly) when she finds a spider. 
What crazy bravery parental (or other) do you MNers do?
