Ask them if they’re pregnant. Only the pregnant ones will suck your blood.
Also, they sense people via their carbon dioxide emissions. Exhales and bodily odors/off-gassing, so put up fans around you to prevent them from finding you.
Besides living in terror, you can negotiate a deal so they leave you hostages alone.
I suggest offering them a helicopter, 5k, and six CR usernames.
Actually, if you get them a mini-laptop, then they’ll be too busy on CR to notice you slowly carrying the thing outside.
Or… invite a lizard or frog to spend Shabbos with you. You won’t even have to cook anything special. They’ll devour your hostage takers.
