“That will give you a 50/50 chance for payback because half the population doesn’t react to poison ivy.”
Well,,,, my neighbor’s kid is now covered in Calamine Lotion. And he has no clue why I told him he won’t be cutting my grass anymore. I’ll take 50/50 over the odds of actually catching someone!
LOL I like the idea of skunk gel or skunk spray. Add some capsicum to that. You could use an expired pepper spray canister. Capsaicin oleum is a resin that is almost impossible to wash off. I don't know of anyone who is immune to pepper or can stand skunk.
