Oh snap, we are beyond sensitive it turns out. We get a touch from a thing that touched a thing that touched something else that.... like 7 transfers later we get hives. The real wonder is fast orange by Permatex the mechanic soap with pumice. It is the only thing we find that removes it besides detergent washing. Also, it’s cheap at Walmart. We have a gallon at every sink. We was whenever we were outside. It’s amazing. So wash clothes in hot water and detergent in washer, kids with orange soap, alcohol everything they may have touched. Make sure you wash shoes and shoe laces with detergent too. Outdoors it fades from surfaces in months. Indoors it can exist for 5 years. We are still getting hits from boxes that were on the floor briefly last year when we move them. The bentonite in a dose or two will dry up the rashes and they will stop hurting in a day, gone in 3 for us. We had some for 6 months and while it’s not supposed to be able to spread internally, for us it does. Some are immune, I used to be as a kid, not now. It’s difficult to find info on it, I have spent many many hours. I hope it helps you.
