Great info.
Getting rid of the itching after you kill them is the 2nd battle.
Dish washing liquid applied to the itching area will bring near immediate relief.
Apply it and rub it in.
It will foam up a little bit,but just let it dry.
It works on other itching as well.
If you don't like the idea of using dish washing liquid try your favorite soap or shampoo.
LAVA Soap works too.
Vicks Vapor Rub worked good too in my early stages of Scabies,when i was desperately trying different stuff for the itching.
