Well, I bathed everyone a few days ago, and while each snake was bathing, I stripped each tank and sprayed 100% rubbing alcohol into it, scrubbed, and rinsed well with a hose. Today I tried soaking the boa or awhile and came up with no floating things in the water. I don't want to get too happy, but I hopefully have done a number on the tick population, if not killed it all off. I'm going to soak the big guy, Octavia, and Goblin tonight to see what comes of it. Please wish me luck!
