anybody had this experience? I took some nice flat rocks from my yard, blasted them with the hose and ran them under hot (not boiling) water. Put them in my chuckwalla's cage and an hour later there are mites darting around on the rocks. I immediately took out the rocks and crushed the little red mites that I saw running up the sides of the wood cage. That was yesterday. Today, I've only seen a couple of mites. My question is - are all mites visible to the naked eye, in which case they are definitely gone? Can a few mites do any real damage? Third, will pouring boiling water over the rock kill mites?
