I'm going to go with wet Sani-chips. I just had my first experience with wood mites and it's caused a major freak out but I do think I've annihilated every last creepy crawly in my house. I've spent countless hours going over every snake with a magnifying glass and only found about five. They are all white and smaller than a pin hole.
The problem was only in my hatchling quarantine rack and my collection hatchling racks, which are the only tubs I use SaniChips in. They are also low ventilation and stay extra humid which I'm sure helps break down the wood quicker. I've learned this things love decaying wood.
I've blasted everything with PAM and have another three cans on the way. I also gave them all a soap bath and soak. So far, I haven't seen anymore. This was my first year with SaniChips and it's been great over changing paper towels daily, but I don't think I will continue using it. I have never noticed wood mites in the shredded TekLad but it's also used in a lower humidity environment than the hatchlings.
