I am in desperate need of help!

I acquired a crested gecko three weeks ago. Tonight I decided it was time for a 50% substrate change and a wipe down of the decorations (I have spot cleaned before this point.) I have been using straight cypress bedding, and haven't seen any signs of mold in it.

Or so I thought. I picked up a piece of driftwood I had on the floor of the tank tonight and the underside of the wood was INFESTED! It has three things on it that are visible to the naked eye...

A. a white, fluffy mold like the kind you typically see on wet firewood

B. a black mold that looks like this:



C. a silver, tiny bug that looks like it may have wings

HELP!!!

I am seriously worried that the black mold is toxic, and that the mites are going to hurt the gecko.

I have...

1. Checked the gecko for mites under good light, including in/around ears and eyes and mouth. No sign of bugs.

2. Pulled 90% of the cypress out, including everything on the side of the terrarium with the wood, and threw it out

3. Threw out the infested wood.

4. Checked other decorations for issues - no sign

What else can I do?
