So what i've done is sprayed a tiny bit on the glass bottom, then put in the substrate(moistened it with water) and sprayed a tiny bit again, then i put in all the furnishings and sprayed the walls and put a little in the air above the open tank like if you were spraying febreeze. Is this safe or should i not put him back in that tank? Btw i didn't have the water bowl in when i said the furnishings. Give me your method and tell me if mine is ok. and btw should i leave the residue on the glass, it looks like crap but if thats what keeps the mites away ill keep it, but my snake might rub up on it.
