My blizzard corn had mites and so I cleaned his rubbermaid house and washed it. Then sprayed it with lice bedding spray from walmart which I have used before with my boas. It has the same ingredients as provent-a-mite. I sprayed the entire cage with it and let it air for about 30 to 40 minutes I put him back in. WHen I went to check on him last night. He was kind of writhing around and acting very weird sort of twitching. I could tell something was very wrong and knew then he was probably not going to make it. It had to be from the chemical. Did I not let it air long enough or did I use too much I don't want this to happen in the future.
