Okay, so last week my mother in law sent me some flowers for the house, which unfortunately had fungus gnats on them and now I've noticed I have fungus gnats from them in my snake tank. I don't think it's a huge problem, but since my snake is in the process of shedding I don't want to stress her out. Do you think it's okay to wait until she's done shedding to remove all the substrate/bleach tank out/ apply fresh beddin or should I do it all right now? The earliest I would get it done would be tomorrow. I have not found anything on the web saying that fungus gnats are harmful, but I figured I should ask.
Also, what is a another good type of bedding for her? I really like the 'natural' looking stuff so any ideas?

Thanks.
