You need to mention what you're using for media, and how you're preparing it. Also mention if you include any material for pupae staging.
One quick helpful hint: use vinegar with your water and media. I believe anything from 10 to 30% is about right. Some might actually use a little more. I use around 10% (to water).
I had minor mold problems before... and it may/may not be related to vinegar, but I've had no problems since.
