A few weeks ago I had a mite problem and my fruit-fly cultures were not producing any flies, so I had to get rid of all the cultures I had started. so I ordered a couple of new cultures to start over, the cultures were 4 days old when I received them now they are 8 days old and they have a ton of larvae and some have begun to pupae or what ever you call it and they are a light color. but no new flies yet and aren't the pupae suppose to be a dark color b4 the flies emerge? and the starter flies I had to feed them to my frogs because they had to wait for the flies to arrive (4 days). Also the new cultures are kept in a different part of my house and I cleaned with bleach and water the place I used to keep them at. By the way they are Melanogaster cultures.
Please Help if you can
Thanks Dave
