I was recently at the store and was checking out and noticed the produce girl was putting apples into a bin. I saw these gray flats, that kind of look like egg flats. I immediately asked if i could have them, and of course she said yes. I like the apple flats better because no risk of contamination from eggs. Plus they seem more sturdy. I just thought i would put this out there just in case anyone needed some flats for a dubia or cricket colony.
That would possibly be a good idea ! I guess the only thing to wonder about is whether or not there'd be any residue of pesticides. Sometimes I use the cardboard holders that come with a fast food drink order or similar thing....though I don't eat much from that type of place.
