Thanks. I am new to the mealworm thing. I just got my worms a few days ago. I decided to try apple and pear at the same time. I put half of each in the bin on plastic lids. After two days, there are 3 times as many on the pear as are on the apple. They seem to like both, but they are absolutely devouring the pear. From the posts I've read it seems like the mealworms are a little like people: some like chocolate (pear), others prefer ice cream (apple). I probably will mostly use carrots because they sound the most trouble free, but I started them out with fruit, because I had a couple pieces I needed to get rid of.My guys love apples. They eat it fast enough that it doesn't mold. All that is left is a dry skin when they are done. I put in halves to make it easy. I put it on a plastic lid or on the paper or egg crate.
