Yeah. I got it online with the nymphs. A while ago I went through the trouble of creating my own batches of flies but then they began to fly around my apartment. I could not have that issue here. So, i moved on too crickets as I only had all L3-5 and adults. Now that i have more nymphs I'm back with the stinking flies again. When I was making my own culture I came across university website which used mashed potatoes, sugar andyeast only. Before that I used bananas ,oatmeal, and i believe yeast grains. So, how are they kept from flying anyway? Is this some genetic procedure?
As long as the mites won't harm the mantids I'll just stick with it until i get a fresh batch.
Regards!!
