I dont know whats going on but my dubia roaches keep dying. I own like 15 and some keep randomly dying. I give them water crystals for water, I usually feed them oranges and some carrots (we also just bought them some potatoes), they have egg crates, I have a heat mat with a thermometer and I set it to go to 87 degrees, I have a cup of water with a lid with holes for humidity, I havent seen any ants and how do I check them for mites?, their container is clear but we glued some curtains around it so that its dark for them, I also have a window screen for a lid. I think they breed because I can see the egg sacks but the females keep dropping them, also we just got them about 3-4 weeks ago. please help idk whats going on thank you!
