Advertisement Hey all, I've lost most of my Dubia colony to some sort of small parasitic fly (likely Phorid flies). I tried cleaning and moving to a fresh container, but they are back again and munching through my remaining roaches. I'm afraid I'm going to have to scrap this colony and start over. The local pet store owner has had similar problems and suggested putting paper towels across the tops of the containers under the lid. Unfortunately, that won't work well with a container large enough for a decent colony, and I'd prefer a more durable and permanent filter solution. Does anyone have any suggestions for an air tight container and filter I can use to keep the suckers out of my new colony? I'm US based, so anything sourced through Walmart, Amazon, or Hobby Lobby is a plus!
