How crowded is the bin? I saw cannibalism in my discoids when it got overcrowded because there was too much competition for space/females among the males. I got a larger bin and then no more problems.
Well, if you weren't planning on cleaning it yet then there's no sense to rush it. Especially when considering moving to a larger tub, the frass will be thinner at the bottom anyway.
Wow I've been keeping Dubia for 4 years and never seen this type of aggressive behavior. There are parasites and even viruses that insects can become infected with that cause odd or aggressive behavior like this.
I only have one dragon right now so every year I create a new bin and transfer about 60% of the roaches to the new bin. The weak, sick or slow roaches that don't climb up for food don't get transferred and get culled (exterminated) when I retire the old bin. I also do this to prevent pests from taking root such as fruitflies and gnats.
Please keep us updates as to what happens.
Perhaps you should try starting a small side colony by ordering a handful of adult pairs.
That is horrific. It's like a horror movie about dubia. Today I found two dead females in my bin, but I don't think they were eaten, I wouldv'e flipped :shock: , I just got mine recently and I'm still getting used to them, so something like that would totaaaaalllly freak me out. Just a thought, say these dubia were sick, which is why they are acting like this, would it be okay to feed them the the dragon still? I'm thinking yes because the disease wouldn't be able to spread to different animals :? , but I'm just curious.
