New Dubia Colony Not Producing

    Hello all,

    Roughly a month ago I decided to increase my dubia roach production so I added a second tub and started it off with roughly 40 adult females and 20 males. Later I added 100 large nymphs.

    The second tub is running on the same thermostat as my original but it has a bit more flexwatt mat so it tends to run hotter(90-95) while my original tub is more like 75.

    I checked the new tub today and there where almost no(maybe a dozen) small or baby nymphs. The adults looked fine and there were only one or two dead adults. I can see small nymphs in my original tub so I know it is still producing.

    One idea I had is that somehow I let my water crystals get too liquidy and the nymphs are drowning. I saw some small black dots in the crystals when I checked today. They were too big to be poop so maybe young nymphs. The strange thing is that I have used the same crystals in both tubs.

    Any ideas?

    Keep them hot and well fed and give it time. I don't know how big your original tub is but you might be better off moving them all in together. They seem to produce better when they are a bit cramped. Make sure that you are offering some fresh fruits to really get them going. Whenever I add oranges or any kind of fresh fruit the whole colony comes alive and gets loud.

    I think the temps are too high. Try for 85 to 90, and about 50% humidity. Been through this and made a lot of mistakes in the beginning. The excess heat may be killing off your nymphs, and it will take more than a month to really get going anyway.

    A month?? give it 90 day b/c a female can only produce twice a month. they need to get accumulated first.

    Thanks for the info guys. I did not expect the colony to take off in a month but I did expect dozens of little tiny guys given the number of mature females I started with I literally saw ten or less. Everything I have read said the higher temps would increase breeding but given the side by side results I am beginning to question that. I have heard that density aids breeding but I would think that a population of roughly 150 or so in a tub would get something going.

    I am going to drop the temp and see what happens.

    Thanks again for sharing your knowledge.

    Try giving them some halved oranges. That seems to fire them up.
