Dubia troubleshooting brainstorm.

I've found this to be helpful. Maybe other people will too.

My dubias are still not producing nymphs, but at least they're breeding, as an aborted oothacae I found proves.

My box has been at the correct temperature for several months (though it might have gotten too low several times). The humidity is high. I feed the roaches dubia chow, lettuce and carrots.
Here's what I think may be wrong:

1.Stress: I've moved the box around too frequently or the bugs arrived stressed.
2. Too many males. Do I just kill some of them? Seems a little wasteful, but if they're eating nymphs...
I'm going to divide my colony up and see if that helps.
3. Not enough frass. Maybe I've been cleaning out the box too well.

If anyone wants to make a suggestion, please do.

That is frustrating! I wish I could help, but I've never researched breeding dubias as I found myself quite allergic to them :/ Good luck!

I was having the same issues you are dealing with when I first got my roaches. I don't know if this is the "key" to breeding them, but I've noticed a boom in population after feeding them the occasional orange or grapefruit. Could just be coincidence, but that's what has worked for me.

Also, for what it's worth, I'm always harassing mine looking for nymphs and so far I haven't seen a change in their production.

Good luck!

Weird! Maybe they need vitamin C?

I separated the males out until I got a 1:3 ratio in the main bin.

...then my cat knocked over the bin and most of the roaches escaped. The nine or so I found were on their backs and probably traumatized for life. I spent a year raising those things!

On the bright side, maybe, the aborted oothacae I found was more developed than the first one, though the nymphs were not entirely formed yet.

You will want to feed them fresh fruit and veggies daily if you can, make sure the male to female ratio is good, and make sure they are crowded, but not over crowded. You can tell if they are over crowded if the males start really nipping each other's wings. Other than that, disturb them as little as possible and wait. It sounds like yoo may have lost quite a few; discountdubias.com is the cheapest place I've seen to buy them.

Roaches like it crowded. I think that dividing them up would be a BAD idea...
Perhaps if you have to start over, start with a larger quantity at first.
