milo0 Posted July 7, 2013 Share Posted July 7, 2013 My Dubia colony has been doing amazing the past few months with maybe 1-2 deaths at the most per week (there's about 250 females, 60-80 males last time I counted) but something terrible has been happening. I had a 2nd bin with large nymphs and each time I had a new female mature, I would move them into the adult bin, only to find them dead a few days later. No visible signs of death either, but it was always the ones I had just put in. So I waited a bit until I put them in (until they were larger) and I had less deaths, but I threw the remaining large nymphs in just 2 days ago, and today I found 3 young females dead, as well as 3 males. My males are also dying at an alarming rate... I've had up to 2 die everyday... I'm not sure if it's age, because I got them last year from a person who owned them before so I'm not sure how old they are, but it's like all of a sudden they're just dying. The female's are confusing me the most though... I've only had a few large ones die, but about 80% of the new ones have died for unknown reasons. hey are kept in a dark plastic tub-ware with a wired screen for ventilation and egg crates. They're kept outside in the garage so it's in the upper 80's/lower 90's usually. I feed them a ground dry mix of high protein dog food, oats, and fish food, as well as oranges, veggies, fruits, and any left over greens from my bearded dragon. I make sure to take out any fresh food no later than a day, and their dry food is kept away from any moisture. I don't have a measurement of the humidity, but I don't think that's the problem since I've seen no shedding problems, and they always have a source of humidity in the bin. I clean them out whenever I need to harvest the babies, so usually it would be every 1-2 months. I replace the egg crates and usually just scoop out most of the poop and leave some in there for future baby nymphs, but I don't disinfect it or anything. There are no mites or other bugs in there besides those gnats sometimes but they're harmless. Any one know what's causing this? I didn't save nearly enough large nymphs for restocking the dying adults so I'm afraid my colony is going to crash if I don't figure out what's killing them. Please help!
