Olympus Posted May 19, 2013 Share Posted May 19, 2013 A few months ago I lost most of my Dubias. I thought it was from my house heater failing and they got to cold but now its happening again. They act like they are parylized and die. I'm losing about 50 a day. I bought 5000 mediums and grew them to adults and now they are dying. My temps are at 90. Constant water crystals and chow. Plz help! Quote Link to comment Share on other sites More sharing options...
happy1892 Posted May 19, 2013 Share Posted May 19, 2013 Maybe pesticides or fungus. Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted May 19, 2013 Share Posted May 19, 2013 Have you had a mite outbreak? Quote Link to comment Share on other sites More sharing options...

happy1892 Posted May 19, 2013 Share Posted May 19, 2013 You are not feeding them things that could have pesticides? Quote Link to comment Share on other sites More sharing options...
Alex Posted May 20, 2013 Share Posted May 20, 2013 lets see some cage pics and close up roach pics. Also are they moulting and just dead midway?? I have had this problem aswell and good cage husbandry is the only thing I can think of. Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted May 20, 2013 Share Posted May 20, 2013 Maybe a large proportion of them reached maximum longevity at the same time? I had this happen with my discoids. Quote Link to comment Share on other sites More sharing options...
Olympus Posted May 20, 2013 Author Share Posted May 20, 2013 All the adults are fresh adults. I make all my own chow. I'm not sure how to post pics from my phone. I've raised Dubias for 2 years and never had this problem until last winter. All my temps have been perfect though and now its happening again Quote Link to comment Share on other sites More sharing options...
SLE18 Posted May 20, 2013 Share Posted May 20, 2013 Do you wash their fruit/veg really well. The pesticides used might build up over time. Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted May 20, 2013 Share Posted May 20, 2013 Does the enclosure have adequate ventilation? Gases are building up and they are killing the roaches??? : ) Quote Link to comment Share on other sites More sharing options...
Olympus Posted June 8, 2013 Author Share Posted June 8, 2013 I think I figured it out. I think I have Phorid flies! Is there anyway to get rid of them? Quote Link to comment Share on other sites More sharing options...
wodesorel Posted June 9, 2013 Share Posted June 9, 2013 I'm going through this myself and finally decided after a year of fighting and cleaning out the bins completely a few times and downsizing twice to just bite the bullet and cull the entire colony. (Last time I killed off about 90% and it didn't work.) I'm hoping to find "fresh" adults locally to start back up in the next few weeks. It was not easy making that decision, but knowing that any future roaches born were doomed to die ugly, feeling that I couldn't safely feed them to anything without knowing for sure what was wrong, and not knowing if it could spread to my other species I felt I had no other choice. On a freshly molted adult that was dead I found what looked to be roundworms. They did not seem like maggots, but looked like some sort of nematode. And my colony has been acting exactly the same as yours - neurological signs, death, and then very quickly being eaten (either by whatever hatched out of them or by the other roaches.) Haven't been getting many nymphs either. I had been thinking it was something mental causing them to attack and eat each other, but the presence of nematodes was the red flag and there was no more waiting. I will say this - the invert room is a pleasant smelling place for the first time in months! And so far there's no sign of the "infection" having spread. *crossing my fingers* Quote Link to comment Share on other sites More sharing options...

I've raised Dubias for 2 years and never had this problem until last winter. All my temps have been perfect though and now its happening again I agree about the pesticide thing. When I give my roaches apple slices or whatever fruit, I peel them competely making sure they don't get any skin at all. Rinse all fruit and veggies thoroughly.
