watertiger21 Posted December 22, 2014 Share Posted December 22, 2014 I have a handful of G. portentosa adults. In the past few weeks I've noticed a weird white "dust" on one of my males. Not a single other roach has this... just the one male. I've gently given him baths and have entirely cleaned and sterilized their enclosure several times, but the "dust" comes back within a few days. Whatever this dust is, it's TINY. There was one occasion where I thought I could vaguely make out a little white mite walking around, but this dust stuff is sooooo tiny I'm not sure that's actually what I saw. Additionally, I observed my affected male doing some weird behavior the other day: breathing heavily, holding is butt straight up in the air, and flexing his body... I found it very strange and it's hard to describe exactly what he was doing. My impression is whatever this white dust is was bothering him (he had quite a bit on him and I had to bathe him again). Any suggestions on what this is? Grain mites? Fungus? Overgrowth of symbiotic mites? What's the likelihood of this infecting my other roaches of the same colony or moving into my other roach colonies? Thanks! Quote Link to comment Share on other sites More sharing options...
Hisserdude Posted December 23, 2014 Share Posted December 23, 2014 It sounds like some sort of mite outbreak. They could block up his breathing holes, and his weird behavior is an symptom of suffocation. I can not be sure without pics though. Try keeping the cage dry for a bit, it might kill whatever is on him. Quote Link to comment Share on other sites More sharing options...
RomanBuck Posted December 23, 2014 Share Posted December 23, 2014 Probably mites from the sounds of it Quote Link to comment Share on other sites More sharing options...
wodesorel Posted December 23, 2014 Share Posted December 23, 2014 Does he have the good mites on him? If I let the humidity slide too far down (thank you winter) then my adults start getting dusty looking because the mites go and hide in the leg joints rather than wander around on the roaches backs. Boosting the humidity fixes them right up again. Each of my adults when "nice" looking has dozens of mites wandering around cleaning them, and they are really easy to spot.

Hisserdude Posted December 23, 2014 Share Posted December 23, 2014 The symbiotic mites are reddish brown, not white. And they usually hang out under the roaches, don't they? Quote Link to comment Share on other sites More sharing options...
wodesorel Posted December 23, 2014 Share Posted December 23, 2014 Freshly molted symbiotic mites will be white. On any given hisser in my tank the mites will range in color from almost clear to black-brown. The majority will be clustered in the underside joints (which looks really freaky), but there are always several moving around on top. The big adults will have a dozen or more visible since there's so much surface area. Quote Link to comment Share on other sites More sharing options...
Hisserdude Posted December 23, 2014 Share Posted December 23, 2014 Oh, ok. My hissers only had a few, and I got rid of them before any other color mites were produced. Quote Link to comment Share on other sites More sharing options...
Sticky Posted December 24, 2014 Share Posted December 24, 2014 Isopods are great friends to have in your tanks. They do need some moist places to hide in but they eat the white mites right up. I had a huge mite problem in my centipede tanks. I bought some rolypolys and now the mites are gone! Spring tails take care of mold but I dont think they eat mites. Can anyone tell me if they do or not? Quote Link to comment Share on other sites More sharing options...

Can anyone tell me if they do or not? Isopods are great BUT be careful, I've had isopods multiply so quickly in some roach tanks that they've taken over outcompeted the roach nymphs. In my experience porcellionides are the worst about this, and I'm sure porcellio sp. would be problematic as well. I'd suggest smaller species like trichorhinas or slower reproducing ones like armadillidium. Quote Link to comment Share on other sites More sharing options...
watertiger21 Posted December 28, 2014 Author Share Posted December 28, 2014 Thanks everyone! This has been a great help. I've removed the substrate and am now keeping my hissers dry. Later on I may try to go back to a natural setup, but I'll introduce isopods to maintain any mite problems. The mites appear to be in my Gyna lurida colony too. I've always kept them humid because I thought this species needed it. Do they? Or can I convert them to a dry setup as well? Quote Link to comment Share on other sites More sharing options...
RomanBuck Posted December 29, 2014 Share Posted December 29, 2014 Nooooo. Gyna species are totally tropical. I would go get new substrate and clean the tub with vinegar. Quote Link to comment Share on other sites More sharing options...

Do they? Or can I convert them to a dry setup as well? You can keep them in the bone dry environment as long as you provide moist foods such as vegetables and fruits. A lab I know has been breeding G. luridas for several years in a bone dry environment and they still have a fairly large and stable colony. Considering the fact that their range includes desert areas, I'm not surprised at the fact that these guys can tolerate dryness. Quote Link to comment Share on other sites More sharing options...
Zephyr Posted December 30, 2014 Share Posted December 30, 2014 I have seen this "dust" on hissers that have not moved or who have not been active for many days. I think it might actually be some sort of waxy cuticular excretion that helps to keep them from drying out as it can be wiped off easily by rubbing one's finger against it, much like the powdery wax on wild black raspberry vines. It's probably harmless to all parties involved. Quote Link to comment Share on other sites More sharing options...
