Are these something other then fruit fly? They been attacking my dubia also.
Never seen anything like this .
Took container outside as a precaution.
Spider was alive less then a week ago my last feeding.
Sorry if this sounds like a dumb question I just need it fixed soon.

Do the run or do they fly away when you go after them? That's a pretty bad infestation to not notice before the T died.

They may be phorid flies. If so, then they are more likely to run around rather than fly (though they are certainly capable of flying). Phorid flies will seek out and lay their eggs in decaying organic material - including dead feeders, decaying food in your dubia tank, and dead spiders or other invert pets. They can detect dead or dying animals almost immediately and will respond by swarming the affected tank and laying eggs on any suitable organic material they can find. They have a very short life cycle, with larvae hatching out and begining to feed within 24 hours of eggs being laid. They do not usually hurt live animals, but I can't altogether rule it out, either. I've heard that the larvae can feed on sick or injured animals, so a serious infestation might be able to kill a weak or injured animal. The adult flies are able to detect a dead or dying animal almost immediately and will cover

I see them flying but they been attacking my dubia colony, T mighta been dead 5 days right after last feeding watering.
Do fruit fly maggots feed on dubia waste also??

Actually attacking or just in there? Attacking is phorid flies, in there possibly not.



Fruit flies feed on moisture. Dead things, food left over, water crystals. Deprive them of that and they die off quickly.
I’ve dried everything out cleaning dead dubia out of every cage , these freaky things won’t die off.
It’s a shock this was a such a healthy T just die outa non were poor spider.
I don’t have a camera to set up too observe I’ve not seen a fly attacking. But I can’t afford to buy a camera to observe them now. Just take pics of aftermath Thisbe first non MM deaTh since king baboon months ago.
What ever they are I’ve killed 1000s in diy traps and sticky traps no bottom Elon sight . Catch swarms of them leaving my dubia containers.
Dried out cages too

"Attacking" is a bit of a misnomer. Phorid flies are not predatory and don't "attack" things in an aggressive manner. What you would see is the flies just walking around on stuff or landing on it - and if you looked really closely, under magnification, you would see them laying eggs. The eggs can be seen with the naked eye, but they are really teeny - just little white specks.

It is possible that the fly infestation might have killed your spider - but is equally likely that the spider died of other causes and the opportunistic phorid flies laid eggs on the dead (or dying) spider.

They are also really hard to get rid of in a dubia container because there is so much potential food for them. They'll eat the same food as the dubias, plus dead roaches, molts, roach waste, or any liquids that are left behind by the food, by dead bugs, etc. that soaks into the substrate or bedding or egg crate or whatever you're using.

How do you not check on your baby for an entire week? I can hardly go 12 hours...!

Sounds painstaking but a thorough cleaning of the dubia container might be in order

It had been sitting in same spot, I looked at it within the week. Just didn’t notice all these flys til yesterday on the container. Gotta clean dubia tanks.

Good luck. i am in the process of trying to purge those (or similar) flies from my dubia colony. They ( So far keeping things completely dry is the only thing that has worked in a few of my smaller bins. Unfortunately my large breeding colony is being killed off fast enough that the constant deaths have sustained the flies. So far no issues with any spiders, but i keep 'almost' exclusively dry or drought drought tollerant which is probably what kept them from being bothered.

IME covering ventilation with pantyhose keeps them out sufficiently well, but once they’re in they’re a massive pain to get rid of outside starting fresh. I also add dead feeder carcasses to sticky traps, as this increases the catch count significantly.

Is T enclosure damp? Also, I couldn't tell if that's a pale yellow/beige rock or a mushroom.
Anyway, very sorry you lost your T. :(

I also recommend a thorough cleaning of feeder enclosure -- really, a complete do-over. I also recommend keep using fly paper/tape and to continue to dry everything else out if possible. Also, remove any feeder food if not consumed within in 24 hours (remove fruit (or anything looking on verge of decaying) not consumed within 12 hours.). But really, any food fermenting or a rotting food source, coupled with additional moisture is just going to encourage these flies.

The enclosure was dry it even still had some water left, maybe an underlying condition weakened the T and fly’s moves in either before or after it dies.
I’ve been painstaking remove all dead or uneaten prey.
Looks to be a white smooth rock, I’ve never seen anything like this . I see flys flying and running hope it’s not two species.

Was much less then a week , I think they might be phlorid flys see then running more then flying.
More like a pack of these fly’s hanging out around dubia tank . No idea how to kill them off, severe knee pains trying to get checked out didn’t help . I still feed and water them just less at a time, once a week or whenever they run out of water.
What’s a good water dish so dubia won’t drown? None died in this tank but I see drowned dubia.
Roaches just aren’t very smart, but hide welll.

I use water crystals for the roaches as they are cheap and the roaches cannot drown in them.

I would take the water out of the vin completely and just offer for a couple hours every few days until the flies are sorted out. Also, if the flies aren't in the dubias yet, i would try to quarantine the dubia colony away from them somewhere to keep it that way. Not sure what your colony is like, but i've been building mine up for about a year to try to supply the LPS and lost probably $1500+ dollars worth of roaches just after i was producing enough to start selling... Very frustrating situation.

While I haven't tried pantyhose, I have noticed that the dang things seem to be able to lay eggs right through the fabric mesh tops of the fruit fly cultures. We have to keep our fruit fly cultures in a different room than the rest of the bugs, just to keep the phorid flies from getting in to them. They appear to be able to out-compete the fruit fly cultures for food, or maybe the phorid larvae eat the fruit fly larvae or eggs, because once they invade a fruit fly culture, it ends up being mostly phorid flies instead.

Been years since a outbreak of these , gotta keep cleaning cages. DIY fly traps don’t kill enough, I’ve seen hundreds or thousands killed already no end in sight. See less but not enough less, dubia beeen decimated. Gotta keep throwing out egg cartoons so many eggs laid on them, and pupae.

All around one bolas!!!

Once you have phorid flies, they’re extraordinarily difficult to eradicate 100%. They can be controlled by removing organic material and keeping moisture levels down. The larvae must have moisture to survive, but all they need is within the body of a freshly dead roach. Boluses that don’t dry out are also prime material. Cultures of large bodied roach species are particularly prone to infestation, in which case a cleanup crew of dermestids or lesser mealworms will be required.

I keep springtails in my enclosures (except the drier ones). Never have flies or mites, and they help a lot with mold. Occasionally when it's really humid mold can overwhelm the springtails ability to eat it. I've had lots of T's molt with springtails in the enclosure -NO PROBLEMS.

Store bought mealworms,?
