Phanaeus vindex?

So I visited a fellow blacksmith/knifemaker about two or three weeks ago who lives out in the boonies of Arkansas, I told him about my interest in beetles awhile back and told him to grab any unusual beetles he could find. When I got up the driveway he was standing there with his neighbor holding a plastic 5 gallon bucket I had a nervous feeling about the situation because they both looked rather cheeky. I went up to them and low and behold- the bucket contained 6 phanaeus vindex dung beetles! They said they found them on what they thought was wild boar droppings. I gladly accepted and took a bucket of pig dung from the neighbors pet potbelly pig. Back to present day Ive been keeping the beetles in a plastic tote in the guest bathroom with dirt from my backyard that I sifted thoroughly. And the females made four brood balls, two of which were covered (and pretty much filled with) small white worms I accidentally broke one of the wormy ones open and found no egg, I figured the other worm riddled brood ball would have the same result so I tossed it, my questions are- I am pretty sure the worms came from a bunch of small flies that looked a lot like fruit flies, how do I prevent them from laying eggs in my beetle bin? The bin has minimal ventilation and is kept at around 68f. How do I speed up egg laying, I have two males and four females so I figured there would be at least 8-10 brood balls by now, but that was just a guess. More heat? Change dung more frequently so its fresher? I took the last bit of dung out because it started to get moldy and got covered in those fruit flies and worms. How should I keep my current two brood balls? Do I need to keep them warm? If so how warm? Should I cover them in substrate or place them in a empty container? I read the dung beetle section in orins ultimate guide, but Im going to go over it a few more times and see if there is any tips I missed. Thanks.

 
Youre already doing better than me. 2 weeks and I have zero brood balls to show for it with 2 males, 5 females. How long did it take for yours to make the 4 brood balls? Same thing here; I ended up removing dung as it was starting to get moldy.

All of my knowledge is from the ultimate guide, so Id trust any experienced advice over mine.

Temps should be between 72F and 85F, with good ventilation in the container. Clear lid to allow in daylight, or light from s heat lamp. Dung should be a baseball-sized amount per pair once per week.

Brood balls need to be placed egg-nub up in moist sub, fully buried. It doesnt say anything about temps for brood balls, but I would imagine they need to be in that same 72f to 85f range.

Like I said, I had yet to find a single brood ball, or even what seemed like them starting to be made, but mine absolutely tore apart and buried all of the dung in short order. Only thing I have to show for it is a handful of fly pupae that Im pretty sure hitch hiked in with the horse dung.

I read over the dung beetle chapter again last night and came to the conclusion that what I found were half constructed brood balls. So I’m guessing I should change the dung more frequently, keep them warmer, and give them several weeks (I believe the guide stated 7 weeks?! Though I could be wrong.) I bet you anything your beetles are making brood balls right now and just need more time (and fresh dung.) Good luck and thanks for the help!

 
7 days

(the complete guide to rearing the rainbow scarab - pg 22).

Other than that, your setup sounds very close to mine. If you continually have trouble with fly maggots you may need to freeze the dung ahead of time.

Best of luck!
