You can grab Wild Dung Bettles using a Grappling Hook and bring them to a safer place to tame, even on PVE. Works Great on Skull Cave on The Center and probably on caves too.

Just feed it poop you don’t have to knock it out.

I just used bug repellent and I tamed the dung beetle easy using spoiled meat and just walked out of the cave with holding the dung beetle then flew away on my Argie back home. I called him horn and he lives in a nice home.

It is possible for your dung beetle to crawl on a lit forge, which will kill it! So keep it away from any forges if possible.

Introducing the New Dung beetle!

Compost bins hate them!

You can’t feed beetles titanosaur poop. So best is diplo or bronto poop. Go in a cave with bug repellent and a raptor (a strong one). You can go to the hunter’s cave because it is the easiest cave and megalosaurus won’t spawn there nor will centipedes spawn a lot in the there. If you are far away, bring Argentavis to carry the raptor and pick up the beetle yourself. If your lvl is too low well I guess you’re gonna need to travel all the way back on raptor-back. Again.

After you tame a dung beetle, you can throw it in a cage on wonder. That way they don't get in the way.

Carryable by Kaprosuchus as of May 2020. (Not sure if they were before; Dododex says they are not)

Just feed it poop. It’s not that hard
