At the Sanctuary, we had something similar happen with another species. The Nubbins, as someone else dubbed them, were a bit more dangerous than these seem to be, capable of thinking as a hivemind, sacrificing individuals for the good of the many, and could eat through anything or anyone. [ yeah. think about that for a minute. ]
We ended up mimicking their distress call so we could corral them in an area with a lower temperature, thus subduing them and slowing both their metabolism and reproductive cycles. I've no idea what the natural habitat for these creatures is, but we might be able to try something similar.
