u/Only_Bug_9743

Found two of these guys while doing maintenance (their home had to be cut down) and I would like to care for them myself, but I noticed suspicious spots. A bug ID website told me they were parasitoid fly eggs and will eventually kill the cats but can be pierced via needle to save them. Is this good advice? Is it too late?
Found in MN and I’m too stunned to speak. They’re like irl Pokemon.
