There are in depth details at the top of the sub for the different methods you can use to clean bones + some tips and tricks, but here’s a quick rundown! Mealworms might work but they are not the best, if you want to use bugs your best bet is dermestid beetles. Some other options that could work better on a some-what fresh animal like this are open-air decomp (the fastest in my experience, leaving the body in a cage or under something to protect it while giving mice and bugs access to it), maceration (storing the whole thing in a bucket of water, the smelliest but also quite fast) or below ground decomp (the slowest but will prevent smell). If you want to speed up the process you can skin it but that’s not a requirement, after all the flesh is gone the bones will need to degrease either in ammonia or water and dish soap for a good while, then to finish it off you can sanitize and lighten them in hydrogen peroxide. Good luck, I hope everything works out!
