Can you give a better description of the animal? What colour is it? How
long/wide? Does it have legs or claws? How many body segments (3 - 10 - or
many)?

If you mean the fat whitish grubs from one to three inches long that curl
into a ring and have six orange claws, then those are beetle larvae and
they certainly are laid in the soil as an egg. They bite too (check out
the mouthparts)!

Yes, that's the one, curls up into a ball, whitish gray and fat, obviously,
as its been very well fed :-)

How can I prevent this happening again, if at all.

Thanks, Kate
