many places that sell crickets may have silkworms as well. Just have to check the various online feeder suppliers. I have quite a few to choose from here in Canada...(though I think one has gone out of business...but they weren't all that good to start off with).

Mulberry farms is probably the biggest one in the US but pretty sure there are more than just two. May have to search a few businesses to find which ones supply silkworms closest to you.
