There are humans that eat insects. I don't think there's something about eating insects we automatically find unappealing. I believe we've been taught that. Another idea is we don't like seeing the face of what we're eating. Most meat is processed to the point where we can't see where it comes from.

For fun my wife made some cookies including cricket powder. We told people and did not hide that fact from them. Most wanted to try it for the novelty of it and didn't find the idea disgusting.
