There a few thorns, but it is mostly thorn-free. Of the dozen or so branches, there are only 3-4 that have even a single thorn. I once had a fairly large Myer lemon tree (at least I think that's what it was). That tree was loaded with large, long, dangerous thorns. I liked the lemons but it seems that those lemons were just full of seeds. As for insects, I don't see a single insect on this citrus plant.
