They would almost certainly escape into the wild and breed with native or natural species, creating problems like how asian beetles are replacing ladybugs, and earwigs spread like an invasive species, not to mention African honeybees displacing other species of bees.

Why don't you answer the question?
Why are you asking it? It's obvious that I already know that bugs are farmed, and that they have escaped in the past, because in the original post I mention honeybees, which aren't even native to North America, but which were brought over by Europeans.
Go be troll somewhere else.
Then why do you pretend they aren't? Did you read your own post title?
Nobody is pretending anything, except you I suppose. As I said before, it's a question of scale.
