Is assassin bug poisonous?
I assume that you mean poisonous for humans. There are many species of assassin bugs (about 7000), so there is not simple to this question. But with many species, you will definitely notice some (or a lot) swelling and pain when you get bitten. It’s not something that’s life threatening, though, unless you are allergic to insect bites. In that case an assassin bug bite may be just as dangerous as a bee sting.
