An assassin bug bite delivers a sharp, burning pain that catches most people off guard. These predatory insects rarely target humans on purpose, but a defensive strike from their needle-like mouthpart injects venom that can cause swelling, numbness, and reactions lasting days or even weeks. This article breaks down what the bite looks and feels like, how to treat it, and when a trip to the doctor is warranted.

If you’re wondering what is an assassin bug, here’s the short version: they’re predatory insects in the family Reduviidae that hunt other bugs for a living. They use a three-segmented, straw-like mouthpart called a rostrum to stab prey, inject digestive venom, and slurp up the liquefied insides.
Humans are never on the menu. Most bites happen when someone accidentally grabs, sits on, or brushes against one of the nearly 200 North American types of assassin bug. The bug interprets the contact as a threat and drives its rostrum into your skin in a purely defensive strike.
