Assassin Bug
A predatory true bug 1/2 to 1-1/2 inches long with a curved beak and a narrow elongated head. It injects paralyzing saliva into prey and feeds on a wide range of pest insects.
Why you want them
Assassin bugs tackle prey that is too large or tough for smaller predators. They take beetles, squash bugs, stink bugs, caterpillars, and other substantial pests, filling an important niche in pest control that ladybugs and lacewings cannot cover. A single assassin bug will patrol a wide area each day and take multiple prey. They are slow to establish but long-lived, and once present in a garden they tend to remain.

What harms them
Broad-spectrum insecticides, overly neat gardens with little structural complexity, and loss of prey diversity.
Things to know
Assassin bugs can deliver a painful defensive bite if handled carelessly. Avoid picking them up. They pose no threat to humans when left alone.
