As a gardener, summer can feel like it takes knightly status to grow fruits and vegetables. You strap on your metaphorical armor, raise your shield, and draw your sword to battle the stink bugs, squash vine borers, armyworms, green peach aphids, and more.

 In the thick of it, it can feel like nothing in nature is on your side. But take heart – a few fellow warriors are out there fighting alongside you. One of the fiercest is the assassin bug.

These insects are voracious predators, armed with a powerful, curved beak called a proboscis that pierces unsuspecting prey. Once it strikes, the assassin bug injects a toxin that paralyzes its victim and liquefies the muscle and tissue inside. It then sucks out the liquefied remains, killing the prey.

Better still, assassin bugs feed on many of the very pests you’ve been battling – aphids, stink bugs, and caterpillars – along with flies, beetles, and even mosquitoes.

As helpful as they are in the garden, give them their space – that strike packs a punch! A “bite” from an assassin bug is painful but doesn’t generally require medical attention. Do seek care, though, if it triggers an allergic reaction such as swelling, itching, hives, or difficulty breathing.

Of the more than 7,000 known assassin bug species worldwide, only about 150 to 200 live in North America – but many of those call Florida home. Two you’re likely to meet in your garden are the wheel bug (Arilus cristatus) and the milkweed assassin bug (Zelus longipes). Give them room but know they’re on your side.
