Stink bugs earn their common name from the offensive odor they emit when bothered. Several thousand species of these pests exist worldwide, and all share this defense mechanism against predators. Often mistaken for squash bugs, stink bugs aren't as particular about the plants they damage. They feed on beans, peppers, tomatoes and many other garden favorites, as well as squash. Some also spread plant diseases. The brown marmorated stink bug, an invasive Asian insect, causes added turmoil in fall, when they try to enter homes to overwinter.

Identification: With so many species, stink bugs vary significantly in appearance. The shield-shaped adults typically grow up to 5/8 inch long and nearly as wide. The most common types range in color from mottled brown and cream to green, but some species carry brightly colored markings. Smaller, rounder nymphs vary from yellow and orange to black, brown, red and green. Clustered eggs also vary in color and shape, but they often look like tiny barrels.

Signs/Damage: Stink bugs damage plants by piercing and sucking plant sap from leaves, buds, blossoms and fruit. Damage kills seedlings, stunts plant growth, wilts leaves and creates superficial spots and pits. Fruit may drop, become deformed or fail to form at all.
