What Does a Stink Bug Look Like?
While several types of stink bugs live in the Mid-Atlantic, rough, brown, and brown marmorated stink bugs are common. During cooler months, these plant pests often take shelter indoors. Their mottled, brown bodies offer camouflage in the garden but make them easy to spot crawling on walls or buzzing around lights inside.

Many pests similar to stink bugs wander into homes for a variety of reasons. For example, assassin bugs look like stink bugs but feed on blood. Specific trees near your building may attract other lookalikes, such as western conifer seed bugs and boxelder bugs. The stink bug pictures below can help you identify a pest issue for more effective control.

Brown marmorated stink bugs, the most common stink bug species in the area, are agricultural pests. Their blotchy, light and dark brown coloring and broad, shield-like shape let them blend in with tree bark and leaves.

Stink bugs get their name from special glands on their backs and between the first and second pairs of legs on their pale undersides. When stink bugs are threatened or crushed, they release a unique, foul odor that distinguishes them from other pest species.

A few markings can aid in stink bug identification. These insects have light and dark stripes on the edges of their lower abdomens and light bands on their antennae. Assassin bugs and western conifer seed bugs feature similar markings on their bellies, but neither of these pests has banded antennae.

The noisy, erratic flight of a stink bug makes them hard to ignore in homes or businesses. This pest has thick outer wings that cover a second set of wings just visible at the end of its abdomen. Stink bugs make a loud buzzing sound as they fly and frequently bump into people and objects.

Adult stink bugs have small, oval heads and dark, round eyes. This feature helps to separate them from other pests. Assassin bugs and western conifer seed bugs have elongated heads, while boxelder bugs have bright red eyes.

This image of a stink bug at the edge of a snowy yard illustrates their habit of moving indoors to avoid cold weather. As temperatures start to drop, stink bugs often enter buildings to find a warm place to overwinter. If you spot slow-moving, brown insects inside during fall through spring, they might be stink bugs.
Stink bug size in comparison to a penny
Brown marmorated stink bugs are about the size of a dime at a little over a half-inch long. Measuring three-quarters of an inch or more, assassin bugs and western conifer seed bugs are typically larger. Boxelder bugs are roughly the same size as stink bugs, but their black and orange coloration sets them apart.

Stink bugs have six thin legs that distinguish them from similar plant pests like leaf-footed bugs and western conifer seed bugs. The lower hind legs of those insects have a wide, leaf-like shape, while a stink bug’s back legs are smooth and narrow.

Stink bugs hatching from eggs
Stink bugs attach their eggs in groups of 20 to 30 to the stems or undersides of leaves. Local apple, crabapple, and pear trees are typical spots to find stink bug eggs, as the pests don’t reproduce in homes. Their eggs are barrel-shaped and pale yellow, white, or green. Brown stink bug nymphs with red eyes emerge after four to five days.
