Characteristics and Appearance

Stink bugs and kissing bugs may seem similar at first glance, but their physical characteristics set them apart.

Stink bugs are shield-shaped insects, typically about ½ to ¾ inch long, with a broad, flat back. They come in various colors, but most are brown or green. Their bodies have distinctive triangular plates on their backs, and their antennae have alternating light and dark bands.

Feeding Habits

Understanding the feeding habits of stink bugs and kissing bugs is essential, especially considering the health risks associated with kissing bugs.

Stink bugs are primarily herbivorous, feeding on plant juices. They use their needle-like mouthparts to pierce and suck the sap from fruits, vegetables, and ornamental plants. While stink bugs can cause significant damage to crops, they are not harmful to humans.

Kissing bugs, however, are blood-feeders, which makes them a concern for human health. These bugs are nocturnal and tend to feed on the blood of mammals, including humans. Kising bugs get their from the habit of biting people around the face and eyes. Unfortunately, kissing bugs can transmit Chagas disease.

Living Habits and Habitat

The living habits of stink bugs and kissing bugs also differ, influencing where you might encounter them.

Stink bugs are typically outdoor pests, often found in gardens, orchards, and agricultural fields. However, as the weather cools, they seek shelter indoors, invading homes to overwinter. They are often found in attics, walls, and other quiet, undisturbed areas.

Kissing bugs, in contrast, are often found in rural and suburban areas, particularly in the southern United States, Central, and South America. They hide in cracks and crevices during the day and emerge at night to feed. Kissing bugs are commonly found in woodpiles, under porches, in dog kennels, and occasionally inside homes.
