Stink bugs can go from brown to mottled grey and are roughly pebbled, but adults may look bright green. They feature long heads with antennae in front of their eyes and have wings for flying. They are usually no longer than one inch long and have an oval shape.

Only adults are good fliers. Nymphs (immature insects) come out from their eggs with red eyes. To grow, they molt and shed their skin five times before reaching their adult size. In general, adults lay about 300 eggs which hatch in about a week and come to mature size in less than five weeks.

How To Know You Are Infested

Stink bugs don’t move much. It is common for homeowners to tind these insects inside as soon as the temperatures drop after the winter. While a couple of bugs shouldn’t concern you, a large number of dead and alive stink bugs might signal a severe infestation, which you should manage promptly.

These insects can even cause damage to crops and plants as they like to feed on flowers, fruits, seeds, and leaves. If the population that attacks you is large, you may notice wilted brown leaves with discoloration.

While they can control some harmful caterpillars, you may want to eliminate them as soon as possible. You can contact a professional bug control service to assess the damage and identify the access points for taking care of this bug.

Control and Prevention

While it is not easy to control them, you can prevent stink bugs from attacking your house by ensuring you seal any cracks around windows and doors. You may want to rub them with aromatic dryer sheets to repel them.

Common entry points for these insects include doors, electrical outlets, skylights, and chimneys. Plus, these bugs like lighting. You can change your exterior lanterns to make them less attractive to stink bugs by choosing yellow bulbs or sodium vapor ones. Also, ensure you pull shades or blinds closed at night.

Since these bugs are invasive species, they don’t have natural predators that feed on them, causing them to spread quickly throughout the country. While they can damage crops and ornamental plants, they are not considered a threat. These insects do not bite or sting.
