Brown Marmorated Stink Bug Identification & Prevention

An insect not native to our continent, first introduced into Pennsylvania several years ago.

Description

Brown marmorated stink bugs originated in Asian countries and were later accidentally introduced into Eastern Pennsylvania. Today, they are known as agricultural pests and can do significant damage to both fruit and vegetable crops. Since their introduction into the states, they have flourished and become a considerable nuisance for home and property owners. The species goes into a state of hibernation during the winter months and will invade homes in the fall as they look for a warm place to spend the winter months.

Biology and Behavior

• As their name implies, they are brown, and the adults are 5/8th of an inch in length.
• They have a distinctive shield-shaped body.
• Stink bugs have six legs, are winged, and are capable of flight.
• Their scent glands are underneath their abdomen and thorax.
• They release an odor (described as a rotten coconut or cucumber smell) from their scent glands when they feel threatened or squished.
• They remain outdoors but will often invade homes when they become active in the spring and fall months.
