How To Identify Stink Bugs

Adult stink bugs grow to about ¾ of an inch and they are about as wide as they are long. They have a distinctive triangle shape on their back which is where their other common name “shield bug” comes from. Adults are a mottled grayish-brown color with some lighter banding on their straight antennae and legs. They have sucking mouth-parts that they use for feeding on plants.

Why Do I Have A Stink Bug Problem?

Stink bugs are considered to be an agricultural pest because adults feed on fruits and other crops. Apples, peaches, corn, tomatoes, and soybeans are some of their favorites. Their newly hatched nymphs feed on the leaves, stems, and fruits of trees.

When the weather cools in the fall stink bugs congregate on the sunny and warm sides of homes and other buildings. They go into homes through cracks in the foundation and exterior walls. Once inside, they overwinter inside and behind walls and underneath floors. In the spring they emerge and move back outside.

Are Stink Bugs Dangerous?
