Stinkbugs get their name from the strong cilantro-like smell they emit when threatened or killed. They are various shades of brown in color and are a little over 1/2 inch long. Stinkbugs cause great damage to gardens and fruit trees. They typically enter the homes during the fall through vents, and open windows and doors. Stinkbugs are very hard to get rid of so it is important to get professional pest control help before their numbers become overwhelming.
