How do I get rid of stink bugs?
What Orkin Does
Orkin Pros are trained to help manage stink bugs and other pests. Since every yard or home is different, the Orkin Pro will design a unique stinkbug treatment program for your situation.
For homes and businesses, stink bug treatments generally focus on two species that are very bothersome: the brown marmorated stink bug (BMSB) and the kudzu bug. Both of these insects create troubles for home and business owners when the pests fly to structures looking for overwintering sites. Therefore, pest management professionals focus on treatment methods that will control the bugs or help prevent them from getting inside.
In most situations, the best treatment for stink bugs is preventing them from getting inside to their overwintering sites. Your Orkin Pro will probably recommend sealing all cracks that are more than 1/8 inch wide, screening or repairing existing screens over roof vents, gable vents, windows and doors and installing door sweeps.
Chemical products can be applied around possible stink bug entry points. Based on your inspection, initial application and reapplications of products may be required to treat other stink bugs that fly to the property and attempt to get inside.

Understanding Stink Bugs
This article focuses on the brown marmorated stink bug (Halyomorpha halys).
The brown marmorated stink bug (Halyomorpha halys) is native to Asia. It has been an agricultural pest in China, Japan and Korea.
It was first collected in the United States in 1998. It is now found in many parts of the country from Maine to Mississippi and from Oregon to Florida.

The immature bug, called a nymph, is yellow and red with red eyes. As it grows, the yellow lightens to off-white. Read more about what a stink bug looks like.

Inside homes - Besides being an agricultural pest, the brown marmorated stink bug is often a pest in homes. In late summer, the adult bugs gather on homes. The bugs are seeking sheltered places to spend the winter.
In walls - They spend the winter hiding inside the walls or in the attic or crawl space. When spring comes, the stink bugs become active. As they begin to move around, some of them emerge into the living space.
Females typically lay 20 to 30 eggs which she secures on the underside of the host plant in the summer. Eggs hatch four to five days later and the nymphs will begin to feed. They undergo a series of molts until they become adults by fall. More info on the stink bug life cycle
