This bug has become a nuisance pest both indoors and outdoors when it is attracted to the outside of homes on warm fall days in search of protected, overwintering sites.  It reappears during the winter during warmer sunny periods, and again as it emerges in the spring.

Before Bugs Enter a Home or Building:  Mechanical exclusion is the best method to keep stink bugs from entering.  Cracks around windows, doors, siding, utility pipes, behind chimneys, and underneath the wood fascia and other openings should be sealed with good quality silicone or silicone-latex caulk.  Damages screens on doors and windows should be repaired or replaced.

Exterior applicationsof insecticides may offer some relief from infestations where the task of completely sealing the exterior is impossible.  Applications should consist of a synthetic pyrethroid and should ONLY BE APPLIED BY A LICENSED PEST MANAGEMENT PROFESSIONAL in the fall just prior to bug congregation.  Unfortunately, because insecticides are broken down by sunlight, the residual effect of the material will be greatly decreased and may not kill the insects much beyond serveral days or a week.
