Stink Bug

What are Stink Bugs and where did they come from?

The brown marmorated stink bug, an insect not previously seen in the United States, was apparently accidentally introduced into eastern Pennsylvania. The first stink bug was collected in September of 1998 in Allentown, Pennsylvania,  but probably arrived on the scene several years earlier. As of September 2010, the stink bug known as Halyomorpha halys has been recorded in California, Connecticut, Delaware, Florida, Indiana, Kentucky, Maine, Maryland, Massachusetts, Mississippi, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, Washington, D.C. and West Virginia.
This true bug in the insect family Pentatomidae is known as an agricultural pest in its native lands of China, Japan, Korea and Taiwan. Recently, the stink bug has become a serious pests of fruit, vegetables and farm crops in the Mid-Atlantic region and it more than likely that it will become a pest of these commodities in other areas throughout the United States. 
The stink bug becomes a nuisance pest both indoors and outdoors. It is attracted to the outside of houses on warm fall days in search of protected areas to over winter in, such as around doors, windows, under siding, soffit or any other crack and crevice they can squeeze in to. The stink bugs often reappears during warm sunny days throughout the winter, and again as it becomes very active in the spring. Often they emerge inside the house from behind doors and window frames, curtain rods, etc, where they have been over wintering.

Before Stink Bugs Make Their Entrance


Mechanical exclusion is the best way to keep stink bugs from getting into a home or building. Cracks and crevices around siding, doors, windows, utility lines and pipes, behind chimneys, and underneath fascia and other openings should be sealed with silicone, latex caulk or stuf-fit copper wool. Damaged door or window screens should be repaired or replaced.

Applying insecticides to the exterior will offer some minor relief from infestations when completely sealing the exterior is difficult or impossible. Insecticide applications should consist of a synthetic pyrethroid such as deltamethrin, cyfluthrin, cypermethrin and should be applied in the fall just prior to the stink bug invasion.


After Stink Bugs Have Entered the Living Space


If numerous stink bugs are entering the living areas of your home, attempt to find the openings where the insects may have gained access. Typically, stink bugs will emerge from cracks around baseboards, window or door trim, and around exhaust fans or lights in ceilings. Seal these openings with caulk to prevent the stink bugs from crawling out. Vacuum up live and dead stink bugs can from interior areas. However, it is best to use a old  vacuum or shop vac and to store the vacuum in a shed or garage as the vacuum cleaner may acquire the smell of stink bugs for a period of time. Discard the bag when finished vacuuming.

Vacuuming is the best way to remove stink bugs from inside the living space of the home. We recommend only treating around doors and window sills inside the home. Have that vacuuming cleaner handy from the garage or shed to suck up any stink bugs that end up in the living areas. Killing too many stink bugs inside the home can result in other pests invading that may choose to feed on the dead stink bugs. Again vacuum up or physically remove any dead stink bugs inside the home.Do not use foggers or dusts in wall voids where stink bugs may die in mass and cause other pest problems. It is impossible for you to remove the dead stink bugs from inside interior walls, short of removing the wall. However insects such as carpet bettles will have no problem getting back there and feeding on the dead stink bugs and then take up residence in the inside of your home themselves.


Stink bugs are not known to cause harm to humans, although homeowners become alarmed when the bugs enter their homes and noisily fly about.  The stink bug will not reproduce inside structures or cause damages.  If many of them are squashed or pulled into a vacuum cleaner, their smell can be quite apparent.
