Stink Bugs in the House

Stink bugs found in New England include both the green stink bug (Acrosternum hilare)and the newer invasive species, the brown marmorated stink bug, or Halyomorpha halys. Both insects remain destructive pests to native plants, ornamental trees, and a variety of consumer crops grown in the area. Typically drawn to aggregation pheromones released by other stink bugs in the area indicating a food source or mating site, homeowners may notice a stink bug infestation quite quickly. Killing (crushing) a stink bug does not generally attract others of the species.

The most significant sign of infestation remains visibly seeing the insect. When threatened, the stink bug releases an unpleasant and pungent smell from glands located on the abdomen. As the weather cools, both species seek to overwinter in order to emerge during the next breeding season. Seeking heat, stink bugs may enter the home through cracks in the foundation, entryways, windows, and other points of egress. Though not harmful to humans or pets, a stink bug infestation may easily occur as the insect tends to group up when seeking warmth. Attracted to light as well, the stink bug may be found in various places in the home, near light fixtures, in kitchens by appliances, on windowsills, and on walls around doorways.
