Stink Bugs Can Invade Homes Through Cracks As Small As 3 Millimeters
The brown marmorated stink bug is an invasive insect species that has only been a known inhabitant of the United States since 1998, but the insect pests were probably accidentally introduced into the country sometime before this year. This species was first discovered in Allentown, but it has since spread to most eastern states, and several western states.
The brown marmorated stink bug is recognized as an agricultural pest in its native Asian range, and this is the case in the US as well, but invasive stink bugs have become particularly significant nuisance pests inside and outside of homes in residential areas during the fall season. The brown marmorated stink bug tends to gravitate toward homes during warm days in the fall in an effort to secure warm shelter for the winter. These pests can reappear on sunny days during the winter before emerging in large numbers come spring.
Brown marmorated stink bugs are often found clustered together in large groups on the external walls of a home and on patios, and they have been known to invade homes in the thousands. Some stink bugs establish nesting areas behind furniture, while others can be found crawling about in the open. Killing brown marmorated stink bugs when they are encountered indoors is almost always insufficient to end infestations, and squishing them causes their foul-smelling internal fluids to leak into homes.
The brown marmorated stink bug is hard to miss, as these pests grow to an inch in length and they possess a tan to dark brown exterior shell. Despite their relatively large size for insects, brown marmorated stink bugs are known for entering houses through tiny cracks and gaps in the exterior walls and the foundation of homes.
A recent study has revealed that a typical brown marmorated stink bug specimen can enter cracks as small as 3 mm, or .118 of an inch wide, which is only the size of two stacked dimes. The study also found that these bugs can enter holes as small as 7 mm, or .28 of an inch in length, which is as long as a grain of rice. The study’s authors claimed that smaller sized adult stink bug specimens may be able to fit through cracks and holes that are even smaller than the above mentioned figures.
