Evaluation of Exclusion to Prevent Indoor Infestations of the Brown Marmorated Stink Bug
Date:2015 to 2016
Brown Marmorated Stink Bugs (BMSB) are invasive insects that damage plants outdoors and overwinter inside structures. Pest management professionals receive calls about this and other overwintering pests in the spring and fall, when pests attempt to exit and enter structures, respectively. The goal of this project was to evaluate the effectiveness of physical exclusion in preventing brown marmorated stink bugs from entering buildings. Resident responses to a survey indicated an overall decrease in problems with stink bugs, and a total of only eight overwintering pests were captured on traps inside homes: two from units that received exclusion, six from units that were not sealed against these pests.
The Brown Marmorated Stink Bug is an invasive insect from Asia that was accidentally introduced to the United States near Allentown, PA. Since its original discovery in the 1990s, this pest has dramatically expanded its range and population size, and can now be found in 41 US states and Canada. This insect is an agronomic pest because it damages crops such as apples and soybeans among others. It is also a structural nuisance because it enters buildings in the fall. While the insects do not harm the structure, they cause distress in homeowners, resulting in pesticide applications. In addition, dead insects that do survive the winter may provide allergens that result in an allergic reaction, and can serve as an attractant/food source for secondary pests and mice.
The goal of this project is to determine if sealing gaps around windows and doors can reduce the number of stink bugs that enter buildings.
A lack of results from this project precludes an assessment of impacts. Specifically, very few insects were captured using two types of traps within both treatment and control units. Thus, it is not possible to say whether exclusion was effective at reducing indoor populations of brown marmorated stink bugs.
