Why is Critical?

The Brown Marmorated Stink Bug (BMSB) poses significant challenges both in agriculture and residential settings across many regions of the United States.

Agricultural Damage

BMSBs have become a severe threat to agriculture, impacting a wide variety of fruits, vegetables, and crops. These pests feed on the produce, leading to cosmetic damages that significantly reduce the market value, and in severe cases, complete crop failures. For a list of high, moderate, and low risk crops, see the StopBMSB . This has resulted in substantial economic losses for farmers and has affected the overall agricultural productivity in heavily infested areas.

Home Invasion

During the fall, BMSBs seek shelter indoors to overwinter, which leads them into residential homes. Their presence becomes a considerable nuisance for homeowners due to their large numbers and the unpleasant odor they release when disturbed or crushed. Managing these invasions requires effort and can be distressing for residents, impacting their quality of life during the colder months.
