Presently, there are no viable strategies for control of the Brown Marmorated Stink Bug. The use of insecticides has very short-lived effect and there is evidence of resistance development. Even where insecticide is effective, repopulation occurs through migration from non-treated areas. In addition, on-farm insecticide use is not ideal due to disruption of integrated pest management programs.  If small numbers occur indoors, they can be removed either by hand or by using a shop-vacuum.

Do brown marmorated stink bugs sting and/or bite?

No. The brown marmorated stink bug does not have the physical capacity to sting or bite. Their only means of defense is their characteristic “stink”.

Why do brown marmorated stink bugs want to get into my home?

The brown marmorated stink bug enters homes, apartments, townhouses, condominiums, office buildings, etc. in the fall so that they can stay warm during the winter.

Are brown marmorated stink bugs breeding in my home? Are they making some kind of “nest”?

No. During the winter months the brown marmorated stink bug enters a type of hibernation called diapause. During this time they do not feed and do not reproduce. In fact, females are incapable of reproducing until early spring.

Will brown marmorated stink bugs damage my home?

No. They are a nuisance to homeowners, and tenants of apartments, townhouses, condominiums and office buildings because they are large, can occur in large numbers and fly; however, they cannot cause any significant structural or cosmetic damage to your home.

Your website says to remove any brown marmorated stink bugs in my home manually, why can’t I just use a “bug bomb” or something similar?

The use of aerosol-type foggers “bug bombs” or other insecticides may kill brown marmorated stink bugs present indoors but will not prevent more from entering a structure. These materials are also not labeled for this purpose and therefore not legally allowed. Their use may also create a hazard to people using the structure. Moreover, leaving large numbers of dead brown marmorated stink bugs in hard to reach places like attics may attract other pests such as carpet beetles and mice.

If brown marmorated stink bugs cannot harm people or homes, why are they a problem?

Aside from being a nuisance to homeowners and tenants of apartments, townhouses, condominiums and office buildings the potential exists for the brown marmorated stink bug to become a significant agricultural pest in the east. In fact, severe damage to apples and pears has already been seen in parts of Maryland, New Jersey, Pennsylvania, and West Virginia.
