Good call dad. Yes, they are the BMSB. A true pest... They are everywhere along the Wesel Blvd and Greenberry Hills area. My office is out that way, and they annoy me beyond belief. lol They are harmless to humans... just annoying.

I emailed the Dept of the Env about the bugs around my friends house in G'Berry Hills. I am concerned about them damaging the fruit crops in Smithsburg. For that to happen, all they have to do is hitch a ride on a few cars out to that area, and create a breeding colony. Scientists are worried about them making there way south, where they don't have to go inside for the winter. This bug could devastate certain tree-fruit crops.

Here is an extract from an email that i had with the Department of The Environment.
Thank you for contacting us about this. We are aware of the Hagerstown nuisance population, but not of a shift to peaches or other economic crops in the area. This is of great concern to us and if it is occurring, we would certainly like to know. We are also doing some trapping and outreach statewide to see their range is expanding. If you would like, we can have someone stop by to assess your situation when they are checking traps in the area - I am also copying this email to some MD Cooperative Extension folks who might be interested in this issue.
Regarding keeping them out of buildings, exclusion is the best approach - caulk around windows and doors, place a fine screen mesh on the inside surface of attic vents, and seal gaps around window or wall air conditioners. You need to do this before they move inside for the winter. There are currently no recommended chemical controls for BMSB.
