Brown marmorated stink bugs (BMSB) (Halyomorpha halys) were found in Midtown Sacramento in September 2013 as a large existing population. It was the first reproducing population in California outside of Los Angeles County, but now they are found in urban areas of eight other counties. In Sacramento County, reproducing populations can now also be found in many areas see BMSB Finds link on left or here). Although no damage has been reported on any farm in California, four individual BMSB have been found in Freeport and five were found near a vineyard near Clarksburg.

This insect, about 1/2 inch (males) to 5/8 inch (females) in length, is a strong flyer and excellent hitchhiker so it will only be a matter of time before it spreads farther.
