Placer County, CA (MPG) - According to the California Department of Food and Agriculture (CDFA), an invasive insect known as the Asian Citrus Psyllid has been found in Roseville. Asian Citrus Psyllid, or ACP is a serious pest of citrus because it vectors a bacteria that is 100% fatal to citrus trees.

As a result of this detection, CDFA is placing a significant portion of the City of Roseville, as well as portions of Rocklin, Lincoln, North Highlands, Citrus Heights, and unincorporated Placer County under quarantine.  This quarantine will mean that residents and businesses (primarily plant nurseries) will be prohibited from moving or selling citrus plant material including stems and leaves from within the quarantine boundaries.
