The California Department of Food and Agriculture (CDFA) and the Ventura County Agricultural Commissioner's Office announced the eradication of the European gypsy moth infestation in the Ojai area last week.

The infestation was originally detected in 2007 when four moths were found in an insect trap. Additional moths, egg masses and larval cast skins were found in the area in 2008. The infestation was eradicated using applications of Bacillus thuringiensis kurstaki (Btk), an organic treatment that uses a naturally occurring soil bacterium against the pest.
