2017: We larvicided twice by helicopter using the same Bti (Vectobac GS) granules that we use by hand.  This larviciding occurred east of East Leavenworth Road due to the difficulty of access to the area due to brush and continued deep water.  The helicopter landed in Fromm's field to load with the granules which we provided.  Up to 20 acres will be treated. North Wind Aviation treated the area April 10, 2017 when J R Helicopters was unavailable.  J R Helicopters treated the same area May 2, 2017. 

The area treated aerially with Bti was chiefly a snowmelt area and followed an arc about 3/4 mile long against the hillside from just south of 9249 E. Leavenworth Road at the north end to just north of the conifers north of 8701 East Leavenworth Road at the south end (all east of the main road).  At the north end it funneled into a drainage ditch crossing the road.
