I am a Bti applicator in training for the Town of Lake Pleasant.  I am obsessed with outdoor Adirondack adventures, and relish the opportunity to hike in the back country.  I own a pair of old school, 16 year old neoprene boots that leak on occasion but still get the job done.  I treat streams to decrease the surplus blackfly population, benefiting our local residents and visitors who jolt our economy.  The blackflies love me, and leave craters in my skin that crust over in blood.  My guilt for killing them is only a little.  Bti stands for Bacillus thuringiensis israelensis, and is a naturally occurring soil bacterium that is utilized as a species specific death elixir for blackfly larvae.  Adult blackflies lay eggs in streams that hatch into larvae. Larvae are filter feeders and are found attached to rocks and vegetation.  Larvae undergo pupation, and the life cycle continues to the winged, terrestrial adult stage.  This is the stage that feeds on humans and is a nuisance.  The Town of Lake Pleasant’s Bti program is precise, and great care is taken during Bti application.  Calculations are made to determine how much product is applied to a stream per specific distance.  The blackfly larvae filter in the Bti and die.  Bti is non-toxic to humans and does not harm other stream critters when applied in the correct dose.      Bti is a proven method to decrease nuisance blackfly populations, and benefits the Town of Lake Pleasant’s community.  Caitlin Stewart
