Stop at your local farm supply store and pick up a hose end sprayer ($20), not your standard Miracle Gro sprayer, although it may work and a bottle of BT (+/-$10) and have at em'. Cant remember what the BT stands for, Bacterium something? The sprayer I picked up has a dial to regulate the product and a hoze type nozzle that will spray in a fan or a jet to reach higher. Of course if you had a pressure washer........
Update: Washed the boat Friday am, not a catapiller in sight, just looked at it this am, covered with baby Gypsy moths and their droppings!
