How often will I need to treat my trees?

If you decide to treat your trees, starting in May after the trees have budded, you may need to treat every 7 days or so, depending on the insecticide you choose. Douglas Fir Tussock Moth (DFTM) may emerge from their eggs over an few weeks so treatments may need to be spread out. Most of the insecticides registered for use on DFTM are short lived and break down quickly. Please refer to the product's label for specific directions.
