Birch Leaf Miner

How to spot: Damage will be recognized on affected leaves appearing as white and black spots. Leaves will eventually turn brown and become brittle. If left untreated, trees can lose large amounts of leaves and become susceptible to other insect infestations. Our Recommendation: Pesticide application every 24 months as trees are budding. Providing the tree with adequate amounts of water, nutrients and fertilizer will also assist in combating an infection.
