Birches, maples, oaks and other tall trees are susceptible to aphid infestation during the growing season. The dripping you are seeing is a sticky substance that the aphids excrete while sucking on the leaves. This substance is not only annoying but can be damaging to patios, decks and automobiles.
We can help you prevent this problem by treating your trees now. One injection of a systemic insecticide in February will give you year-round aphid control. Call us for a free quote.
