    ATTACK of Lecanium Scales! - Gross Lawn Care Stuff

    Licanium ScalesQue the scary music and dramatic pauses, because this article is going to get gross! We all know that insects are starting to become active in your lawns and on your trees and shrubs. But today we'll look at perhaps the grossest one out there that (wait for it...) could be in YOUR LANDSCAPING RIGHT NOW!  AHHHH!!!!!

    Yuck! What Are These Things?

    Lecanium scales are tiny little insects that feed on the sap of a certain variety of trees, including maples, oaks, pines, and other trees. As they consume your tree's sap, they expel a liquid waste often referred to as "honeydew." This "honeydew" is often the first sign of a possible infestation, making the leaves of the plant shiny, and damp looking.

    After spending the winter clinging to twigs and branches in a "dwarf" or immature state, Lecanium scales develop a waxy covering that resembles a small turtles shell. This shell is developed to protect a large number of eggs that they have laid. After hatching, the larvae moves to the leaves of the plant, consuming the tissue.

    What Can I Do If They Attack My Trees!

    Lecanium scales should be treated with a dormant oil in the early spring before they have a chance to become active. Timing is the critical aspect of treatment, because once they reach a mature state (with a shell), it is difficult to control this insect. Here are your options:

    1. Tree & Shrub Program: Lecanium scales often attack stressed or diseased trees. Developing a strong fertilization and dormant oil program for your landscaping will eliminate the chances your plants will get these scales.
    2. Remove Infected Branches: By trimming out the branches that are infected, you reduce the chances of them spreading to the entire tree or plant.
    3. Insecticide Drench: When reaching this part of the season, dormant oils will have little effect on the scale, this according to the University of Kentucky College of Agriculture. Their recommendation for when scale reaches this stage is a product known as Imidacloprid. This product can be used in a soil drench, allowing the tree to take in the liquid, killing the scale through the sap that they feed on.
