Introduction

Crape myrtles are beautiful summer-blooming trees that have become increasingly susceptible to pests, particularly the crape myrtle bark scale. Understanding how to manage this pest is crucial for maintaining the health of your trees and supporting local pollinators.

What You'll Learn

  1. Identification of crape myrtle bark scale and its impact on trees.
  2. Effective pesticide management strategies.
  3. Timing and methods for applying treatments.
  4. Importance of conserving natural enemies in pest control.

Step-by-Step Guide

Step 1: Identify the Pest

Recognizing crape myrtle bark scale is the first step in managing it effectively.

  1. Look for small, white, waxy scales on the bark of the tree.
  2. Check for signs of honeydew or sooty mold on leaves or branches.
Step 2: Monitor Pest Activity

Monitoring the scale population will help you determine the best time for treatment.

  1. Use double-sided sticky tape wrapped around the tree to capture crawlers.
  2. Check weekly to identify peak crawler activity, typically in early May.
Step 3: Select Appropriate Treatments

Choose treatments based on the timing and the scale's life cycle.

  1. Apply systemic insecticides like imidacloprid or dinotefuran in early spring before blooming.
  2. Consider using contact materials such as insect growth regulators or oils when crawlers are active.
Step 4: Application of Treatments

Proper application is essential for effective pest control.

  1. For systemic treatments, use soil drench or injection methods for long-lasting effects.
  2. For contact treatments, apply before foliage fully expands for better coverage.
