Signs of Japanese Beetle Damage

  • Rapid canopy thinning

 

Severe infestations can strip trees in weeks.

Our Protection Program

Treatment options may include:

  • Foliar sprays to reduce active feeding
  • Soil treatments to reduce beetle pressure
  • Basal bark applications when appropriate

 

Timing is critical to protect foliage before peak feeding.

Why Early Action Matters

While one season of feeding may not kill a healthy tree, repeated defoliation weakens it over time.

Weak trees become:

  • More vulnerable to disease
  • Less drought tolerant
  • Structurally compromised

 

Preventative control protects long-term health.
