INFESTATION
The Emerald Ash Borer a new arrival from China will in time destroy every ash tree in the USA. Once infected a tree has only one to two years to live. The Asian Long Horn Beatle is just as deadly but attacks almost all American hardwood trees.
Emerald Ash Borer
Here are side by side examples of treated and untreated trees.
The video below explains the Emerald Ash Borer in depth.
EMERALD ASH BORER
These insects have a unique appearance. Bright emerald green with golden sheen. They leave distinct “D” shaped holes. Once they tunnel into the sapwood the tree will show signs of stress and die within one or two years. Our treatment enters the vascular system of the tree. No pesticides are realeased into the environment. When the EAB begins feeding on treated tree it will die and the tree can begin healing itself.
EMERALD ASH BORER LARVAE
The larvae live under the bark of the tree and feeds off the vascular cambrium. The larvae tunnel into the tree destroying the phloem, vascular cambium and effectively girdling the tree. Nutrient carrying sap can no longer travel up the trunk and the tree dies.
EMERALD ASH BORER MAPPING
This mapping shows the risk of invasion within four classifications: Low, Moderate, Moderate High and High classes.
ASIAN LONGHORNED BEETLE
These large beetles are approximately 1 – 1/2 inches long. They have irregular white spots on their wing cover. They have white striped antennae and on the male can be twice as long as their body.
ASIAN LONGHORNED BEETLE LARVAE
The larvae is cream colored and grub-like. It is approximately 1-2 inches long when mature. Asian Longhorned Beetles bore into the tree’s sapwood
ASIAN LONGHORNED BEETLE MAPPING
This map shows the Asian longhorned beetle’s time to maturity and risk of invasion.
