Insect Intruders
Japanese Beetle Jananese beetles are commonly found in pairs
 Defoliation caused by Japanese Beetle
|
The Japanese beetle is easily identified by their metallic color. The insect's peak feeding time is from June to August. The Japanese beetle feeds on many different kinds of plants, but specifically birch, linden (basswood), crabapple, mountain ash, and roses. The beetles often eat until they leave a mere skeleton of a leaf behind. Japanese beetles are often found in groups--the large numbers of concentrated beetles can result in your tree's leaves being striped of flesh. This defoliation causes stress to the tree--sacrificing your tree's health and longevity. Treatment Options: Foilar Spray: Foilar sprays are an easy way to control the populations on Japanese beetle. If one is calling after noticing the effects of Japanese beetles this method of treatment will have to be pursued to control the live beetles. One application is generally sufficient. Average Cost: $145.00 per application Basal Drench: This is a preventative treatment and would be used preemptively against the Japanese beetle. Treatment will is completed at the base of the tree with a systemic insecticide in early spring. The tree's roots will uptake the product into the crown of the tree--when insects feed on the leaf tissue it comes in contact with the insecticide and dies. One treatment last twelve months. This treatment will help to control other harmful insects such as bronze birch borer, birch leaf miner, and emerald ash borer. Average Cost: $125.00 per annual application For more information on Japanese Beetle click HERE |
Emerald Ash Borer (E.A.B.)

Emerald Ash Borer (EAB) is an invasive species which has had devastating effects on the native ash population. EAB is in the wood borer family, in close relation with the bronze birch borer and two-lined chestnut borer. Wood boring insects invades the ash trees by chewing through the bark of the tree. Once EAB has penetrated through the bark EAB continues feeding on the vascular tissue of the tree, thus stopping the transport of ______________ throughout the tree. The earliest signs of EAB is generally wood peckers present on the tree removing bark, this process is called flecking. As the invasion continues the crown beings to thin and smaller branches begin to die.
Treatment Options: Basal Drench: This is a preventative treatment and would be used preemptively against the EAB. Treatment will is completed at the base of the tree with a systemic insecticide in early spring. The tree's roots will uptake the product into the crown of the tree--when insects feed on the leaf tissue it comes in contact with the insecticide and dies. One treatment last twelve months. This treatment will help to control other harmful insects such as bronze birch borer, birch leaf miner, and Japanese beetles. Average Cost: $125.00 per annual application Direct Inject: This treatment is for preventative or early detection of infestations. This is direction injection in the tree's vascular tissue. The advanage of this treatment over the basal drench treatment is the uptake is rapid--often taking hours, instead of weeks to get to the crown of the tree. Treatments last two years. Average Cost: $200 per biannual application. For more information on Emerald Ash Borer click HERE |
Bronze Birch Borer

Bronze birch borer is the number one killer of birch trees in Wisconsin. EAB is in the wood borer family, in close relation with the bronze birch borer and two-lined chestnut borer. Wood boring insects invades the ash trees by chewing through the bark of the tree. Once EAB has penetrated through the bark EAB continues feeding on the vascular tissue of the tree, thus stopping the transport of ______________ throughout the tree. Early signs of the bronze birch borer shows up as dead branches on the tops of trees. Bronze birch borer is not as aggressive as EAB. Bronze birch borer, unlike EAB, tends to attack already stressed trees. Unfortunately, birch trees are often stressed from being planted outside of their natural habitat for landscaping purposes. A birch tree prefers moist soil and a shaded roots. During episodes of drought birch when are stressed, watering is highly recommended.
Treatment Options: Basal Drench: This is a preventative treatment and would be used preemptively against the EAB. Treatment will is completed at the base of the tree with a systemic insecticide in early spring. The tree's roots will uptake the product into the crown of the tree--when insects feed on the leaf tissue it comes in contact with the insecticide and dies. One treatment last twelve months. This treatment will help to control other harmful insects such as bronze birch borer, birch leaf miner, and Japanese beetles. Average Cost: $125.00 per annual application Direct Inject: This treatment is for preventative or early detection of infestations. This is direction injection in the tree's vascular tissue. The advanage of this treatment over the basal drench treatment is the uptake is rapid--often taking hours, instead of weeks to get to the crown of the tree. Treatments last two years.
