Emerald Ash Borer (EAB)

What is Emerald Ash Borer?

Emerald Ash Borer (EAB) is an insect that attacks all true Ash trees (Fraxinus). It is considered one of the most important forest pests of all time. It has caused the death of millions of Ash trees, and millions of dollars in treatment, removal, and lost timber value.

What is the Treatment for EAB?

Many people in our area have made the decision to pro-actively address this threat. Emamectin Benzoate has been effective in keeping treated Ash trees alive if applied every two years.  

A Time for Tough Choices

Things will change a little moving forward. There are an enormous number of untreated Ash trees on properties throughout our service area. Most of these are heavily infested and beyond treatment.

We are encouraging people to make a tough decision this season:

  • If your tree looks ok, and you want to keep it, we can give treatment recommendations.
  • If your tree is starting to look weak, the top is dead or the entire tree is dead —don’t wait.  Contact us to schedule your tree removal. The longer you wait, the more dangerous the situation becomes and the greater the cost.

Two-Lined Chestnut Borer (TLCB)

What is Two-Lined Chestnut Borer?

Two-Lined Chestnut Borer is an invasive pest that causes damage to Oak trees in our area. The borers are attracted to stressed and declining Oak trees.

Drought, poor soil nutrition, compacted soils, construction damage and physical damage to trunk and roots can cause stress to an Oak. This stress reduces the tree’s ability to transfer water and nutrient from the soil to its leaves. The Two-Lined Chestnut borer is attracted to the stressed and declining tree. 

How Do I Know If My Tree is Infested with TLCB?

A warning sign of infestation is discoloration of leaves and die-back high in the canopy. There are a number of conditions that can cause these symptoms, so it is important to get a professional diagnosis. Our experienced, Certified Arborists can accurately diagnose your tree, and recommend appropriate treatments. If left untreated, Two-Line Chestnut Borer can eventually kill the tree.

What is the Treatment for TLCB?

We recommend application of a systemic insecticide to the tree by trunk injection, soil application or basal soil drench.  It is also important to address the causes of the initial stress of the tree. Options include root zone excavation, soil amendments, mulch rings, treatment for Oak Wilt, and application of Plant Growth Regulators.  We’ll evaluate your tree’s unique situation and provide you with recommendations.

Bronze Birch Borer (BBB)

What is Bonze Birch Borer?

Bronze Birch Borer is a pest native to Minnesota and Wisconsin. They cause serious damage and death to Birch trees. In most cases, the tree dies 3-4 years after infestation.

Bronze Birch Borers are attracted to trees under stress. Stress can come from a variety of factors like prolonged drought, defoliation by leaf chewing insects, improper planting location, compacted soil and old age.

How Do I Know If My Tree is Infested with BBB?

One of the first signs of BBB is thinning and die-back high up in the canopy. Continual damage from the beetle spreads down the upper branches to the main stem of the tree.  Our Certified Arborists can evaluate your tree and provide you with an accurate diagnosis.

What is the Treatment for BBB?

We recommend application of a systemic insecticide to the tree by trunk injection, soil application or basal soil drench.  It is also important to address the causes of the initial stress of the tree. Our knowledgeable staff will tailor a specific treatment to address the unique needs of your tree.

Pine Bark Beetle

What is Pine Bark Beetle?

Pine Bark Beetles affect a wide variety of pines, and can kill if left untreated. 

Pines that are under stress are most susceptible to the beetles. It is important to keep Pines well-watered during times of hot, dry weather. It is also important to clear debris away from pines, as this removes habitat for the beetles.

What is the Treatment for Pine Bark Beetle?

We recommend application of a systemic insecticide. It is also important to address the causes of the initial stress of the tree. Our experienced, Certified Arborists will accurately diagnose the condition of your trees, and make appropriate treatment recommendations.
