Expert Tree Insect Control: Identify and Manage Harmful Pests

Tree insect control is a vital part of maintaining a healthy, beautiful landscape in Wisconsin. At Wachtel Tree Science, our ISA Certified Arborists provide science-based solutions to identify, prevent, and treat harmful infestations. By addressing insect issues early, we help protect your trees from structural decline and the potential death of the plant.

Harmful tree pests do more than just create visible damage — they cause significant physiological stress. This stress reduces a tree’s natural defenses, increasing the likelihood of substantial decline. Our team specializes in tree insect control for familiar Southeastern Wisconsin threats, such as invasive species like the Emerald Ash Borer or more common pests like leafhoppers, aphids, and scale.

Wachtel’s tree care professionals possess the specialized knowledge required to prevent infestations and implement treatment methods that sustain tree health throughout the year.

Frequently Asked Tree Insect Control Questions

How do you get rid of a bug infestation in a tree?

To effectively get rid of a tree insect infestation, you must first identify the specific pest. Our ISA Certified Arborists use scientific tree insect control methods like soil systemic treatments and trunk injections to eliminate tree pests at the source without harming the tree’s health.

What can I spray on my trees to keep bugs away?

Professional spray programs are the most effective way to keep bugs away. At Wachtel Tree Science, we use carefully timed sprays based on specific insect life cycles. This ensures we are treating trees exactly when they are most vulnerable to pests like leafhoppers and scale.

What insecticide kills tree boring insects?

Tree boring insects, such as the Emerald Ash Borer, are best controlled using specialized trunk injections or soil systemic insecticides. Because these pests live inside the wood, surface sprays are often ineffective. Our scientific injection methods deliver the treatment directly into the tree’s vascular system instead.

How much do tree injections cost?

The cost of tree injections varies based on the size (diameter) of the tree and the type of insect being treated. While DIY methods might seem cheaper, professional injections are a long-term investment that can save you the much higher cost of tree removal and/or replacement.

Can spices or home remedies keep tree bugs away?

While some bugs may be deterred by certain spices, home remedies are generally ineffective for large-scale tree insect control in Wisconsin. Professional, research-based treatments are necessary to manage aggressive invasive species and ensure the structural integrity of your landscape.
