Inspection From a RYAN Pro

An ISA‑certified arborist will inspect your ash trees to determine their current health and whether they require emerald ash borer tree treatment.

If a tree is already infested, your arborist provides clear guidance on removal and what that entails.

Healthy trees receive preventative treatments. Your arborist selects one of three proven plant‑protection products based on the size, health, and condition of your tree.

Each treatment provides up to two years of defense against emerald ash borers. Reapplication is needed to maintain long‑term protection.

Emerald Ash Borer Treatment FAQs

The emerald ash borer is an invasive beetle that has already destroyed millions of ash trees across the Midwest. Once larvae bore into a tree’s trunk, they cut off its ability to transport water and nutrients, leading to rapid decline and death. Professional emerald ash borer treatment protects your ash trees before damage becomes irreversible, safeguarding your landscape and preventing costly tree loss.

As the Midwest’s trusted leader in tree care, RYAN uses three proven plant protection products to defend ash trees from emerald ash borers. Our ISA‑certified arborists carefully inspect your trees, determine the best treatment option, and apply it with precision. Each treatment provides up to two years of protection, giving your ash trees the best chance to thrive.

Warning signs include canopy thinning, premature leaf drop, D‑shaped exit holes in the bark, and woodpecker activity on the trunk. However, by the time these symptoms appear, it may already be too late. That’s why proactive emerald ash borer tree treatment is strongly recommended for any healthy ash tree in areas where the pest is present. A RYAN Pro can assess your trees and recommend the right plan.

DIY treatments are often ineffective and may not penetrate deeply enough to stop emerald ash borer larvae inside the tree. Some professional‑grade products also require specialized equipment and licensing. RYAN’s arborists are trained to apply treatments safely and effectively, ensuring your ash trees receive the protection they need without risk to your property or the environment.

Emerald ash borer treatment is often paired with other plant health care services such as fertilization, pruning, and disease prevention. Many homeowners also combine it with lawn care or landscaping to maintain a balanced, healthy outdoor environment.

Professional care ensures accurate diagnosis, proper timing, and long‑lasting results. RYAN’s arborists use science‑based solutions and decades of local expertise to protect your ash trees, giving you peace of mind that DIY methods simply can’t match.

Yes. Without treatment, nearly all ash trees in infested areas will eventually die from emerald ash borers. Preventive treatments every two years are the most reliable way to preserve your trees and avoid the high costs of removal and replacement.
