Protect trees and shrubs with timely, professional treatment

When insect activity or disease pressure goes untreated, the landscape can decline in ways that affect both plant health and overall appearance. RYAN provides professional insect and disease control designed to respond to active issues, limit further damage, and support healthier long-term performance across trees, shrubs, and other vulnerable plantings throughout the property.

Tree and Shrub Evaluation

A RYAN specialist evaluates trees and shrubs for visible symptoms, insect activity, disease pressure, and environmental conditions that may be contributing to decline.

Treatment begins with identifying what is affecting the plant so recommendations can be matched to the actual issue, not just the visible symptoms.

RYAN builds a treatment plan around the affected plants, the type of insect or disease pressure present, and the timing needed for the best response.

Professional tree insect control and disease treatments are applied with precision to help stop progression and protect plant health.

When conditions call for it, preventive treatments can help reduce the risk of recurring insect or disease issues across vulnerable trees and shrubs.

RYAN continues to watch how plants are responding so treatment stays aligned with changing conditions and long-term landscape health.

Insect & Disease Control FAQs

Disease and tree insect control services protect your trees and shrubs from harmful pests and infections that can weaken or even kill them. When left unchecked, issues like emerald ash borer, bagworms, or fungal diseases can spread quickly, causing costly damage and loss. Professional insect and tree disease treatment stops these threats early, safeguards your investment, and ensures your landscape stays healthy and beautiful.

As the Midwest’s trusted leader in tree and shrub care, RYAN provides customized treatment plans tailored to your property and its landscape features. Our ISA‑certified arborists and licensed specialists use research‑based methods to accurately diagnose problems and apply targeted treatments. We don’t just mask symptoms; we eliminate pests, stop diseases, and restore long‑term health to your plants.

Warning signs include chewed or discolored leaves, thinning canopies, premature leaf drop, visible insects, and unusual spots or growths on leaves and bark. If you notice these symptoms, a RYAN Pro can perform a thorough inspection and recommend the right treatment plan.

Although DIY sprays and treatments are available, they’re often ineffective, misapplied, or unsafe for certain plants. Some infestations, like emerald ash borers, require specialized equipment and applications. RYAN’s professionals are trained to identify the exact issue and apply treatments safely and effectively, ensuring your plants get the right care without risk to your property or the environment.

Disease and tree insect control often works alongside services like fertilization, pruning, and plant health care programs. Many homeowners also combine it with lawn care or landscaping to create a healthier, more balanced outdoor environment.

Professional care ensures accurate diagnosis, precise treatment, and long‑lasting results. RYAN’s arborists use science‑based solutions and decades of local experience to protect your trees and shrubs, giving you healthier plants and peace of mind that DIY methods rarely achieve.

Not every plant requires frequent treatments, but most benefit from proactive monitoring and preventative care. Preventive services help stop infestations and diseases before they cause serious harm, saving you time, money, and stress. Your RYAN Pro will provide honest guidance on whether your trees and shrubs need regular treatments or occasional check‑ups.
