Oakdale’s Battle Against the Emerald Ash Borer: How Strategic Tree Trimming Becomes Your First Line of Defense

The emerald ash borer (EAB) has become one of the most destructive invasive pests in North American history, and Oakdale, New York is no exception to this growing threat. This tiny green beetle has killed tens of millions of ash trees across North America, with hundreds of millions of rural and urban ash trees already destroyed. For Suffolk County homeowners, understanding how strategic tree trimming can help combat this invasive pest is crucial for protecting their valuable ash trees and maintaining their property’s health and safety.

Understanding the Emerald Ash Borer Threat in New York

EAB was first discovered in New York State in 2009 and has been confirmed in all New York counties except Hamilton and Lewis, with all of New York State’s native ash (white, green, and black) at risk. The serpentine feeding galleries of the larvae disrupt the flow of nutrients and water, effectively girdling and killing the tree. Once infested with EAB, most ash trees die within 2-4 years.

According to NewYorkUpState, there are 900 million ash trees in New York, which is about 7% of the state’s total tree population. However, ash trees have been dying rapidly over the past few years, making proactive management essential for Suffolk County property owners.

The Role of Strategic Tree Trimming in EAB Defense

Strategic tree trimming plays a vital role in emerald ash borer management, though it must be approached with careful timing and expertise. Pruning cuts can send signals of stress to pests. If possible, avoid pruning ash trees during the summer months when adult EAB beetles are most active (May-September).

By postponing pruning until the fall, you can help reduce the risk of EAB spreading. If the tree is left intact during the EAB Active Period, it can provide habitat for EAB adults to lay eggs. But since the adults won’t emerge until the following year, if this tree or branch is cut and properly disposed of during the EAB Dormant Period, any EAB that may exist in the ash material will be destroyed when the wood is destroyed.

Professional tree trimming oakdale services understand these critical timing considerations and can help property owners make informed decisions about when and how to trim their ash trees safely.

Best Practices for EAB-Conscious Tree Trimming

The low activity period for emerald ash borer typically begins in November and runs through April. This dormant period provides the safest window for tree trimming activities. Only the outer 1″ of bark/wood harbors EAB. If this material is removed, the remaining wood may be utilized as desired and does not need to be destroyed.

However, proper disposal is crucial. Cutting up trees infected by EAB for lumber, firewood or tree trimming and transporting the infected wood to new areas will transport the EAB to infest and kill trees in these areas. Do not transport any wood or brush from EAB killed trees.

When Treatment Trumps Trimming

While strategic trimming is important, it’s not always the complete solution. Research suggests that insecticide treatments are significantly more effective on EAB-infested ash trees with less than 50% canopy thinning. If your tree still has approximately 60% of its canopy alive then treatment can be very effective and should be seriously considered. Once canopy dieback has passed the 30-40% range, however, treatment success is unlikely because the tree’s ability to move water (and thus other resources) through its system is seriously compromised.

This is why it is important to begin preventively treating trees you really want to protect when EAB is detected within 15–30 miles of your location. The objective is to protect the trees before the beetles arrive.

The goal isn’t just keeping trees alive—it’s maintaining them as valuable property assets while eliminating safety risks that keep homeowners awake during storm season. Trees add tremendous value to Suffolk County properties, but they also represent significant risks when not properly maintained. Long Island’s coastal location means trees face constant stress from salt air, strong winds, and severe weather events that have doubled in frequency since 1980.

The Importance of Professional Expertise

Have your tree structurally assessed and then get a treatment quote from a certified arborist. Lately we have seen structurally compromised ash trees being treated by companies outside of the tree care industry. Professional tree services understand that while silvicultural control tactics alone will not be an adequate management strategy, tree removal is an important component of both a broader pest management program and the systematic replacement of ash canopies in urban forests. Increasing understanding of the efficacy of different management techniques in slowing population growth of emerald ash borer will be useful to support decision–making by land managers.
