Emerald Ash Borer in New Brunswick: Regulated Areas, Treatment and Removal

What Is the Emerald Ash Borer and Why Is It a Threat in New Brunswick?

The emerald ash borer (EAB) is an invasive beetle that has devastated ash tree populations across North America since its discovery in 2002. This metallic green insect, native to Asia, targets ash trees of all species and sizes, and its larvae feed on the inner bark, disrupting the tree's ability to transport water and nutrients. In New Brunswick, the emerald ash borer has become a significant concern for property owners, arborists, and forest managers alike.

Once an EAB infestation takes hold, the consequences are severe. Infested ash trees typically die within two to four years of initial colonization. The beetle's lifecycle means that a single ash tree can host thousands of larvae, each one creating galleries beneath the bark that eventually girdle the tree. For homeowners in Moncton and the surrounding area, this threat makes early detection and professional intervention essential to protecting valuable ash trees on residential properties.

Recognizing the Signs of Emerald Ash Borer Infestation

Identifying an EAB infestation early can make the difference between saving a tree and losing it entirely. One of the most distinctive signs is the presence of D-shaped holes in the bark, which are typically about 3 to 4 millimetres in diameter. These exit holes are created when adult beetles emerge from the tree in late spring or early summer. If you notice these characteristic D-shaped holes on your ash tree, immediate professional assessment is warranted.

Beyond the exit holes, watch for other warning signs that your ash tree may be infested or dying. Canopy dieback, where branches progressively lose their leaves starting from the top of the tree, is a common indicator of advanced infestation. Ash trees may also exhibit epicormic sprouting, which is the sudden growth of shoots along the trunk and main branches. Bark cracks and peeling, combined with increased woodpecker activity (as birds feed on the beetle larvae), are additional red flags.

Regulated Areas and Movement Restrictions for Ash Wood in New Brunswick

New Brunswick has established regulated areas to slow the spread of the emerald ash borer and protect uninfested regions. Understanding these regulations is crucial if you own ash wood or plan to move firewood, lumber, or other ash materials. The provincial government works with the Canadian Food Inspection Agency to enforce movement restrictions on ash wood and ash products originating from areas where EAB is present or suspected.

Ash firewood movement rules in New Brunswick prohibit the transport of untreated ash firewood and ash wood products from regulated areas into unregulated areas without proper certification or treatment. If you have ash firewood or plan to purchase it, verify that it comes from a compliant source or has been heat-treated according to provincial standards. These restrictions exist to prevent accidental spread of the beetle to new territories. Failure to comply with ash wood movement regulations can result in fines and contribute to the further spread of this destructive pest. For current information on regulated areas, consult the Government of New Brunswick Agriculture division.

Treatment Options for Ash Trees Threatened by EAB

If your ash tree shows early signs of infestation or is located in a high-risk area, professional treatment may be possible. Several insecticidal treatments are available to protect ash trees from emerald ash borer, including trunk injections and bark sprays. These treatments work by introducing pesticides into the tree's vascular system or applying them to the bark surface, where they kill larvae and adult beetles. However, treatment is most effective when applied before infestation occurs or in the very early stages of colonization.

The decision to treat an ash tree depends on several factors: the tree's overall health, its location and value to your property, the extent of any existing infestation, and the cost of treatment relative to Tree Removal. Treatment typically requires annual or bi-annual applications, which means ongoing expense and commitment. Our certified arborists at Hub City Tree Trimming can assess your ash tree and recommend whether treatment is viable or whether removal is the more prudent option. To save an ash tree, early intervention combined with proper monitoring is essential. We encourage property owners to act quickly: call (506) 805-0418 to schedule a free estimate.

When Ash Tree Removal Becomes Necessary

A dying ash tree that is heavily infested with emerald ash borer, structurally compromised, or posing a safety risk to your home or property should be removed professionally. Tree Removal is often the most practical and cost-effective solution for ash trees in advanced stages of EAB infestation. Removing an infested tree prevents the beetle population from spreading to neighbouring ash trees and eliminates the hazard of branch failure or tree failure during storms.

Professional Tree Removal services ensure that the tree is safely felled, the stump is properly managed, and the wood is disposed of or chipped according to regulations. In some cases, the removed wood can be chipped on site for mulch, provided it is not transported beyond your property. Hub City Tree Trimming has the equipment and expertise to remove ash trees of any size safely and efficiently. Once the tree is removed, you may choose to plant a replacement species that is not susceptible to EAB, such as a native oak or maple. Our team can discuss replanting options during your consultation.

Protecting Your Property: Prevention and Professional Support

The best defence against emerald ash borer is a proactive approach. Monitor your ash trees regularly for signs of infestation, particularly during late spring and early summer when adult beetles are active. Maintain tree health through proper watering and care, as stressed trees are more vulnerable to beetle colonization. If you live in or near a regulated area, avoid bringing untreated ash firewood or ash materials onto your property from outside sources.

Professional arborists play a vital role in EAB management. Our team at Hub City Tree Trimming stays current on the latest emerald ash borer research and treatment protocols. We can perform regular inspections, recommend preventive measures, and guide you through the difficult decision of whether to treat or remove an affected tree.
