Garland, TX – The threat of an invasive beetle, the emerald ash borer (EAB), has reached neighboring counties, raising concerns for local tree health in Garland and surrounding areas. Recently identified in Rockwall County, this pest is known for its devastating impact on ash trees, and experts warn that its presence could soon be felt in Garland if residents do not take precautions.
According to a report from the Texas A&M Forest Service, the EAB has now been confirmed in five Texas counties, including Rockwall, Jack, Navarro, Somervell, and Bell. This follows previous identifications in Collin County and Hopkins County in recent years. The EAB, which is native to northeastern Asia, poses a significant threat to ash trees, as its larvae feed on the phloem, obstructing the flow of nutrients and ultimately leading to the tree’s death within five years if left untreated.
Residents and tree owners in Garland are advised to be on the lookout for symptoms of EAB infestation. Key indicators include:
- Dead branches near the top of the tree.
- Leafy shoots sprouting from the trunk.
- Bark splits that expose S-shaped larva tunnels.
- D-shaped exit holes in the bark.
Fully grown EAB are characterized by their dark emerald green color, measuring about half an inch long and an eighth of an inch wide. They are most commonly observed near ash trees during the months of May and June.
“EAB is one of the worst invasive insects to impact North American forests,” stated Allen Smith with the Texas A&M Forest Service. “The expansion of EAB across the state has been accelerated by human activities, such as the transportation of infected firewood and ash tree products.”
In response to this growing threat, the Texas Department of Agriculture is expected to implement a quarantine in affected counties. This measure will restrict the movement of ash materials, including firewood, mulch, and nursery stock, in an effort to curtail the spread of the beetle.
“Because EAB is often unintentionally transported on wood products, the quarantine will help slow its spread,” explained Demian Gomez from the Texas A&M Forest Service. “We encourage Texans to burn firewood where it is purchased to prevent further dissemination of the beetle.”
Additionally, experts recommend that residents take proactive steps to reduce potential breeding grounds for EAB. One effective strategy is to diversify tree and plant species on properties by following the 10-20-30 rule: ensuring that no more than 10% of plants belong to the same species, 20% to the same genus, and 30% to the same family.
As the threat of the emerald ash borer looms closer, Garland residents are urged to remain vigilant and informed. For updated information on managing EAB, residents should turn to the Texas A&M Forest Service. Furthermore, if you observe any symptomatic ash trees, please report them by calling the EAB hotline at 1-866-322-4512.
