Possible Deregulation of Emerald Ash Borer Restrictions Means Homeowners Must Be More Vigilant

January 2, 2019 – Wilmington, DE – The emerald ash borer (EAB) is a threat to the ash, and some other varieties of trees, across the country. They spread easily from state to state, often by the transport of firewood from area to area. Regulations have been in place for years, which support efforts to identify EAB infestations and to enforce quarantines for affected areas. These quarantines attempt to prevent travelers from carrying infected wood from an area into another area, thus spreading the insect infestation.

The USDA Animal and Plant Health Inspection Service (APHIS) has proposed removing the quarantine requirements in order to allow more resources to be used in research and development of ways to combat the spread of EAB. This proposal would put an end to site visits and also turn the nation’s focus to attempting to kill the pest via biocontrol. This method involves introducing tiny stingless wasps that prey naturally on the emerald ash borer, to impacted areas. Some of these wasps are already being used, but the measure would call for more.

The public was allowed to comment on the proposal, and these comments are now under review before a final decision is reached. Many oppose the proposal, feeling that the quarantines, while imperfect measures, bring awareness of the problem, and in some degree, at least, help keep the emerald ash borer from being spread even more quickly. Some states without quarantines rely on them to keep travelers from bringing infested wood into their forests.

Stein Tree Service is one of the companies that has been trained and certified to treat for emerald ash borer in Delaware and Pennsylvania. They know how to identify the insect, and signs of an infestation, and recommend regular inspections in areas with ash tree populations. If the proposal goes through, homeowners will need to be even more diligent and proactive on their properties to avoid losing valuable trees to this destructive pest, as well as spread the word so that others are aware of the risks.
