Emerald ash borer is commonly transported in ash products like firewood, other wood products, and nursery stock. Firewood is likely the probable number one vector that has been responsible for long distance movement of emerald ash borer.

Emerald ash borer is a federally regulated pest whose detection results in quarantines.

The regulatory goal of the emerald ash borer program is to stop the artificial spread of emerald ash borer while impacting as few stakeholders as possible to allow time for our scientists and researchers to develop additional tools for use in managing emerald ash borer infestations.

Effective immediately a quarantine within Merrimack County is in place on the following regulated articles:

  • All life stages of the emerald ash borer
  • Hardwood firewood
  • Fraxinus (ash) nursery stock
  • Fraxinus (ash) green lumber
  • Fraxinus (ash) logs
  • Any other Fraxinus (ash) material, living, dead, cut, or fallen, including chips, stumps, branches, roots and debris
  • Woodchips consisting in any part of Fraxinus (ash) chips
  • Any article, product, or means of conveyance not listed above if an authorized state inspector determines that it presents a risk of spreading emerald ash borer.                             
  • These regulated articles cannot be moved outside of Merrimack County unless certified to meet conditions that mitigate the risks associated with these products.  
  • These regulated articles can move freely within Merrimack County without needing any further permitting or certification.
  • These materials originating in any other New Hampshire county are not regulated at this time, unless they are moved into Merrimack County at which point they will become regulated articles unless they meet specific requirements for safeguarding from infestation by emerald ash borer.
  • These materials originating in any non-quarantined county may transit through Merrimack County without becoming regulated articles as long as they are safeguarded from infestation by emerald ash borer en-route, and are accompanied by documentation as to point of origin and point of destination.
  • Regulated articles can be transported out of Merrimack County with a compliance agreement with NHDAMF for intrastate transport, or USDA APHIS for interstate transport, if it can be shown that the materials have been treated or will be treated in a way that mitigates the risk of artificially spreading emerald ash borer. There are options for treatment for ash wood products, but not for nursery stock. Acceptable treatment and handling options that will enable a compliance agreement for movement of these materials include:
  • Removal of bark and additional ½ inch of wood
  • Kiln sterilization treatment
  • Fumigation treatment
  • Heat treatment to a core temperature of 60° C for 60 minutes
  • Chipping materials to a size of less than 1 inch in two dimensions
  • Heat treat ash lumber in wood packing material to ISPM-15 standards
  • Safeguarding material from infestation and movement only during the EAB non-flight period of October 1 – May 1 and to a receiving facility that has a compliance agreement for processing these materials.

For the next month, there will be opportunity to provide comment on the EAB quarantine at public and stakeholders meetings. The public comment period will close on May 8th, and a revised quarantine may be issued at that time. Please see www.nhbugs.org for a copy of the quarantine, a schedule of public meetings, how to submit comments on the quarantine, and specifics regarding compliance agreements.
