Emerald Ash Borer Active Flight Period
The Minnesota Department of Agriculture’s emerald ash borer (EAB) best management practice guidelines say to avoid removal of ash branches, trees and stumps May 2 through September 30 in known emerald ash borer infested areas.
If removal is necessary due to a hazardous condition then chip at least the outer 1″ of bark/wood on-site and transport to the nearest facility that can quickly process the material or transport at least the outer 1″ of bark/wood in a vehicle where it is 100 percent enclosed to the nearest facility that can quickly process the material. Material should remain enclosed until it can be at a minimum chipped.
For more information on best management practices please visit the MDA EAB website or the University of Minnesota EAB risk status website.
