Abstract: Elm firewood storage in urban areas often conflicts with Dutch elm disease control efforts because of the biological hazard associated with elm bark beetle emergence. To demonstrate that polyethylene coverings form an effective barrier against elm bark beetle flight, an elm firewood demonstration program was initiated in Madison, Wisconsin on April 6, 1981. Fourteen, one-half cord, elm firewood piles were covered and sealed with either clear, four or six mil polyethylene, or black, six mil polyethylene or left uncovered. Results showed that clear, six mil polyethylene effectively prevented elm bark beetle flight and as an added benefit also lowered wood moisture content more than black polyethylene covered piles and uncovered piles. Homeowners who use elm wood for fuel should be encouraged to cover the wood with clear, six mil polyethylene during the period of bark beetle activity.
