Cold, frigid temperatures won’t affect the tree-killing insect known as the Emerald Ash Borer. In fact, the insect is used the cold weather. Department of Natural Resources Forest Health Specialist Bill McNee says that their native habitat in eastern Asia experiences cold winters and the pest has adapted to them. In a news release McNee said, “They are somewhat protected beneath the tree bark and many of them will survive the recent cold temperatures.” He says, “It will be a little warmer beneath the bark than the outdoor air temperature, and the wind chills do not affect them because they are sheltered.” The DNR recommends the continuance of Emerald Ash Borer management plans despite the cold weather. This includes looking for the insect in ash trees, insecticide treatment of high-value ash trees near known infestations and continues planting non-ash tree species. Also, the DNR suggests buying firewood in the local area where you plan to burn it. The Emerald Ash Borer has been found several counties in Wisconsin, including Vernon and Sauk Counties.
