A relatively new problem associated with wood heat is the movement of invasive pests in firewood. Most of the cases of pests being transported in firewood involve it being brought to campgrounds, not for home heating. 1 Regardless, safeguards are being developed to minimize the transportation of invasive species, such as the emerald ash bore or the asian longhorn beetle, from overseas and within the US. The US Department of Agriculture Animal Plant Health Inspection Service (APHIS) is responsible for addressing the problem. Laws requiring large-scale commercial firewood producers to heat treat firewood in a kiln or efforts to control shipment of logs over long distance can help, but the job is much too big for APHIS alone. Un-paralleled cooperation amongst producers of firewood, the forestry community, agencies and the consuming public will be necessary to avoid what a city forester from Detroit, where the majority of local ash trees have succumbed to the emerald ash borer, called "a slow motion tornado." 2 Governmental websites aimed at educating stove users on clean burning techniques should also provide information and resources on how to control invasive pests.
