For those who heat partially or entirely with firewood, sometimes it isn't easy to procure enough from your property to meet the need for the winter season. In these cases, we are often left with the option of purchasing firewood. Sometimes this results in the firewood coming from a few counties away due to extreme demand, especially towards the end of the season.
The Virginia Department of Agriculture and Consumer Services has a good press release from earlier this fall explaining why this is a bad idea and the issues that can result. Lots of pests and infestations can spread via firewood transfer. Keep it local, and help reduce the spread of forest and ag pests.
