In order to produce adequate heat, firewood must be "seasoned" or cured, which usually takes a year or two without kiln-heat treatment, according to the website Woodheat.org. Heat treating firewood is also performed to rid the wood of insects and other pests, especially if the wood is to be transported across state lines. The heat treatment of firewood has proved to be beneficial not only for adequate heat, but to get rid of particular insects such as the Emerald Ash Borer Beetle, which can devastate tree populations. Treating your firewood, along with proper storage and maintenance, prior to burning it in your home, can greatly reduce the chances of mold development and insect population in or around your home.
Take the wood to a kiln-heating facility and have the wood heat-treated. These facilities are equipped with kilns for heating large amounts of wood. They effectively keep the wood core temperature at a constant 180 degrees fahrenheit for two hours.
Store the wood in a cold region of your home. A garage or outside storage room are ideal locations that provide a low temperature and will impede the spread of insects or mold growth.
Vacuum the wood with a wet/dry vacuum to rid the wood of any noticeable insects. Many times spiders and other insects will find the wood and attempt to build a home. Running a vacuum over the wood will ensure that the wood stays clean and will remove any insect populations.
