Don't risk starting a new infestation of an invasive insect or disease. You have the power to save trees.

Obtain firewood near the location where you will burn it – that means the wood was cut in a nearby forest, in the same county, or a maximum of 50 miles from where you'll have your fire.
Don't be tempted to get firewood from a remote location just because the wood looks clean and healthy. It could still harbor tiny insect eggs or microscopic fungal spores that will start a new and deadly infestation of forest pests.
Aged or seasoned wood is not considered safe to move, but commercially kiln-dried wood is a good option if you must transport firewood.
If you have already moved firewood, and you need to dispose of it safely, burn it soon and completely. Make sure to rake the storage area carefully and also burn the debris. In the future, buy from a local source.
Tell your friends and others about the risks of moving firewood – no one wants to be responsible for starting a new pest infestation.

Planning to move from a State infested with gypsy moth to one that is not infested? Moving your camper or recreational vehicle across State lines?

Inspecting your personal property for gypsy moths goes beyond being a good neighbor: it is required by law. Don't be responsible for moving an old pest to a new neighborhood.
