Don't move firewood, prevent the spread of invasive pests and diseases

COLLEGE STATION, Texas - As fall-like weather occurs across the state, Texas A&M Forest Serviceurges all Texans to help reduce the spread of oak wilt and invasive insects by taking preventive measures and being cautious when collecting, transporting and purchasing firewood.

As Texans travel for hunting or camping trips, they may unknowingly be bringing deadly, invasive pests and pathogens along for the ride if they bring firewood with them.

"Many devastating, tree-killing pests present in Texas forests live and breed inside firewood," said Demian Gomez, Texas A&M Forest Service Regional Forest Health Coordinator. "The spread of wood borers, such as the invasive emerald ash borer, have been on the rise this year. These invasive insects have caused devastating impacts, practically wiping out entire tree species from some regions of the country."

The emerald ash borer, detected in 27 Texas counties, has killed millions of ash trees across the eastern U.S. The redbay ambrosia beetle continues to spread west from the southeast, killing redbay and sassafras trees along the way. Similarly, pathogens such as the one causing oak wilt, have killed oak trees in Central Texas in epidemic proportions.

Since insects like the emerald ash borer do not travel extreme distances naturally, it is presumed that firewood transportation was the origin of the emerald ash borer introduction in Texas which also intensified its rapid spread in the last few years. The emerald ash borer was first detected in Texas in 2016 in Harrison County. In 2024, emerald ash borer expanded to 12 new Texas counties.

Forest pests and diseases cause severe ecological and economic impacts over time. While they can spread on their own, accidental transport by humans is one of the main ways they move greater distances, sometimes quickly jumping state and county lines. Firewood is the common way many of these pests are moved. Even wood that looks clean and healthy may still have insect eggs or fungal spores that can start new infestations.

"We can limit the spread of invasive tree pests," said Gomez. "The best rule of thumb is to burn the firewood near where it's bought or picked up. Moving firewood can easily introduce insects and diseases to new areas, particularly during hunting and camping seasons."

For diseases like oak wilt, this is critical. Transporting and storing infected wood from red oaks can spread oak wilt fungal spores to previously uninfected neighborhoods and properties. Because live oaks tend to grow in large, dense groups, oak wilt spreads quickly, and one infected tree can lead to large patches of dead and dying trees.

While firewood is an important commodity in the fall and winter, Texans can help prevent the spread of these pests and diseases by purchasing, collecting and burning firewood locally.
