White Worms in Firewood: Roundheaded Borers, No House Risk

The legless, dark-headed white larvae in your oak rounds are roundheaded borer (longhorn beetle) grubs. They infest dead/dying wood, not seasoned structural lumber.

Key Facts

• Adults may emerge up to 2 years after cutting.
• They cannot infest your home's dry framing.
• Store wood outdoors, off ground, covered, with airflow. Bring in only a few days' supply at a time.

Don't Spray

Insecticides don't penetrate wood deeply and create toxic fumes when burned. Burn older wood first. Vacuum any strays that emerge indoors.

Keep stacks away from the house to avoid termite bridges.
