Quick Answer
When inspecting seasoned firewood for signs of insects, look for visible holes, frass (insect waste), and a musty or sour smell, especially around knots and cracks in the wood.
Insect Infestation Signs
When inspecting seasoned firewood, check for holes, typically 1/8 inch in diameter, that are evenly spaced and usually in a vertical pattern. Insects like the wood-boring beetle often create these holes as they emerge from the wood. Frass, a fine powder or sawdust-like material, may also be visible around the holes or on the surrounding wood.
Seasoning and Dryness
It’s essential to properly season firewood before storing it, as this reduces the likelihood of insect infestation. Seasoning allows the wood to dry to a moisture content of 20% or lower, making it less attractive to insects. Store seasoned firewood in a well-ventilated area, covered to protect it from rain and snow. Keep in mind that different species of wood have varying BTU values and dryness rates, with some woods like oak and hickory taking longer to season than others like ash and beech.
Safety Precautions
When handling firewood, especially if you suspect insect infestation, use proper safety precautions. Wear protective eyewear and gloves to prevent injury from splinters or other debris. If you’re planning to use chainsaw equipment for felling, bucking, or splitting firewood, ensure your chainsaw is properly maintained and in good working condition. Regularly inspect your firewood for signs of insects and take prompt action if you notice any issues to avoid potential risks to your health and safety.
