Dry Rot Fungus

Two species of fungi rank in the top five of wood destroying organisms (WDO).

Thrasher Termite & Pest Control can identify and eliminate these fungi and repair fungi damage. When you order a “termite report” our licensed inspectors will inspect your building and note all wood destroying pests and organisms (fungi, drywood termites, subterranean termites, damp wood termites, carpenter ants, and carpenter bees).

Wood-destroying fungi cause damage by decomposing wood studs, framing, floor joists, sub-floors, mudsills, and attic members, thereby destroying the strength of the wood holding up a house.

Meruliaporia incrassata (known as Poria)  and Serpula lacrymans (known as dry rot) are the two most common wood destroying fungi in California. Both fungi require moisture to to get started, but then may continue to spread in the absence of a moisture condition. The bad news about fungi is that they are usually hidden in places not normally seen by a homeowner. The good news is that fungi can be controlled once found. Uncontrolled, however, Poria can eat an inch of wood a day; dry rot fungus destroys more slowly, but just as thoroughly.

Prevention includes painting or varnishing exposed wood, and keeping wood from coming into contact with moisture. Leaks are an obvious source of moisture. Less obvious is wood to soil contact. Think of how a paper towel will wick up a drop of water. When wood contacts soil, it wicks up the water in the soil in a similar way and provides an ideal condition for fungi to grow.

Fungus Control

Once found, fungus should be physically removed, the area treated with an appropriate fungicide, any damaged wood replaced, and the source of moisture identified and eliminated.

A termite inspection is formally known as a Wood Destroying Organism (WDO) inspection. Our inspectors look for termites, fungus, and other pests and conditions that negatively impact the soundness of structures–that’s why we’re licensed by the Structural Pest Control Board of California.
