Wood Destroying Organisms


Wood Destroying Organisms are a group of pests that can cause significant structural damage and directly impact the structural integrity of a home.  WDOs are an important part of the natural cycle of decay in forests and other natural areas to help break down cellulose from dead trees and other organic material, eventually returning this material to the soil where it is used by new growth. However, when they direct their attention to the wood of a home rather than a dying tree, this can lead to extensive problems.  Left undetected and/or untreated, WDO's can create an expensive, hazardous situation.  Damage from these organisms could result in devaluation of a property/structor or substantial costs for repairs.  

What Are We Looking For?


Subterranean Termites are the most common found in the U.S. and most prevalent in the state of Ohio.  Termites feed on materials that contain cellulose-such as wood. 

Carpenter Ants

Carpenter ants are among the largest ants occurring in the U.S.  Unlike Termites, they do not eat wood, instead they excavate galleries to create nest sites

Other Pests

Carpenter Bees

Powderpost Beetles

Bark Beetles

Ambrosia Beetles

Horntail Wasps

Wharf borer

Wood-Dest. Fungi

  3. Keep foundation vents open and crawlspaces well ventilated to lower wood moisture content.
