Wood Destroying Organisms

This report includes a structural pest inspection embedded within the report. All observations in this report that begin with WDO are a part of a WA State Pest Inspection. Rainshadow Home Inspection employs James Lagergren, Licensed Structural Pest Inspector #94987. Please note that most WDO observations are related to high moisture conditions that could be conducive to mold-like substances. Rainshadow Home Inspection is not a mold specialist and recommends consulting with an industrial hygienist or other mold remediation expert if concerned about mold or indoor air quality.Inspection Standards in Washington State - WAC 16-228-2045 - REQUIRES THAT A DIAGRAM / DRAWING BE PREPARED FOR WOOD DESTROYING ORGANISM (WDO) REPORTS. IF THE PHOTOS AND DESCRIPTIONS IN THIS REPORT ARE INADEQUATE, A DRAWING IS AVAILABLE UPON REQUEST.

Major Concerns

  • Structure and Basement:

    (SB-1) Major Concern (WDO): This home is resting on a humble old foundation that is post and pier. Multiple structural red flags were noted during inspection that indicate repairs are needed to stabilize the home and prevent on-going settlement. Overall, post and pier foundations are more prone to settlement and seismic damage and they are nearly impossible to rodent roof. I recommend hiring a qualified general contractor to further evaluate this foundation and floor frame and implement repairs as recommended to stabilize the structure and prevent on-going settlement. Some of the urgent items include:


  • Pests and Wood Destroying Organisms:

    (PWDO-3) Repair (WDO): Understanding Anobiid Beetles and associated damage to wood: Anobiid beetles are a wood destroying organism that can significantly damage softwood. These beetles damage wood as larva emerge from infested wood. Anobiids can re-infest at any time and they favor wood with a moisture content of 13-20%. Organic control of anobiids is to implement maintenance and repairs as needed to remove damaged wood and keep wood as dry as possible. Crawl spaces below houses need to be kept properly ventilated and dry. Anobiids on exterior wood can be more complicated to control and typically require replacement of infested wood. Chemical of control can be effective but is expensive to do well and chemical control will not correct damaged wood.

    The anobiid damage to the home is throughout the perimeter of the building and the crawl space.

  • Crawl Space:

    (CS-1) Repair (WDO): Part of the crawl space could not be accessed during inspection. This area needs to be improved so that the entire crawl area can be inspected. Unfortunately this is probably not possible due to the post and pier construction. The area that I couldn't access was on the road side of the home under the laundry room.

  • Crawl Space:

    (CS-2) Repair (WDO): The plastic vapor barrier in the crawl space is incomplete. Use 6 mil black plastic to cover all exposed earth. This helps to reduce humidity and eliminate conducive pest conditions in the crawl space.


  • Pests and Wood Destroying Organisms:

    (PWDO-4) Improve (WDO): Localized wood decay fungi was noted in wood stacked next to home on the left exterior wall - I assume it is there to help rodent proof the crawl space. This should be removed.
