Wood-destroying organisms (WDOs), such as termites, carpenter ants, wood-boring beetles, and decay fungi, can cause serious structural damage to homes and other wood-framed buildings if left unchecked. Getting a wdo inspection by a trained professional at least once a year is one of the best ways to protect your property investment and prevent costly repairs down the road.
In this blog post, we'll discuss the importance of WDO inspections, what happens during an inspection, signs of WDO infestation, treatment options, and tips for preventing infestations in your home.
Why Annual WDO Inspections Are Critical
WDOs like termites and carpenter ants live in colonies that can grow exponentially if given the chance. A termite colony numbering in the tens of thousands is not uncommon in infested homes. These insects can seriously compromise the structural integrity of a home by burrowing through and eating away at wooden structural elements like wall studs, floor joists, rafters, and siding.
Decay fungi and wood-boring beetles also damage wood over time. Left undetected and untreated, WDO damage can become extensive and extremely expensive to repair. Having an annual wdo inspection performed by a licensed professional helps detect infestations early, before they get out of hand. Detecting them in the early stages makes treatment more effective and less disruptive to the home.
During a WDO inspection, the inspector will check all areas of the home for signs of infestation, not just the visibly accessible areas. They have the tools and know-how to probe wood structures and recognize damage. Catching an infestation early could save thousands in repairs down the road.
What to Expect During a WDO Inspection
A thorough WDO inspection typically takes 1-2 hours for a single family home. The inspector will examine both the interior and exterior of the home, including the roof, foundation, and any wooden structures in close proximity to the home like decks, sheds and fences.
Here are some of the main activities during a standard WDO inspection:
Visually inspect all accessible wood elements in the home, including siding, support beams, joists, subflooring, wooden doors and window frames, trim, and cabinetry for signs of damage. Probe any questionable areas with a screwdriver or other tool.
Carefully examine areas known to be vulnerable to WDOs, such as bathrooms, kitchens, and laundry rooms where there is excess moisture. Inspect where wood elements contact the foundation or soil.
Inspect the exterior of the home and outbuildings for mud tubes or shelter tubes constructed by termites. Tubes are a clear sign of active infestation.
Remove insulation in select areas to check for hidden damage behind walls, in crawl spaces, and inside support beams.
Use moisture meters and probes to test wood in areas that may not be visibly accessible.
Thoroughly inspect crawl spaces, basements, attics, and unfinished areas for compromise.
Identify any conducive conditions that can attract WDOs, such as high humidity, excess wood debris, standing water, tree branches touching the home.
Provide a detailed report summarizing all findings and outlining any recommended treatment if signs of infestation are found.
The more thorough the inspection, the better protection for your home. Only trained and licensed professionals have the expertise to conduct a comprehensive WDO check.
Signs of WDO Infestation
Inspectors look for a variety of signs during WDO inspections. Here are some of the most common indicators of termite, carpenter ant, beetle, and fungal damage they will be on alert for:
Mud Tubes / Shelter Tubes: Long, narrow mud tubes are constructed by termites to provide protected passageways between their colony and food sources. Tubes travelling up foundation walls or pier supports are a major red flag.
Hollowed Wood: Termites bore through wood from the inside out, leaving a thin outer shell of wood fibers intact at first. Tapping wood with the handle of a screwdriver can reveal areas that sound hollow.
Frass: Sawdust-like material called frass is leftover from termites chewing through wood. It can often be found in small piles around infested areas. Carpenter ants also leave a more granular frass behind.
Swarmers: Seeing winged ants or termites inside the home indicate an active infestation warranting immediate treatment. These swarmers are reproductive members of the colony released to start new colonies.
Wood Damage: Carefully examine all structural wood for damage. Look for wood that appears etched, tunneled, or eaten away. Soft areas that can be pierced with a small probe often indicate damage.
Sagging Floors: If floor joists have been severely compromised by termites, noticeable sagging or uneven floors can occur.
Leaky Plumbing: Carpenter ants are attracted to excess moisture and will gnaw through wood to enlarge existing leaks, causing more damage.
Fungal Growth: White filaments and mushrooms growing on damp wood are evidence of decay fungi breaking down the integrity of the wood over time.
Finding any of these signs means a WDO infestation is likely present and should be treated as soon as possible. The inspector may recommend improving ventilation or correcting excess moisture issues that make the home conducive to WDOs.
Treatment Options for WDO Infestations
If your home inspector confirms WDO activity, the next step is getting the infestation eliminated before the pests can multiply and cause major structural damage. There are several common treatment options, including:
Liquid and Foam Insecticides: Powerful liquid termiticides can be injected into wood framing, masonry voids, soil, and other areas where termites are active. This creates a treated zone preventing them from infesting the building. Foams provide similar protection.
Termite Baits: Bait systems lure termites to a toxic food source that they eat and share with the rest of the colony. The bait gradually eliminates the entire colony from the inside out.
Wood Repairs and Replacement: Heavily infested or damaged wood may need to be replaced to restore structural integrity.
Fumigation: This involves tenting the entire home and pumping in a gas to penetrate infested areas and exterminate entire colonies. It is the most thorough treatment option when done properly.
Topical Sprays and Dusts: Low toxicity insecticide sprays and dusts can be used in building voids and crawl spaces to repel and control WDOs when infestations are minor. Periodic reapplication is required.
A combination approach is usually required to eliminate an existing infestation and provide ongoing prevention. A reputable pest control company or exterminator will recommend the best solution based on the specifics of your home and the scope of damage.
Tips for Preventing WDO Infestations
While annual inspections and prompt treatment are the best defense once an infestation is present, there are some DIY maintenance and prevention measures you can employ:
Keep firewood, building materials, and wood debris at least 20 feet away from the home's foundation. Don't give termites an easy food source.
Eliminate excess moisture by repairing leaky plumbing, improving ventilation in damp areas, diverting rain runoff, and keeping gutters and downspouts clear.
Routinely inspect the home exterior yourself for potential signs of infestation like mud tubes or insect wings.
Have trees and shrubs trimmed back from touching the home. Prune any branches that contact or overhang the roof.
Store cardboard boxes and other cellulose containing materials off concrete floors and away from soil contact.
Consider using solid concrete footer barriers with pressure treated starter boards around the base of wood-framed homes.
Keep home insulation levels adequate and repair cracks in the foundation walls and slab to deter WDO entry.
Replace decaying exterior wood, leaky door/window seals, and faulty grading/drainage.
With diligent prevention and early monitoring, costly WDO damage can be avoided. But don't neglect having a trained professional conduct a thorough wdo inspection at least annually. Catching an infestation in the early stages is critical to effective treatment and preserving your property's structural integrity. Maintaining proper documentation of all inspections and treatments is also key.
The Importance of Using a Licensed, Skilled Inspector
When it's time for your yearly WDO inspection, be sure to use only licensed, trained professionals with extensive hands-on experience. All states require WDO inspectors to meet certain licensing requirements demonstrating their competence. There is simply no substitute for expertise when it comes to protecting your home from wood-destroying organisms.
In addition to checking for signs of infestation, a skilled inspector will also be able to provide advice on correcting any conditions around the home that could invite WDOs in. They have the depth of knowledge to make recommendations on the most effective treatment options for elimination and prevention in line with your specific situation. Don't leave it to chance - work with trained experts to safeguard your property.
WDO Inspections in Current Market Conditions
Real estate demand has surged in recent years, leading to cutthroat competition and homes selling rapidly, often sight-unseen. But this frenzied market makes thorough, professional wdo inspections more crucial than ever before. Sellers should not neglect these inspections prior to listing their home. Likewise, smart buyers will make WDO inspections a firm contingency before completing a home purchase.
Left unchecked, WDO damage can cost many thousands of dollars to remediate down the road. Failing to disclose known infestations to buyers can also open sellers up to major legal liabilities. And buying a home with hidden WDO damage becomes the unaware buyer's expensive headache to fix.
In hot markets, some buyers are tempted to waive inspection contingencies to make their bid more attractive. This is extremely risky where WDO and pest inspections are concerned. Termite treatments alone often run $1,500-$3,000 or more. Then factor thousands more to repair structural damage if critical infestations go undetected.
A pre-listing inspection identifying any issues early allows the seller to treat and make repairs prior to sale. The buyer still benefits from the knowledge that proper prevention was implemented. Waiving the WDO inspection contingency can saddle buyers with massive, unexpected repair costs.
Bottom line: professional WDO inspections should remain a non-negotiable for both sellers and buyers, even in frenzied markets. Catching problems early before they become hugely expensive fixes is well worth the peace of mind for all parties.
Implications of WDO Inspection Findings
If a wdo inspection uncovers signs of infestation, what happens next? The implications and recommended actions will depend on the severity of the situation discovered:
Minor/Early Stage Damage: If caught very early, the damage may be relatively minor and localized, like a small carpenter ant nest or termite Shelter tubes in one section of the home. Spot treatments can often take care of these issues.
Moderate/Spreading Damage: More extensive tunnels, dormant frass, and sections of etched wood may indicate spreading WDO activity warranting larger-scale treatment like wall void injections combined with bait stations for broader protection.
Major Structural Damage: If WDOs have already substantially damaged large sections of floor joists, wall studs, and other critical framing, major repairs involving replacing wood framing will be necessary after addressing the active infestations.
Damage Uncovered During Renovations: It's common for previously hidden WDO damage to be found when renovating or updating a home. This often expands the scope of work and budget substantially.
Reinfestation: If there are signs of WDOs returning despite previous treatment, the underlying conditions allowing infestation may need correction along with retreatments.
No Apparent Infestation: The inspection finds no identifiable damage and no evidence of current WDO activity. Preventative treatment may still be recommended. Continued vigilance with future inspections is advised.
The extent of damage and how long activity has persisted impact the scale of treatment and repairs needed. Early detection from regular inspections provides the best odds of minimizing costs. Even after treatment, ongoing inspections are prudent to ensure infestations do not reoccur.
Closing Thoughts
WDOs pose a severe, but often preventable threat to the structural integrity and value preservation of homes in many regions. Left unchecked, seemingly small infestations can escalate into thousands of dollars of critical repairs and even structural failure. Make annual professional wdo inspections a priority for early detection and prompt treatment before costs spiral out of control. With proper diligence, WDO damage can be avoided and peace of mind maintained.
Stay vigilant! Be proactive! Protect your valuable property investment against wood-destroying organisms through education, maintenance, and quality inspections by experienced professionals you can trust. Don't become another preventable WDO statistic when the solution is as straightforward as an annual checkup. Your future self will thank you.
