Why Powder Post Beetle Treatment Is Critical After Flooding—Before New Insulation Goes In
The recent flooding across Whatcom and Skagit Counties has caused widespread water intrusion in homes—especially crawl spaces, basements, and wall cavities. While most homeowners and contractors are focused on drying, cleanup, and insulation replacement, there’s a hidden threat that often gets overlooked:
Powder post beetles.
Flooding Creates the Perfect Conditions for Wood-Destroying Insects
Powder post beetles thrive in moist, untreated wood. After flooding, framing members, subfloors, sill plates, and joists often retain elevated moisture levels—even after surface drying. This damp environment is exactly what powder post beetles need to infest, lay eggs, and begin slowly destroying wood from the inside out.
Once insulation is installed, these infestations can go undetected for years, quietly compromising structural integrity and leading to costly repairs down the road.
Why Treatment Must Happen Before Insulation Installation
Installing new insulation without addressing wood-destroying insects is like sealing in a problem you can’t see.
A professional powder post beetle treatment:
- Targets beetles and larvae already present in the wood
- Helps prevent future infestations attracted by post-flood moisture
- Protects exposed framing before it’s concealed
- Saves homeowners from tearing out brand-new insulation later
Once insulation is installed, access to affected wood becomes limited or impossible without demolition.
