Why the crawl space matters
Most Asheville homes have a crawl space, and the crawl space is where the pest problems start. It is damp — Asheville gets about 41 inches of rain a year, and the ground under the house holds the moisture. It is dark. It is full of wood: the sill plates, the subfloor, the joists. And nobody looks in it. A termite colony can feed in a crawl space for a season or more before anyone notices, a mouse run can cross it every night, and a palmetto bug can live in it for months.
The crawl space is also where the conditions are set. A damp crawl space draws termites and carpenter ants. A crawl space with wood in contact with soil gives termites a direct route. A crawl space with gaps at the vents and the pipe entries gives mice and roaches a way in. The inspection starts here for a reason.
What the inspection finds
Mud tubes on the foundation and the piers. Wood that sounds hollow when tapped. Moisture readings that run high where the ground is wet. Droppings along the runs. Entry points at the vents, the pipe entries and the gaps in the foundation. Standing water after rain, and the grading that lets it in. The inspector takes photographs of what is found and records the moisture readings, because the crawl space is the part of the house the homeowner never sees — and the photographs are the only way to show it.
What the work involves
The work starts with the moisture: gutters cleared, downspouts extended, grading that falls away from the wall, and the crawl space dried and ventilated. Then the entries are sealed — vent covers, gaps at the pipe entries, the foundation gaps that mice use. Then the treatment follows what was found: a soil treatment or bait stations for termites, bait and exclusion for mice, treatment of the harbourages for roaches. The crawl space is checked again on the follow-up visits, because the moisture returns after every heavy rain.
Keeping the crawl space dry
Keep the gutters clear and the downspouts extended away from the wall. Keep the grading falling away from the foundation. Do not store cardboard or scrap timber in the crawl space. Keep the vents clear and covered. And have the crawl space inspected once a year, in spring — the visit is short, and the record it builds up over the years is what catches a colony before it becomes damage.
It is damp, dark and full of wood, and nobody looks in it. Termites, carpenter ants, mice and roaches all use it — and the moisture there is what draws them in.
Once a year, in spring. The inspection takes photographs and moisture readings, and the record builds up year by year.
About 41 inches of rain a year, grading that falls toward the wall, gutters that dump water at the foundation, and vents that let the damp in.
