Termites in Your Garage — What to Expect

Garage termite infestation commonly affects: the wood frame around the garage door opening (a frequent drywood entry point), the garage sill plate where the framing meets the concrete slab, overhead framing and trusses, any stored wood items (furniture, firewood, lumber), and wood trim and window frames.

The garage sill plate is a particularly important subterranean termite target. The concrete slab creates a temperature differential that draws moisture, and any crack or gap between the slab and the wood framing provides subterranean termite access.

For garage-specific drywood infestations, orange oil spot treatment or localized heat treatment can typically address the affected framing without treating the entire structure. For subterranean activity at the slab perimeter, targeted Termidor injection around the garage slab addresses the colony.

If the garage shares walls with the main living area, a drywood infestation in garage framing can spread into main structure framing. Our inspectors check the garage-to-house wall connection and all shared framing during the inspection.
