Eastern subterranean termites are the most destructive pest in Delaware, and they work quietly inside walls, sills and floor joists for years before anything shows. We inspect the structure, identify active galleries and mud tubes, treat the soil barrier and set up monitoring so the colony can't quietly re-enter.
Signs you need termite control
- Mud tubes running up foundation walls, piers or crawlspace framing
- Swarmers or discarded wings near windows in March through June
- Floors that feel spongy, or trim that sounds hollow when tapped
- Blistered or bubbled paint that looks like water damage
- Sagging door frames and windows that suddenly stick
How we treat it
Full structural inspection
Foundation, crawlspace, sill plate, garage slab, deck posts and any wood-to-soil contact, documented in writing.
Liquid soil barrier or bait
A continuous treated zone around the structure, or in-ground bait stations where excavation isn't practical.
Annual monitoring
Yearly re-inspection catches new activity early - the cheapest insurance against structural repairs.
Why this matters in Delaware
Termite pressure in Delaware is rated moderate-to-heavy statewide. Swarm season runs roughly March through June, and coastal Sussex County's sandy, high-moisture soil keeps colonies active close to slab foundations.
