Subterranean termites live underground and build tunnels; and like other termite species, they feed on products containing cellulose. Subterranean termites swarm in the spring – groups of reproductive termites (called alates) are winged and leave to start new colonies.
Need contact with the soil to survive. They are capable of building tunnels through cracks in concrete. Subterranean termites are by far the most destructive species. With their damage, they can collapse a building entirely. The hard, saw-toothed jaws of termites work like shears and are able to bite off extremely small fragments of wood, one piece at a time.
