The exotic conehead termite, Nasutitermes corniger, has been found in Broward County, Florida. This is the only known occurrence of conehead termites in the United States. It is assumed that conehead termites entered the state in wooden packing material from a boat that had traveled through the termite’s native range, the Caribbean and Central and South America, and docked at a marina in Dania Beach.

Conehead Termite Damage

Coneheads can wreak havoc on structures and landscapes, causing extensive damage. They eagerly consume dead wood from live or dead trees, shrubs, grasses, roots, wood in structures and furniture, and cardboard and other paper products.

Conehead Termite Identification 

Unlike all other termites in South Florida, the soldier form of this termite species has a cone-shaped, dark brown head from which it secretes a pine sap-like chemical to ward off predators, including ants, lizards, and termites from another colony. Soldiers are difficult to identify with the naked eye due to their size, but the above-ground tunnels they construct (see below) are easily seen and may signify the presence of this species.

Report Conehead Termites

The Florida Department of Agriculture and Consumer Services (FDACS) is working diligently to prevent this invasive termite from becoming permanently established and spreading further throughout the state. FDACS asks Floridians to be on the lookout for these invasive pests and to report any suspected sightings.

To report a conehead termite infestation, call 1-888-397-1517, email or use the form below.

What to Look For


Coneheads travel to their feeding sites in narrow (usually 1/2 inch wide or less) brown tunnels, or termite highways, on the sides of trees, houses, fences or other surfaces.

In spring, winged termites, called alates or swarmers, leave their nests and fly to a new location to start another colony. This is how the termite infestation spreads. Dark wings distinguish conehead swarmers from other local termite species.

These termites build large, dark brown nests with a hard, bumpy surface. Nests can be on, in or by trees or structures, on open ground, or hidden within vegetation.
