It forms larger colonies and is more resistant to pesticides than domestic subterranean termites.

It has reached nine southern states: Louisiana, Texas, Mississippi, Alabama, and Florida, with smaller concentrations in Georgia, Tennessee, and the Carolinas. Southern California is beset, as is Hawaii, which has fought it for more than a hundred years.

These warm–weather bugs likely wouldn't survive a winter in forest or field much farther north than the Carolinas. But they can survive for years if introduced via a piece of wood to your warm, moist home—even if it's in Canada.

There are three primary steps you should follow in keeping termites at bay:

1. Be watchful. Make sure you aren't bringing termites into your home in wood or paper

2. Keep moisture out of your structure

3. Use only pressure–treated wood in building or remodeling
