Subterranean Termites

Subterranean Termite Appearance and Size Facts

Subterranean termites are commonly found in Florida, and nearly every other U.S. state except Alaska. They’re known as one of the most destructive types of termites, causing billions of dollars’ worth of damage nationwide each year.

If you suspect you’re dealing with subterranean termites, look for these traits:

  • Varying in color, either cream, yellow, or dark brown
  • Anywhere from 0.125 inches to 0.3 inches long, as small as some ants
  • Straight antennae, “soldier” termites have enlarged heads
  • Known to swarm, typically around spring or summer

Identifying Subterranean Termites From Other Termites 

The simplest way to distinguish between different types of termites is to observe their nesting behavior. While drywood termites nest in the wood they feed on, subterranean termites nest underground, building mud tunnels to travel above ground. Drywood termites are also typically larger than their subterranean relatives, up to one inch in length.

Types of Subterranean Termites

Behavior and Habitat of Subterranean Termites

Like all termites, subterranean termites feed on cellulose, a substance found in wood. Since subterranean termites live underground, it’s rare to see them above ground, except for on the occasion that they swarm, which typically occurs in the spring or summer. You’ll usually see termite swarms when conditions are moist, such as after a rainstorm. Termites gravitate toward light, so you may see them next to light fixtures or windows. 

Signs of Infestation of Subterranean Termites

Some signs of a subterranean termite infestation include:

  • Swarms in the spring or summer
  • Termite tubes near your foundation or wooden structures, which may look like caked mud from a distance
  • These tubes are commonly made of mud and look like brown lines
  • Piles of termite wings
  • Sagging or buckling of hardwood flooring
  • Wood damage beneath wallpaper
  • Hollow-sounding walls

Tips for Prevention of Subterranean Termites

Preventing termites is quite difficult, as they find their way into as many as one in five American homes. Warm, humid climates, like those in Florida and other southern states, can contribute to termite infestations. However, you can still take a few steps to make your home unattractive to termites, such as:

  • Keep wooden compartments of your home 12 inches above the soil.
  • Keep foundation areas well ventilated and dry.
  • Avoid placing wood near your foundation.
  • Store all chopped firewood at least 20 feet away from your home.
  • Ensure all plants are at least one foot from your home’s walls.
  • Check wooden fencing for rot and treat the wood to prevent infestations.
  • Avoid all wood to ground contact such as decks and fences
  • Avoid standing water near your foundation or within your crawlspace
  • Ensure any siding or stucco terminates above the soil line
  • Resolve any leaks such as water intrusion from sinks, plumbing, windows, doors, or roofs
