Difference Between Dampwood Termites And Formosan Subterranean Termites

Updated on: July 14, 2022

Termites might look and act the same for every property owner, but these pests actually have various species. Dampwood termites and Formosan termites are two of the most common species infesting properties - each has different behavior, appearance, and other qualities. Telling them apart can make a huge difference between implementing haphazard termite treatment procedures and having a strategic pest control plan for the type of colony you have.

So what are the differences between dampwood termites and Formosan subterranean termites? Dampwood termites are brown to reddish in color that are about 9 to 15 mm long with big heads and pincers, while Formosan termites are brownish-yellow pests about 12 to 15 mm long with elongated heads. Dampwood termites are also attracted to damp or decaying wood and don’t nest in soil, unlike Formosan termites that invade the house through wood-to-ground contact.

Comparing Dampwood Termites and Formosan Subterranean Termites

Dampwood termites and Formosan subterranean termites might both be wood-destroying insects, but they have stark differences that will greatly help property owners identify and handle a termite infestation. They differ by appearance, where they're found, nesting habits, destruction, and signs of damage.

Appearance

A dampwood termite isn't difficult to tell apart from a Formosan subterranean termite. Dampwood termites can be pretty large, with their nymphs about 9 to 15 mm long, reproductive members around 25.4 mm including the wings, and their soldiers around 20 mm. The nymphs are white to cream in color, while the soldiers are reddish-brown. You can easily distinguish them by their large heads and pincers that comprise 1/3 of their bodies.

A Formosan termite has a lighter color than a dampwood termite. A worker in a Formosan termite colony has a white to an off-white color, but they can be easy to mistake for another termite or pest. That's why pest control experts will usually look at the soldier termite or the Formosan termite swarmers to distinguish the colony.

The soldier termite in a Formosan subterranean termite colony has egg-shaped heads -- soldiers of native subterranean termites have rectangular heads. Like dampwood termite colonies, they also have reproductive members -- Formosan termite swarmers have a yellowish-brown color and are about 12 to 15 mm long. If you catch a winged termite or a swarm of these pests, your property might have a Formosan termite infestation.

Where They're Found

Dampwood termites can't live without moisture, so they're usually found in locations with ample dampness. They're pretty common in Western states, like California, Oregon, Idaho, Nevada, Washington, and Montana.

Formosan subterranean termite colonies prefer staying in warmer places. Because of this, they might be common in states like Alabama, Florida, North Carolina, South Carolina, Mississippi, Texas, and other states with similar climates.

Nesting Habits

A dampwood termite colony usually nests in a damp wooden structure instead of the soil. That's why property owners must always ensure their pipes aren't leaky and their gutters are functioning properly -- water from these might come into contact with your structural wood and become damp, breeding a dampwood termite infestation.

Dampwood termites can also work their way up from your foundations to your roof rafters. Unlike other termites, they don't infest structures with contact with soil. They are pretty tricky to spot because, so seeking a pest control professional can help you identify what infests your property.

A Formosan termite colony will invade your property if the ground comes into contact with soil because they live underground. It tends to make its nest out of frass, excrement, soil, wood, and saliva – these are called shelter tubes or mud tubes.

Destruction

Between the two, a Formosan termite colony is more notorious when it comes to destruction or wood consumption, being called "super termite" because of how fast they can cause damage and how large they are in a colony. A dampwood termite infestation can take around 3 to 8 years, with as high as 4,000 members in a mature colony.

Formosan termites, also a type of eastern subterranean termite, can have a large colony involving millions of termites. Because of this, they can cause severe damage to foundational structural wood within at least 6 months.

Signs of Damage

The signs of termite damage done by Formosan and dampwood termites can be similar, but they would still have stark differences. Damage to structural wood done by dampwood termites will appear smooth inside, unlike Formosan termites that create tunnels and galleries. Dampwood termites also don't leave visual signs of termite damage -- they don't make shelter tubes or mud tubes. They also use their excrement as a seal from the outside air.

A Formosan termite colony will create mud tubes from the soil up to the wooden structure of your property. They also build galleries in structural wood, making it easier to spot a Formosan termite infestation than those done by dampwood termites.

How to Get Rid of Termites

Distinguishing the types of termite species, whether it’s a dampwood termite, a Formosan subterranean termite, or even a drywood termite, allows you to have a better idea about what you’re faced with. You’ll have an idea about the best way you can get rid of termites and how to implement termite treatment procedures.

Some ways you can do to get rid of termites, both dampwood and Formosan termites, are:

  • Placing termite baits - termite baits lure termites to consume the insecticides. These termite control products also have a slow-acting effect allowing termites to return to their colony and spread the poison.
  • Applying direct chemicals - direct chemicals are suitable indoors because it eliminates termites upon coming into contact with it, unlike termite baits and non-repellent insecticides. Pour some of the product into corners, crevices, and other areas in your home with suspected termite activity. The product will expand into foam and leave a poisonous residue that lasts for months.
  • Applying termiticide barriers - most termiticide barriers have a slow-acting effect similar to termite baits. Apply this product along the perimeter of your home or near entry points. Termites won't be able to sense and avoid the insecticide. The chemical will cling to their bodies and spread to other termites once they return to their colony, eliminating the entire nest.
  • Placing beneficial nematodes - you can find this in gardening stores -- these are beneficial worms you can mix in with your garden or in the soil. The parasites will look for a host to release bacteria poisonous to termites.
