Most termites are not red. The vast majority of termites you’d encounter are white, cream, pale brown, or dark brown, depending on the species and their role within the colony. If you’ve spotted a small reddish insect near wood damage, there’s a good chance you’re looking at a carpenter ant rather than a termite.
That said, some termite species do have reddish-brown or dark brown coloring, particularly the winged adults that swarm during mating season. Understanding which termites can look reddish, and what’s more likely to be a lookalike, will help you figure out exactly what you’re dealing with.
Why Most Termites Are White or Pale
The termites doing the actual wood damage in your home are workers, and workers are completely white, without any pigmentation at all. They’re also blind. Because they spend their entire lives inside the colony, hidden in wood or underground tunnels, they never need the protection that pigmentation provides against sunlight and drying out. If you crack open a piece of damaged wood and see pale, soft-bodied insects, those are worker termites.
Soldiers are slightly darker, with enlarged brownish or yellowish heads and large jaws, but their bodies still tend to be light-colored. Neither workers nor soldiers would ever be described as red.
Which Termites Can Look Reddish-Brown
The only termites with real pigmentation are the winged reproductives, often called swarmers or alates. These are the adults that leave the colony to mate and start new colonies. Because they’re exposed to open air and sunlight, they develop darker coloring and functional eyes.
Depending on the species, swarmers range from yellowish-brown to very dark brown. Pacific dampwood termites, common in the Pacific Northwest, are caramel-colored to dark brown, with winged adults reaching about one inch long. Formosan subterranean termites produce yellowish-brown swarmers that are roughly half an inch to just over half an inch in length, with transparent, hair-covered wings. Eastern subterranean termite swarmers tend toward dark brown or black. Some of these darker shades can appear reddish-brown in certain lighting, but a truly bright red termite isn’t something you’ll find in the United States.
It’s Probably a Carpenter Ant
The most common reason people search for “red termites” is that they’ve found a reddish or reddish-black insect near damaged wood and assumed it was a termite. Carpenter ants are a much more likely match. Many carpenter ant species have distinctly reddish or reddish-brown bodies, sometimes with a darker head and abdomen. They also damage wood, which adds to the confusion.
Telling them apart is straightforward once you know what to look for:
- Waist shape: Carpenter ants have a narrow, pinched waist. Termites have a broad, thick waist with no visible pinch.
- Antennae: Ant antennae are bent or elbowed. Termite antennae are straight, like a string of tiny beads.
- Wings (on swarmers): Carpenter ant swarmers have a front pair of wings noticeably longer than the back pair. Termite swarmers have two pairs of wings that are equal in length.
If the insect you found is reddish with a clearly segmented, pinched waist and elbowed antennae, it’s almost certainly a carpenter ant.
Signs You’re Dealing With Termites
Color alone isn’t the best way to identify a termite problem. The physical evidence they leave behind is far more reliable. Subterranean termites build mud shelter tubes, pencil-width tunnels made of soil and saliva, that run up foundation walls, support piers, or plumbing under the house. These tubes protect them from open air as they travel between the ground and your home’s wood. You might also notice BB-sized spots of dried mud on interior walls or ceilings. These “pinholes” form when termites accidentally break through to the surface and quickly patch the opening.
Drywood termites leave a different calling card: small piles of uniform, six-sided fecal pellets on floors or countertops beneath infested wood. They push these dry pellets out through “kick-out holes” in the wood’s surface, creating telltale accumulations that look a bit like coarse sawdust or sand.
Swarmers themselves are a strong signal. If you see winged insects emerging from walls, ceilings, or floors inside your home, or find piles of shed wings on windowsills, a colony is already established in or very near the structure. A few swarmers near an exterior light at night are less alarming and may come from a colony in the yard, but large numbers indoors point to an active infestation.
What the Color Tells You
If you’ve found a pale, white insect in damaged wood, you’re looking at a termite worker. If you’ve found a brownish or dark-winged insect with a thick waist and straight antennae, it’s likely a termite swarmer. And if you’ve found something distinctly red with a pinched waist, you’re almost certainly looking at a carpenter ant. Both carpenter ants and termites can cause structural damage, so either way the discovery is worth acting on, but knowing which pest you have determines what kind of treatment is needed.
