Swarmers: Dark-brown to black in color, about ¼ to ½ inch long with two pairs of wings that are very close to being equal in length.
Workers: No wings, about ¼ inch or less in length and cream colored.
Soldiers: No wings, large mandibles (jaws), termite colony defenders, are creamy-white in color, but their head is often brownish in color.
Appearance of damaged wood: Since subterranean termites build their nests underground, damaged wood usually has an accumulation of soil or mud within the tunnels of the wood they are eating. Since subterranean termites only eat the softwood, damaged wood appears to be layered, the result of the workers not eating the hardwood portion
