They appear to have two body segments, straight antennae, and two pairs of equally long wings. Ants have three body segments with a narrow waist, elbowed antennae and a longer pair of front wings.
Termites invade structures of all ages, old and new.
The queen can produce thousands of larvae, and colonies can number in the millions. Visible signs of infestation by termites and wood destroying insects include mud tubes along foundation walls, blistered or wavy wood, sawdust-looking residue next to beams or studs, and sagging floors. By the time these signs are visible, extensive wood damage may have already occurred, since termites eat the wood from the inside out, and their damage can go undetected for years.
