There are over 2,000 different species of termites with over 40 species in the United States alone. Although they have distinct characteristics, most look similar. They typically measure between 1/4 and 1/2 of an inch long and have soft bodies with straight antennae. The queens and kings are larger, capable of reaching over one inch long. Colors range from white to light brown where worker termites often appear lighter, while swarming termites darker. Termites can cause damage to structures including homes.
