Termite Life Cycle

There are more than 2,000 known termite species in the world, with at least 50 species occurring in the U.S. Termites are typically classified into three groups based on the location of the colony – subterranean, drywood and dampwood. A colony is made up of workers, soldiers and swarmers. Workers maintain the colony, construct or repair the nest, and forage for food for the colony. Soldiers are sterile, and their main role is to protect the colony. Neither workers nor soldiers have wings.

Swarmers, also known as reproductives, have two pair of wings, which lie flat over the abdomen when not in use. In the springtime, after the last freeze – usually when temperatures reach about 70 degrees – the young adult male and female swarmers emerge from their nests in large groups. The female termites release ‘mating pheromones,’ much like perfume, to entice male termites. Once the male locates an alluring female, they break off their wings, symbolizing that they are a couple. The new couple then select a nest location, mate, and become king and queen of a new colony. The queen has been known to live for 30 or more years.

Depending on the species, it can take three to four years before a newly founded colony reaches maturity and produce its own swarmers. In the first year, the queen can lay anywhere between zero and 22 eggs. So at the end of the first year, a subterranean colony may contain as many as 75 individuals, whereas drywoods may contain only a dozen. Because of this, it can take many years before a colony is large enough to cause visible damage to the wood they infest.

In colder regions where termites do not typically survive the winter, new colonies can be started in one of two ways; when infested wood is introduced to a new location, or by division. Division typically occurs when a new food source is located and a subcolony is formed to exploit the source. Eventually, this subcolony can then produce the needed reproductives from nymphs (young termites), and completely break off as its own colony.

With the exception of conehead termites, most termite species cannot crawl on the open ground like ants and other pests. Instead, they build mud tubes to travel between their colony and food sources. These mud tubes are another sign homeowners can use to identify the presence of termites near their homes. Homeowners should also be on lookout for cracked or bubbling paint and wood that sounds hollow when tapped. If you do see signs of termites in or near your home, it’s important to work with a professional to treat the infestation before serious damage is done. Termites are not a pest that can be treated with DIY measures.
