Understanding the biology and habits of termites is very important. After a termite colony has matured (normally 2 to 4 years), Swarmers are produced (usually January through April, during daylight hours, usually after a rain). Other environmental factors trigger the emergence of Swarmers (heat, light, moisture). 

Both male and female Swarmers fly from the colony and travel varying distances. They are very weak fliers and wind currents usually carry those that travel any distance. Only a small percentage survive to develop colonies, the majority falling prey to birds, toads, insects and other predators. Many also die from dehydration or injury.

Moisture is very important to the subterranean termite, who have very little resistance to dehydration. To survive, they must maintain contact with the soil which is their primary moisture source, or other above-ground moisture sources, such as structures with defective plubmbing or guttering.
