Workers are similar looking to ants but are white or creamy colored. Soldiers are orange in color and distinguished by their rectangular shaped heads and large pincher-like mouthparts. Swarmer, the members of the termite colony that are responsible for mating and establishing new colonies, dark brown, winged insects. 

Life cycle of Western subterranean termites 

Gradual metamorphosis
Termites are social insects living in colonies with a caste system including reproductives, workers, and soldiers. Termites exchange pheromones to aid in colony communication and determining caste upon need. Completion of caste roles is essential to the survival of a colony. Winged forms leave an existing colony in a large mass. 3% survive and submerge back into the soil to begin developing a new colony. The queen deposits and cares for eggs. As colonies become established, workers forage for food and bring back and feed colony members through trophallaxis. Soldiers guard opening in the gallery and protect colony members from predators like ants. Secondary Reproductives help to care for eggs and egg production when colony mature. Workers make up most of the colony population.

‟I bought a home, sight unseen (I trusted a VA inspector) in rural Cochise County, AZ.
After moving in I quickly discovered that the home was INFESTED with vermin and BROWN RECLUSE SPIDERS!

NW Exterminating installed ‘Desert Guard’ and that took care of ALL of the vermin, and, after a few treatments of Spider Power-Dusting in my crawl space I am free of dangerous spiders!
