Termites are social insects, living together in colonies. The colonies of subterranean termites can contain up to several million termites. They are divided into castes which determine their activities. Termites in the worker caste dig tunnels and ensure food supply. Soldiers prevent intruders from harming the colony, while reproductive termites perpetuate the species by ‘swarming’ annually to start a new colony. Termites are active 24/7, 365 days a year.
