Chlorfluazuron has proven to be extremely effective for termite baiting becuase:

• It is a benzoylphenyl urea insect growth regulator which inhibits the synthesis of chitin
• Only one gram per kilo of Chlorfluazuron is required to effectively controll termite colonies 
• Its delayed mode of action allows widespread transfer within the colony for maximum secondary kill
• It is effective against all sub-species of subterranean termites with the exception of Mastotermes Darwinius
• Chlorfluazuron is practically non-toxic due to the mammals, birds, fish and earthworms (Tomlin 1997)
• It slowly degrades in water 
• It is strongly absorbed to soil with a Kd of 120-990
• Its half life in soil varies from 6 weeks to a few months
