What type of termites live in the soil around houses?
The type of termite can affect the length. Subterranean termites and drywood termites are the most common. Subterranean termites live in the soil around houses and build tunnel networks to access their food—the wood that your house is made of. Drywood termites, on the other hand, tunnel within your wood and eat right through it.

When was chlordane first sold?
Chlordane appears as a white or off-white crystals when synthesized, but it was more commonly sold in various formulations as oil solutions, emulsions, sprays, dusts, and powders. These products were sold in the United States from 1948 to 1988.
When was chlordane developed?
Technical chlordane development was by chance at Velsicol Chemical Corporation by Julius Hyman in 1948, during a search for possible uses of a by-product of synthetic rubber manufacturing. By chlorinating this by-product, persistent and potent insecticides were easily and cheaply produced. The chlorine atoms, 7 in the case of heptachlor, 8 in chlordane, and 9 in the case of nonachlor, surround and stabilize the cyclodiene ring and thus these compounds are referred to as cyclodienes. Other members of the cyclodiene family of organochlorine insecticides are aldrin and its epoxide, dieldrin, as well as endrin, which is a stereoisomer of dieldrin. Cyclodiene derives its name from hexachlorocyclopentadiene, a precursor in its production.

How long does old strong stuff last?
Many homeowners think that when they had their homes treated with “Old strong stuff” (Organochlorines) it would last for 35 to 40 years.

Then Organochlorine chemicals were withdrawn from the schedule of termiticide in 1995 due to health reasons. This means that all houses treated with Organochlorines (Heptachlor, DDT and Chlordane) have now expired.
