Ron from Mesa Arizona writes,
To terminate subterranean termites use; Termidor or Tengard?
Termidor is the number one product on the market for termites today and is the product of choice for subterranean termites. Termidor is completely undetectable by termites and once termites touch it they contact, ingest and spread the termiticide until it eliminates the entire colony and it will last for about 10 years in the soil. Tengard can be detected by termites and they will try to avoid the treated areas and it will only eliminate the termites that come into direct contact with treated areas. Tengard will last for about 5 years in the soil.
