In the Kansas City area, the type of termites we have are Eastern subterranean termites (Reticulitermes flavipes)
I am often asked how large an average size termite colony is and how can you determine its size?
Experts differ on this question, because subterranean termite colony sizes vary by factors that include species, location and the age of the colony. As a rule of thumb, a desert subterranean termite colony (Heterotermes aureus) might number 80,000; an Eastern subterranean colony (Reticulitermes flavipes) might number 250,000; and a Formosan subterranean colony (Coptotermes formosanus) might number 1 million. Research for the Sentricon® Termite Colony Elimination System, dating back more than 15 years, has focused on the amount of bait required to eliminate a typical colony. For example, the Eastern subterranean termite is the most common species in the United States. Research has shown that 65 grams of Recruit® IV termite bait is sufficient to eliminate a typical Eastern subterranean termite colony. One Recruit HD termite bait device contains 150 grams of bait and is, therefore, sufficient to eliminate more than two Eastern subterranean termite colonies. The important point for a homeowner to know is that the Sentricon System provides proven termite colony elimination and ongoing preventive protection when installed and maintained according to the label.
