A type of method that is used to estimate population is called Mark-Release-Recapture or the Lincoln Peterson Method. The basics of this particular method are you capture a certain number of what you are trying to find the population of, then you mark them and let them go, then you go back and capture more and see how many are marked and how many are not.
You use this formula N= (m)(s)
t
N= The Estimated Population size.
m= number of termites (in this case) marked in the first capture.
s= number of termites captured in each round.
t= number of marked termites in the recapture.
