Pre baiting is the best method to identify the active area of rats and has to be pursued before application of any poison For that, plain food has to be placed in different locations during the late evening- one day prior to the actual application of poison. Later, place the bait mixed with poison at the same location from where the rats have consumed the plain food. Rats always travel in the same way and will consume the poison. This method will ease our way to control the population and will benefit us economically and make sure that we target the rats and not harm any domestic pets.
