Specifically, dried-fish is a popular dish of Bangladeshi people, so it is needed to save this food item from the rats. Additionally, there are many renowned pigeon houses in Bangladesh. Each year many pigeon breeders lose significant number of pigeons due to rat-infested incidents. To use poison for killing rats is not scientifically sound method. Only physical and biological method can be the best solution. Rats have high value in nature for ecological balance because many animals eat rats as their food.
