h) Wind can be definitely being a factor spreading the insecticide due to its distinctive characteristics in transportation. On the whole, Malaysia’s mean annual wind speed is 1.8m/s and is able to carry particles or water sediments over great distances depending on mass or surface area of the particle. In the case of the mosquito buster, it emits insecticides over an approximate 5000 square feet area due to two locations of mosquito busters in UNIPARK. With the help of the wind, the insecticides are taken across further distances because water particles have higher density and viscosity.
