Significance of the Study
One of the greatest risks to our environment and our health comes from the chemical pesticides. In spite of the threats, the government continues its approval of the use of toxic chemicals in making pesticides. Moreover science is constantly developing variations of poisons.

That’s why the purpose of this study is to develop less expensive and environmental friendly alternative for killing pests.
