Though cockroaches are not big contributors to problems such as house pest control, they are still considered one. The main problem in controlling house pests is pesticide. Pesticides being sold in the market are not only expensive; they contribute to environmental problems like pollution and are hazardous to human health.

In connection to this, the researchers planned to make an effective anti-house pesticide so that, people can get rid of the house pests in our house by making a pesticide from Bitaogseeds and Garlic.
