For many low-income farmers, commercial pesticides are too costly to use. Seemingly, the next best option for many is to turn to homemade botanical insecticides using local sources. But how reliable are these resources, and are they safe to recommend?

This paper specifically focuses on previous studies that tested homemade preparations under “realistic local field or storage conditions”, as there has been no previous in-depth review on this particular topic.
