Effect of Bird's Eye chili(i.e. capsicum frutescen) on Gryllus assimilis (the common black cricket)Featured science projectScience project video


The hypothesis that Bird's Eye chili extract will repel and kill crickets is proven to be correct.

Crickets are insects that belong to the same family as grasshoppers. They make a loud, high pitched chirping noise that is comforting for some but can be irritating to others. One of the safest methods to repel crickets is to use pepper spray. However, care must be taken to avoid contact with the eyes or plants. Pepper can cause pain and irritation if it comes into contact with the eyes .

Also consider

What would happen if the experiment were to be repeated using different type of peppers like capsicum, red chilies or green chilies?

The experiment can also be done using different types of insects like the grasshopper or praying mantis.
