Determining the effectiveness of cinnamon oil as a natural insect repellentFeatured science projectScience project video

Conclusion

From the data recorded in the table and plotted on the graph, it can be seen that insects were attracted to the untreated banana, while the layer of cinnamon on the other banana repelled the majority of the insects.

As such, the experimental data collected supports the hypothesis that cinnamon oil is an effective natural insect repellant against insects such as ants, cockroaches, mosquitoes and flies.

Natural pesticides use extracts from herbs, fruits and vegetables to keep our homes free of insects and pests. Although natural pesticides are only effective for a shorter period of time and may be more expensive than conventional chemical pesticides, natural pesticides are safer to use and are more environment friendly. As children are especially vulnerable to the fumes released from chemical pesticides, the use of natural pesticides is recommended in homes.
 

Also consider

What would happen if this science fair project were to be repeated using different type of natural insecticides such as clover or lime juice?

The experiment can also be done using different types of natural substance like vinegar or Borax salt.

Does varying quantity of the natural insecticide used make a difference to your results?
