Natural insect repellantFeatured science projectScience project video


The hypothesis that  Deet mosquito repellant is  more effective  than  lemon grass oil, is proven to be true.

The instructions on the label of the insect repellant must be carefully read and followed before use. Caution must be taken especially when  children or pregnant women  are exposed to the spray. Only a small amount of the repellant should be used on children because they are at risk of reacting adversely.

Also consider

The science fair project can be repeated by comparing the effectiveness of other natural mosquito repellants like Neem oil.

Try to modify the science project to compare the effectiveness of eucalyptus oil in keeping  flies away from food.
