DEET is a chemical commonly used in mosquito repellents, however, this does not make it the most effective or the safest form of repellent. In this experiment two formulas were tested; the first was a repellent containing DEET, while the second was a new formula containing formic acid. Formic acid, or  methanoic acid, is a chemical compound found in nature and created by certain breeds of ants. If formic acid is a better repellent to mosquitoes than DEET, then the cream with formic acid will repel mosquitoes better than the cream with DEET. To test this hypothesis, the researcher had to create a new solution which included formic acid. Once the repellents were ready, the researcher had to obtain mosquitoes and create a testing space. The repellents were applied to skin samples, and then put into the mosquito enclosures to begin testing. Unfortunately, nothing can be concluded from this experiment since there was no clear data collected during testing. The skin with no repellent was not bitten and the skin with formic acid was also untouched. With the mosquito population growing and introducing more diseases, this experiment is both relevant to today's problems and helpful in trying to keep these problems at bay.
