DEET Places First, Eucalyptus Takes Second
One study compared widely available chemical and natural insect repellents containing one of the following ingredients:

Of all the products, the DEET-based ones guarded adults from mosquito bites the longest. Protection time increased with DEET concentrations. For example, DEET 4.75 percent lasted about 1.5 hours. DEET 23.8 percent gave around five hours of protection.
