Picaridin vs. DEET: How They Repel Mosquitoes

Picaridin and DEET are the two most frequently used chemicals in mosquito repellents. So which of the two should you trust to keep mosquitoes away? Here are the pros and cons of each: 

1. DEET has been in use for many years—it was developed in the 1940s by the U.S. Army. It has been judged harshly for showing the potential to harm people, but it was eventually approved by the EPA after studies showed that it poses no health concerns. Concentrations including 10-30% DEET can give up to 12 hours of mosquito protection. It is important to note, though, that DEET can damage synthetic materials and platics. 
2. Picaridin works to repel many kinds of pests, including mosquitoes, flies, and ticks. It has only a slight odor, does no damage to plastics, and is often used in today’s repellents. It does almost as well against mosquitoes as DEET does, but it does the best work against flies. 

Are Picaridin and DEET Repellents Safe?

Your top priority when shopping for a mosquito repellent should be looking for EPA-approved products. Most repellents sold in stores contain up to 20% picaridin or 10-30% DEET. Whichever you choose, make sure to follow the manufacturer’s instructions on the label. Ask your pediatrician about using mosquito repellents on children. If you follow all of the instructions on the label, your chosen repellent will be entirely safe for you and your family.

How to Apply Mosquito Repellents

It is crucial to follow the manufacturer’s instructions for any mosquito repellent that you decide to use. Some repellents need to be reapplied after a certain period of time to ensure that they continue to do their job. It is recommended that you conduct a skin patch test to make sure that you don’t react adversely to the repellent that you choose. When you have questions, turn to a medical professional for help.
