DEET is often sold and used in spray or lotion in concentrations up to 100%. [10] Consumer Reports found a correlation between DEET concentration and hours of protection against insect bites. 100% DEET was found to offer up to 12 hours of protection while several lower concentration DEET formulations (20–34%) offered 3–6 hours of protection.
A 2013 review concluded that IR3535 is as effective as 20% DEET against Anopheles, citing that some studies reported possibly shorter protection of just 3.8 hours. [ 9 ] [ 6 ] In areas with malaria, the NHS recommends 50% DEET or at least 30% DEET or 20% icaridin instead of IR3535.

A new study has found that DEET, the active ingredient in many mosquito and insect repellents, can be toxic to the reproductive health of worms - warranting further investigation into its ...
A study performed in 2010 showed that picaridin spray and cream at the 20% concentration provided 12 hours of protection against ticks. [2] Unlike DEET , icaridin does not dissolve plastics, synthetics or sealants, [ 3 ] is odorless and non-greasy [ 4 ] and presents a lower risk of toxicity when used with sunscreen, as it may reduce skin ...
DEET was developed by the U.S. Department of Agriculture and was registered for use by the general public in 1957. It is effective against mosquitoes, biting flies, chiggers, fleas and ticks. These insect repellents slowly evaporate into the air, producing an invisible chemical barrier around the areas on the body and clothes where it is ...
