Icaridin has been reported to be as effective as DEET at a 20% concentration without the irritation associated with DEET. [ 12 ] [ 13 ] According to the WHO, icaridin “demonstrates excellent repellent properties comparable to, and often superior to, those of the standard DEET.”
DEET is effective against a variety of invertebrates, including ticks, flies, mosquitos, and some parasitic worms. [3]A 2018 systematic review found no consistent performance difference between DEET and icaridin in field studies and concluded that they are equally preferred mosquito repellents, noting that 50% DEET offers longer protection but is not available in some countries.
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.
Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents. [1] [2]For protection against ticks and mosquito bites, the U.S. Centers for Disease Control (CDC) recommends DEET, icaridin (picaridin, KBR 3023), oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), IR3535 and 2-undecanone with the caveat that higher percentages of the active ingredient ...
The active ingredient in Aerogard is N, N-diethyl-meta-toluamide (DEET). [2] Recent low-odour formulas use Picaridin (See Icaridin) History
Placing screens on windows and doors is a simple and effective means of reducing the number of mosquitoes indoors. Anticipating mosquito contact and using a topical mosquito repellant with icaridin or DEET is also recommended. Draining or covering water receptacles, both indoor and outdoors, is also a simple but effective prevention method.
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 ...
Picaridin, available at 7% and 15% concentrations, needs more frequent application. DEET formulations as high as 30% are recommended for children over two months of age. [ 65 ] The CDC also recommends the use of: IR3535, oil of lemon eucalyptus, para-menthane-diol, or 2-undecanone. [ 66 ]
