The efficacy of repellents is of high health importance. Efficacy is influenced by test persons used, insect species, age of insect, temperature, humidity as well as various other factors. To generate comparable results, test Guidelines were developed for the evaluation of repellents by authorities and WHO.
Different Guidelines are listed in the table below.
