How we test

Our test was carried out in an independent laboratory. Price is based on a survey during December 2013.

Tested time is based on the product’s claimed length of effectiveness except where noted.

Our test

Each repellent was tested on 4 volunteers in a laboratory. Each volunteer had a specified amount of repellent spread evenly on one forearm, while their other arm was left untreated as a control. Both arms were placed in a cage containing around 50 hungry mosquitoes for a set number of exposures depending on the product’s claimed length of effectiveness.

At each exposure the lab counted the number of mosquito “landings” and “probing of the skin”. These exposures lasted 1 minute and took place at intervals of 15, 120, 180, 240 and 360 minutes depending on the claims of the repellent (the Bushman repellents claimed to last longer than 6 hours). Each mosquito was removed before biting took place.
