A growing body of independent research
material demonstrates the efficacy
of Citrepel®.

Most cage tests have been carried out with
the Anopheles gambiae mosquito. These are
one of the largest mosquitoes and said to be
the more difficult to repel. They are also the
prevalent cause of malaria in the world.

Duration of protection

At 20% Citrepel® (standard grade) gave a repellency
lasting 3-4 hours in cage tests versus Anopheles Gambia. Results of these tests also indicate that Citrepe® shows similar properties to synthetic materials in the ability to elongate the time of repellency by increasing the concentration used. In field trials in Bolivia, Citrepel® outperformed a range of other repellent materials
including DEET.

Bolivian field trial: mosquitoes captured on skin

In the above test, the repellent was applied on the legs.
Two hours later, the legs were exposed and the numbers
of landings (effectively bites) over the next two hour period were counted. The control had an average of 150 landings, 15% DEET had 22.87 landings and samples of Citrepe®
had 4.68 landings. These tests were performed in
north-eastern Bolivia. Full detail on tests and results
are available from Chemian Technology.
