Scientists at the Hebrew University in Jerusalem have created “chemical camouflage” that reduces mosquito bites by up to 80%. In addition, reducing the number of bites also reduces the frequency of egg laying, reaching a 99% reduction. The new repellent is also effective against bites from Aedes Aegypti mosquitoes, which carry dengue fever, according to the study.
Scientists have been studying for years how to reduce the number of mosquito bites, and in general, the use of repellents has proven to be very effective. However, the difference between the studies of Israeli scientists is that the repellent consists of natural compounds contained in flowers, with a long-lasting effect. The study was published in PNA Nexus in April 2023. According to the results, the compound prevents mosquitoes from landing on the skin by 80%, and the duration of the effect can be extended with reproduction reduction techniques to reduce the number of times females lay eggs by 99.4%.

Camouflage to prevent mosquito bites
ABOUT cellulose nanocrystals (CNC) are used in the formulationspresent in plants and flowers. Scientists claim that the organic compound forms a thin film on the user’s skin with a long-lasting effect, and is also easily dispersed in the aquatic environment. Thus, the product can replace traditional chemical compounds and be used as a repellant.
CNC prevents mosquitoes from identifying human skin as attractive to bite by reducing the number of times the insects land on our body. Thus, chemical camouflage is produced with 100% organic and natural product that also reduces environmental impact. The repellent has been tested on Aedes Aegypti mosquitoes where it has proven to be very effective in reducing bites and oviposition. The results are positive and could help people fight insect-borne diseases like malaria and dengue fever, scientists say. We can only hope that research continues and CNC repellent becomes a marketable product to keep people safe.
