08 Jul 2024 --- Kao and Riken researchers say the incorporation of low-viscosity polydimethylsiloxane (L-PDMS) in a topical silicone oil repels mosquitoes “significantly” and enhances effectiveness. They warn “mosquito-borne diseases are posing an increasing threat to humans worldwide.” The study in Scientific Reports focused on L-PDMS’ impact on mosquito behavior and its potential to extend the effectiveness of traditional repellents. Researchers found that mixing L-PDMS in repellant improves its adhesive properties, helping it stick to mosquitoes’ legs longer and reducing the number of bites on human skin.
