Products claiming to reduce mosquito populations with salt-water solutions are ineffective, according to a new study. In a series of lab tests using nine mosquito species, a team of expert mosquito researchers found no evidence that adult mosquitoes are killed by salt ingested at concentrations used in several popular mosquito-control products. The findings are reported in the Journal of Medical Entomology.
A derivative of volcanic rock called perlite shows effectiveness as a mechanical insecticide against Anopheles gambiae mosquitoes. The substance is believed to act by causing dehydration in the mosquitoes.
