Malaria and other mosquito-borne diseases remain a serious threat in many poor communities around the globe; fogging entire towns and neighborhoods used to be the normal practice to prevent this. That method is not only expensive and outdated; it is also impractical because it is off-target and widespread spraying makes most mosquitoes more resistant to the pesticide. Insects, wildlife and other domestic animals also remain at risk from exposure to pesticides due to fogging.

More contemporary and targeted pesticide application methods have been developed throughout the years. One such method is using pyrethrin-soaked bed nets to protect sleeping children. Although proven effective, prohibitive costs still make it inaccessible to low-income households.

Another experiment with promising results is the use of carbamate-impregnated polypropylene. This “sheeting” material is hung against the interior wall surface where mosquitoes prefer to alight. Using this method along with the bed nets has been proven effective especially against more pyrethroid-resistant mosquito breeds. Read the full article here
