Summary
Sri Lanka’s Health Entomology Officers’ Association said fogging should not be treated as a standalone dengue-control tool, warning it is used only when scientifically justified and absolutely necessary.
Fogging kills only adult mosquitoes, the group said, leaving eggs, larvae and pupae untouched and limiting its impact on transmission.
More than Rs. 20,000 per round, the practice also kills beneficial insects such as bees and dragonflies, while repeated insecticide use can drive resistance and reduce long-term control effectiveness.
Sri Lanka has already replaced malaria-control chemicals including DDT, Malathion, Solfac and Icon because resistance emerged, the association said.
The warning comes as dengue pressure remains high, with 52,068 cases and 31 deaths reported nationwide so far this year.
If fogging is just 'mosquito theatre,' what proven strategies will Sri Lanka actually use to stop its deadly dengue outbreak?
With fogging failing, why hasn't Sri Lanka implemented advanced solutions like Wolbachia bacteria to permanently control its recurring dengue epidemics?
