Peer-reviewed research shows that Aedes aegypti mosquitoes can habituate to DEET within hours of exposure and that insecticide-resistance mutations modify how mosquitoes respond to repellent compounds, raising concerns for the billions of people who rely on DEET-based products as frontline defense against malaria, dengue, and Zika. While the evidence is real, scientists caution that laboratory findings do not yet demonstrate large-scale field failure of properly applied repellents — and a new generation of receptor-targeted compounds is in early development, though years from commercial availability.
