prevention includes condoms, long sleeves, insect repellant, screens on windows, etc.
And then there is this:
well, not DDT per se, but insecticides:
During February–March, an insecticide resistance study of Aedes aegypti mosquitoes was conducted to develop vector control strategies, such as truck-mounted, ultra-low volume spraying and indoor and outdoor residual spraying. Mosquitoes from across Puerto Rico were tested using the CDC bottle bioassay to determine insecticide susceptibility, particularly against pyrethroids. Results indicated a high degree of geographical variation with respect to susceptibility to insecticides, and deltamethrin was identified as the most suitable pyrethroid candidate for use in vector control programs (data not shown). Insecticide susceptibility surveillance is ongoing.
