Female mosquitoes can transmit deadly bloodborne diseases and are of particular concern in developing areas including sub-Saharan Africa and Asia. Mosquito repellants like N,N-diethyl-meta-toluamide (DEET) are of limited utility in these regions because they are effective only at short range and are too expensive and unpleasant for daily use. Another control strategy is to burn propane or melt dry ice in designated areas away from people, releasing carbon dioxide to draw mosquitoes off. This strategy is also expensive as well as logistically complicated. Better control strategies are in great demand.
