Intermittent Mosquito Traps

Mosquitoes appear to require overlapping cues — dark visual contrast plus carbon dioxide — to linger on a target, so traps that alternate steady cues with active capture pulses (e.g., on/off CO2 or light with timed suction) could attract then capture more insects while using less energy. Lab experiments from Georgia Tech showed mosquitoes approach independently to the same spot when given combined cues and disperse when cues are not simultaneous. — If validated in field trials, intermittent‑cue trapping could change municipal and consumer vector‑control strategies, lowering costs and improving disease prevention.
