Adulticiding is controlling mosquitoes in their adult stage. Adulticides are products that rapidly reduce adult mosquito populations. This can become necessary when larval control measures are insufficient or not feasible. Adulticiding may be initiated when there is evidence of significant populations of mosquitoes in a region or if there is evidence of mosquito borne disease in Lee County . The most common method of adulticiding is ultra-low volume (ULV) spraying. ULV spraying is the process of putting very small amounts of liquid into the air as a fine mist of droplets. These droplets float on the air currents and quickly eliminate mosquitoes that come into contact with them. ULV adulticides are applied when mosquitoes are most active-typically early evening or pre-dawn. Adulticides can be applied from hand-held sprayers, truck-mounted sprayers, helicopters or airplanes.
