TECHNOLOGY FOCUS - PHARMACEUTICALS - Preferred Method: The method involves administering a composition comprising: a) a composition A which is a hexadecanoic acid and diethylenediamine with an olfactory attractive index of 0.3-0.4; and b) a composition B which is a combination of butylated hydroxy toluene (BHT) and isopropanol with an olfactory attractive index greater than 0.47, to a target area, where composition A masks humans from the mosquitoes, and composition B attracts contact of the mosquitoes with the target area; or involves administering a composition comprising: a) a composition A which is a thiomorpholine, 4-methyl and diethylenediamine with an olfactory attractive index of 0.3-0.4; and b) a composition B which is a combination of BHT and isopropanol with an olfactory attractive index greater than 0.47, to a target area, where composition A masks humans from the mosquitoes, and composition B attracts contact of the mosquitoes with the target area. The method further involves: a) vaporizing the composition in the target area thus attracting the mosquitoes into the target area, and b) generating carbon dioxide (CO2) in the target area thus killing the attracted mosquitoes by asphyxiation. The vaporizing is at 37 degrees C. The temperature is maintained with heating elements. The heating elements are graphite rods. The CO2 is generated by exciting TiO2 with UV LEDs. Preferred Composition: The composition comprises: hexadecanoic acid ( approximately 0.08-0.15 wt./wt.%); diethylenediamine ( approximately 0.26-0.73 wt./wt.%); BHT ( approximately 1 wt./wt.%); isopropanol ( approximately 1 wt./wt.%); and liquid Paraffin or ionized water ( approximately 96.12 wt./wt.%); or the composition comprises hexadecanoic acid ( approximately 0.08-0.15 wt./wt.%); thiomorpholine, 4-methyl ( approximately 0.26-0.73 wt./wt.%); BHT ( approximately 1 wt./wt.%); isopropanol ( approximately 1 wt./wt.%); and liquid paraffin or ionized water ( approximately 95.40 wt./wt.%). The composition further comprises perfume which is present in an amount of approximately 1 wt./wt.%. The composition is a combination of BHT and isopropanol. ACTIVITY - Insecticide.
