Transfluthrin can be used in the indoor environment against flies, mosquitoes, moths and cockroaches.

[1][3] Transfluthrin, if used contrary to product instructions, may cause symptoms of poisoning including nervousness, anxiety, tremor, convulsions, skin allergies, sneezing, running nose and irritation.

[4] In experiments, transfluthrin was shown to kill 85 percent of mosquitos within one hour of exposure at concentrations below 0.3 μg/m3 (which was the detection limit) in air.

[5] (The data suggests that transfluthrin is effective at these concentrations within much less than an hour of exposure.)

Various household transfluthrin products such as vaporizers and mosquito coils may result in concentrations of 15 μg/m3 to 40 μg/m3.
