It's first time for me to hear about this Mosquito device…I don't know but this is a bit alarming for me..I mean how can you possibly disperse a group of teenagers using some weird sound without damaging their eardrums…also I'm worried of what will happen to our youths if they will be overexposed to this sound…so for me, I'm not in favor of using this device in driving out teenagers. health insurance in Las Vegas
