Bala, I wasn't joke in my mail !
You may try a slow modulation in 20...40KHz range and experiment.
The problem is that any living creature ( including mosquitoes ) are
different. I'm sure about this because I have experiment a while ago
an ultrasonic dog chaser. The results was incredible, some dogs becomes
crazy, others only go away and others licks my hand and the device too !

Be sure that irish mosquitos which are greater dancer need different
frequency than yours ! [ this was a joke, please laugh... ]

best, Vasile
