I prefer Mospel(120-125 rs for 45ml bottle) and Mortein Spray(250-280 per spray can).
Most effective in my opinion. Those sprayers carrying them machines on their back, bet it ain't even laboratory tested for dangerous chemicals and is probably homemade using god knows what.
Mortein Coil is great too, just be cautious to not leave it naked under fan, the ashed spread everywhere! Try to light it up in a spare steel plate, and leave it under the bed/table or any other place where the air of the fan can't reach it! Good luck against these mosquitoes!
