They still spray
Just flew from Dubai to Ahmedabad, India (Sept 27, 2012) - the fumigation process took place with the plane full of passengers, doors locked and we were pushing back from the gate. We were instructed to close our eyes and that was it. I inquired with the crew as to what they were spraying for, the answer was "small bugs, like lice" wow! The gal also stated that they do the same procedure when flying from Dubai to Australia.
