Does intense spraying make mosquitoes more active?

So. Thanks to ZIKA, they have been spraying insecticides more often than in the past in my area. I would assume they are doing the same in other mosquito prone areas.

Lastnight the mosquitoes were worse than I can ever remember. I had to wear insect repellent inside at my job. Everyone was covered in bites,and some refused to work our outside bar.

Has the increase in insecticides made the mosquitoes more active? It seems like they were flying faster and bitting more than ever. And the place I was is usually not even that bad for mosquitoes.

I’ve seen fleas gets more aggressive after an animal takes a Capstar. They seem aggravated by poisons ,and even though they die, they go out bitting.

Are the mosquitoes worse where you are right now?

Or do I just notice them more,now that I’m afraid of contracting the virus?
It wasn’t just me lastnight, it was everyone.
