I have noticed that the fireant problem has seemed to decline as well. I remember when, if you had one fireant hill in your yard, you probably had at least half a dozen or more, but there only a couple of small mounds on my 1 acre lot now, and I haven't bothered to treat them. Lately I have had an infestation of little black ants that have tried to take over my house since the A/C went out a few weeks ago. They found my sugar stash in the bottom cabinet, so I bought some liquid ant bait and that has reduced their population, but I'm almost out of it. I have heard that you can make your own ant bait/poison with sugar water and borax, so I bought a large box of borax and will try it. I just got my A/C fixed today (thank goodness!) so I'm hoping the cooler temperature and reduced humidity will not be so attractive to them as well, but right now, I'd vote for ants being my greater pest.
However, my daughter would likely disagree with me, because mosquitoes will be biting her incessantly when I don't even notice any. She says that they are more attracted to people with her blood type (O neg), but I don't know. I do notice that I will get bitten occasionally when I'm out at night by myself, but I think they all go to her if she's nearby, which works for me!
(In my defense, she's 18, constantly argumentative and thinks she knows everything, and not a child anymore, so I'm not as protective of her as I once was.)
