X3 on the fans. I have a bunch of rice fields around me that stay flooded most of the summer-mosquito heaven. Two years ago I had one of my dogs get heartworm while on a monthly preventative, so I sympathize with the bug problem. Anyway I started using two box fans, then I came across a 1/2 hp industrial fan with a sealed motor. Now, I only use it and it works great not only to keep the bugs off, but I think it helps a lot to keep the dogs cool. As a side benefit, I take the cage and fan off the motor in the winter and use the motor to run my duck plucker.
