If you are worried about mosquitoes it is time to invest in a mosquito magnet. These really work and will make your life much better in the summer time. If you have a mosquito magnet, it is time to remove the tarps and the unit and fire it up.
Another thing that will help this summer is using awnings for shade. The really cool awnings are retractable awnings because you can use them when you want to and remove them at the flip of a switch.
