You are very lucky. It seems that the chemical makeup of some people just attract mosquitoes more than others. I am one of those people that mosquitoes adore.
I have lived in Florida for six years. I do not live near a pond or lake (our lake is five blocks away). I have my yard treated on a monthly basis and I have a screened lanai. I do not spend time outside in the evenings. I even mow the yard in the middle of the day, no matter how hot it is, to avoid bugs. They still find me.
Recently, a census worker came to my door. I stepped out on my front porch to talk to her and got bit. This was in the middle of the day. I don't have a lot of shrubs or anything surrounding my porch either.
My daughter is also a mosquito magnet. She went to the Magic Kingdom with a friend a few weeks ago. While waiting at the TTC in the middle of the day, she got bit on her feet three times. We are both the type that swell dramatically when we get a bite. She once had to go on an outing with her school to a park. By the time I picked her up, she had 27 bites. She ended up getting sick to her stomach from them. To make things worse, she is deathly allergic to DEET.
Of course, I also got bit three times this summer by those stupid yellow fly things. My leg swelled up with a knot the size of a baseball.
So, consider yourself lucky if you are one of those people who mosquitoes shun. I wish that were me!
