Ahh, Spring is here!!

Yes, the seasons first mosquito. The little bastards assailed me today as I BBQ'ed burgers on our deck.
I really enjoy our backyard. I really do. But somewhere, some how the little beggars lurk, waiting to ruin my evenings. They seem to prefer me over Sandy. We will sit outside on a cool summers evening and I will be swarmed and Sandy will get nary a bite. I have given this much thought and the best I can come up with is this: skeeters are drawn to carbon dioxide. Of course we exhale c02 when we breathe, also the fermentation process in beer produces carbon dioxide as a by product, ergo beer and breathing produce higher concentrations of co2. The next time I Que, I am going to attempt not to breathe. I've tried not drinking beer while I bbq, but that is a direct violation of the BBQ Act. I think not breathing will be easier.
I really need to figure out how to handle this problem. Pesticide sprays only work for a few days and are rather pricey. The big skeeter traps aren't as effective as I would like, and too, they cost a butt load of money. Maybe I'm just doomed to dousing myself in a gallon of OFF and wearing a mosquito net while I cook. Certainly there is a better way.
