I would imagine that's why when there are no other outside influences. However, in the "real world" I would imagine what we do plays just as big of a part as well.

It's been my experience anyone who uses scented soap, deodorant, or has on cologne or perfume from even the previous day attract more mosquito. Sun tan lotion scented or un-scented attract them, hair products, as well as good`ol body heat and c02 from our mouth.

I've seen mosquito repellent sunscreen... I just don't like the idea of covering my skin with anything especially chemicals. If I am working in mosquitoville I wear long pants and shirts and spray down with deet on the outerwear.
