I'm wondering if mosquito coils will help? I found some in my camping kit. I'm not sure I will find any in the stores right now, since it is "off" season, but I will be looking. I'm planning on bringing the little coil holder and will have it smoking near our chairs. I might look ridiculous, I've loaded up on insect repellent of different varieties and plan on plastering it on frequently. Maybe some citronella candles toooooo? laugh out loud-anything is worth a try.
