bbq: every time i bbq there are masses of flies that come from all over. i mean more then 100 flies. as soon as they sense the food they come flying in masses. i was wondering if there was some sort of repellent to keep them away!|||We use Yard Guard. It is a spray that you use to spray the area you using. Also those netted tent/gazeebo things are handy and you can get good deals on them. (if you are eating outside)|||Hang bags of water around.|||Yeap! Maybe you could put some Off! Lotion into your bbq. =) Kidding! Buy some fly papers and put them beside your bbq. They would stick to the paper until they die. ;) Try it. It really works.
