I'm very concerned about food safety, but at the same time, I like to keep windows open when I cook to get in a lot of fresh air.
Unfortunately, this has the bad effect of allowing flies to swarm in. Lately, I've been having to cook with all my windows closed, and this makes the air in the room extremely stuffy and very uncomfortable to work in.
Is there anything I can use to keep flies out of my kitchen when I cook?
