Is there an efficient non toxic / natural fly control?

Here in New Zealand it's summer, and the flies are coming out! Sick of them already and going through too much flyspray... and i don'tthink that is all too good for my littlies...





Any idea's or alternatives?Is there an efficient non toxic / natural fly control?
Ever hear of Venus Flytraps? This is a plant that acutally attracts and EATS flies! No kidding. Look it up if you want, you can probably order them online. They won't attract flies into the house, just the ones that are already there. They also sell Fly Strips, it's a sticky tape that attract the flies to it and they just stick there and die. Hang them in places you don't really see, cause they look gross, but work well. If you get the plant, I would get like 3-5 of them and spread them out around the house.
