I wanted to share with everyone the success I've had killing flies.
I noticed yesterday that there were a lot of flies around the yellow toys in the kids sandbox.
I had put a bowl of soapy water out last week to catch flies, and caught about ten.
Seeing that the flies were attracted to yellow, I put a yellow bowl of soapy water outside yesterday. The bowl filled up fast with flies so I dumped and refilled it. In just two hours I must have killed 50 flies!!
The best part of this is that it's safe to have around kids and pets,and it doesn't have a bad smell like those fly bags.
Hope this can be helpful to someone!
