As a mother of a crew of boys, it's quite often I'll walk into one of the rooms and find something random like this. A sheet of baking paper splattered with Maple syrup straight from Canada. At $10 per bottle, you would understand my gasp at viewing what I quickly found out was a, "fly trapping station". Of course, it is.
You'll notice the family house flyer below promises $1 per fly caught. I'm sure the station will eventually work and yield profits. It's day 2. Not a single one caught yet.
