BethESH, I've been having problems with fruit flies in my kitchen. Apparently, my grocer has not used your method. But it sounded so easy, I ran to the kitchen and got my sugar water set up already. It was hard for me to leave the kitchen, but I think I was looking a little manic.
It's funny: I hadn't started on my water-bag/penny deal because my son had just completed his Coin Collecting merit badge, and for it we had searched high and low for a 2009 penny, but none was to be found. So I knew all of our piles of pennies lacked the required shine. Well, at the used bookstore today, I was going to pay with exact change, and when I spread out my four pennies in my hand, lo and behold, three were sparkly 2009s! My kids were looking at me like I had lost my rocker because I was acting like I found the winning lottery ticket. Nobody joined in with my glee. I can't figure some people out.
Well, the only bags I have are zip-loc right now, so I guess I'll try them. But I'm going to have to wait till the sun is setting to put them up. I don't want to smell myself smelling like cooking bacon!
