Walmart's Great Value Orange Scent Dishwashing Liquid works really well also. I kept getting ants in the kitchen thru the years, used spray, powder, the ant "food", etc. They kept coming back. When I found them in my dishwasher last time, I did not want to use poisions, so I took the dish liquid and put a few drops where the ants were mingling. They went away! So I took a sponge, put a little on the sponge, added a little water to suds it up and wiped the suds on the counter. They stay away from the kitchen. Am thinking of using it around the foundation. It has a funky smell (does not smell like oranges when wet), doesn't suds much so didn't like it for dishes, but love it for ants! Am going to wash my patio door screen with it and see if it keeps the flys from hanging around. Every time you open the door they come in. Will let you know if it works when fly season gets here. It is a great cleaner for grease also.
