Yes, 50/50. The sugar attracts them, they eat it and the soda makes them explode...sorta. I used to use it all around the perimeter of my porch and parts of my garden in Colorado. Did a great job and no pesticides. Tyler was living with me then, so I was very conscientious about pesticides...and bugs.
Wow. Couldn't be more simple. I just filed that away for future use. I have my yard treated about every 8 or 9 months to keep away fire ants and apparently it keeps away all sorts of other pests, too.
