I used a borax laundry soap on roaches and got rid of them. It took a while but we have dogs so I didn't want to use any chemicals. I put it in all the cupboards and on top of the cupboard. Neighbors hauled loads of household trash out of their back yard and our house was immediately infested. It was awful. I don't know if it works on ants but if I get any ants I'm certainly going to try it. Now to find something for scorpions. Yuck!
