I posted this in the other forum but got no replies...I also tried to read up about it from former post but everything I could find was about chickens. We have to spray every year around our house for ants, they are really bad. I have tried natural products but haven't found any that works very good so far. We usually spray a few times a year around our house with Hotshot in the gallon sprayer. The duck pen is getting run over by them please help with a duck safe product.
