I was going to post this in the pests/predators forum, but I find that its mostly geared for chickens. I think having geese requires using something different than traditional pesticides given the fact that geese eat the vegetation on/ near the area.
Obviously I can't get rid of all the (red) ants in my backyard, but I want to get rid of the ones that are near the areas where my geese are most. I hate seeing when they pick up their foot & scratch it with their bills because I know they just got bitten by one. The ants have gotten real bold too, there are 2 little mounds right next to one of my geese' pools!
I tried using Sevin dust "5%" by pouring a little right on the mound/nest, which caused the ants to run around like crazy... I thought it was working (especially since I read Sevin kills on contact), but the next day, I saw that they just opened another entrance to the mound right next to where the dust was. And the mound was just as active with ants as before
I should also note that I put a little wire barrier around the mound after I sprinkled it with sevin dust to keep my geese from getting too close to any grass in that spot.

Kind of like these ^
What can I use to kill these ants? And how long should I keep my geese away from that particular area?
