Another Ant-Baiting Episode

It looks like ants have taken up residency in one of my Jerusalem artichoke pots.  I noticed the ant trail, and also saw that when I watered the pot they'd come surging out of the soil.  I tried placing bait along their trail into the pot, but it was an old tube of Optigard and it had a fair amount of leakiness to it--there was some gel but also some liquid.  The ants didn't mind and rapidly formed up to get whatever they could.

There's still some activity in the pot, so whatever I did didn't take them all out.  I may try again later.
