I have 'hit' the ants with another round of how I kill them.
Small jar with lid. 1/4 sugar, 1/4 borax, almost fill with water. THIS time, I added the rind of one lemon, zested into the jar. Shake well. I them pour in another jar lid and place by the ant holes. Pretty soon...no ants. Hopefully, now I will be able to get some beans.
