Our lottie seems to have been built on one enormous ant hill. Our ants are yellow. They seem to love our raised beds with its nice friable soil - they moved in very quickly from the nasty clay below!!

Having said that, last year we had a superb harvest, the ants seem to have made no effect on the health of the plants at all. We sprayed the broad and runner beans with a weak solution of teatree to keep the blackfly numbers down, which was very successful.
