I have 13 nests in a 40 by 80 feet lawn and as much as I llike ants it is impossible to let my rabbits graze. Yesterday I found the rabbits flying around their enclosure, not exercising, trying to rid themselves of the black ants crawling all over them! They had to be washed and put back in their hutch which is now on legs and surrounded by washing up liquid as the ants hate this and won't travel over it. It has become impossible to sit in the garden. within minutes the little demons are all over our legs. I agree with leaving nature alone as much as possible but our garden has become off limits to us and our pets and I need a solution that will do as little harm as possible to rabbits, dogs and if possible even the ants.
