Help, my yard is infested with fleas everywhere and they are vicious. Worse this year than ever. We have lots of sand and do not know what to use. I have several flower gardens and am starting a vegetable garden. We have 3 goats, 1 dog and some indoor animals. What can we use on the yard to stop these pesty pests. They are eating us up. I am using borax on the carpets and furniture, I would like to stay as chemical free in the house as possible, out side I would consider nuking them if needed.
