Which poison do you normally use / recommend in your gardens? We have had discussions with the leading pest control agencies in our country and every poison they recommend gets turned down on "environmental" grounds. Meanwhile the problem is just exacerbating. I am not sure whether this is, technically, a gardening question, but would greatly appreciate your suggestions. Rat traps would, of course, be used. I don't think anyone here does an ultrasound method, so that just leaves us with poison used in a very controlled manner under the supervision and control of a responsible company/agency.
What Is a Non-Toxic Rat Poison for the Garden?

I am not an expert, but I have heard that mixing equal parts of flour, sugar and either baking soda or boric acid (Borax laundry detergent) is an organic, environmentally friendly and effective rat killer. Place it in areas that the rats go and they will eat it. The baking soda one is supposedly also safe for domestic animals as it kills the rats by swelling their stomach, and domestic animals like cats and dogs are able to relieve the swelling by belching and, therefore, are not hurt by the poison.
