well everyone iv never herd about this being done, an old farmer we visit every year to kill the rats ent been in touch so i went to see him this morning to see if we could have a morning over christmas rating, he said there wasnt any there! i asked why and he told me an old boy had come to see him and told him if he catches a live one and sprayed it white then let it go within a few weeks his place would be free from rats, he said he did exactly that, and there is no account of a rat on his place.
this to me is realy very new,
Does anyone no about this if so please let me no?
