    This product KILLS rats

    Posted by Lou on Sep 8th 2015

    I have a bird aviary which attracts rats . They cant get in the aviary but still a nuisance and since I live by a large open field in the south as clean as you keep the aviary , you still get rat visitors ,

    I place this in homemade pipe contraptions that only rats/mice can get at and not carry away .

    It has eradicated ALL of them but I make sure that every few months I add a fresh rat bar here and there .

    I find this product to be the best and Old Cobbler Farm is an honest company to buy from with fast shipping .
