rodents..i hate them
..my shop is bordered by turkey barns on 3 sides and 4.75 acres of waist high grass on the other..yep..rodent factory.
make a mixture of 1/3 flour, 1/3 granulated sugar and 1/3 poly filler.
mix well and leave around in locations where you find droppings.
hard as rock mice/rats will be dead as fried chicken in no time. the poly filler isnt toxic and is set up by the time the rodent expires so if a cat or owl gets it things should be ok. just a little chalky.
