Pest solution tip! For those of us that love watching birds at our back yard bird feeders, this is good advice. The bird seed can and most often will attract rats and mice, especially in urban areas. Suggestion: replace your bird feeder with a bird bath/fountain type feature. Not only is this a green pest solution, but it still allows for bird activity and is pleasing to the ear.
Rat droppings in a crawl space adjacent to a bird feeder 10 feet away. Rat traps were set and the rats, eliminated. After the rats were eliminated, we cleaned out the crawl space (See picture above). The before picture is below.
