My father entered into a contract with a pest control company to rid his home of rats. This was a one year contract and every few weeks the company came out and put out bait and big traps. Occasionally they would catch one but it got to the point where he could hear them in his house at night after the lights went out, the problem was getting worse not better. I decided to step in and take on the problem first hand. I bought duct tape and hot cayane peper. I duct taped all of his foundation vents closed, and then poured the cayene pepper into a weed blower and went about blowing the entire bottle of pepper under the home. He has not seen or heard a rat in over a year, and has cancelled his contrtact.
