How to Prevent a Rodent Infestation

You open a cupboard and see chewed up bits of paper and little black things the size of large seeds. You detect a sweet, slightly sickening scent. You may even see bits of torn out fur, paper and shredded fabric with a hollow in the center. Your cat stares for hours at a hole in the baseboards. Your dog barks and scratches at the wall. You hear scrabbling and squeaking. By the time these signs appear, you already have a problem, but it can be fixed quickly and easily with a little effort. Read on to learn how to prevent rodent infestation.

Instructions

    • 1

      Look for rodent droppings, torn paper or fluff in corners of drawers or beneath stored mattresses or boxes. Rodent droppings look like tiny raisins or extra large apple seeds. They can be brown or black and often have a sweet sickening scent from being mixed with rodent urine. Rodent droppings are unsightly, smelly and cause disease.

      Clean the house, attic, basement, garage, sheds and any rubbish piles. Be sure to wear rubber gloves and use a respirator in the attic or garage. Remove any stored mattresses, cloth furniture, cardboard boxes, wallpaper sample rolls, pet foods stored in paper or plastic bags and any other item that can be chewed or used as nesting material or food. Bag everything and place bags in a metal or plastic garbage can with a tight fitting lid.

      Seal up any holes with caulk, wood putty or screening. Rats can get inside through a hole the size of a fifty cent piece, and mice can use a hole the size of a nickel. Cap any open sewer lines, gas lines, or water lines coming into the house. Clean all gutters and downspouts regularly to prevent mice and rats from nesting in them. Keeps doors closed and be sure that screens on windows are intact. Fix them if needed, or replace them.

      Use live humane traps, glue traps or snap traps to get all mice and rats in home. Be sure to place traps out of reach of pets and small children. Release trapped rats and mice only after verifying with your local wildlife officer that they are healthy and making sure to release only in an area away from residences or businesses.

      Join a cleaning and organization group online to help motivate you to keep everything tidy. Spend 15 minutes a day cleaning and organizing so that rodents and other pests cannot get anything to eat, drink, or nest. Go through all cupboards and throw away any torn or chewed packages. Store all dry goods that are not in cans, including pet foods, in plastic or metal containers with tight fitting lids. Keep the pantry clean and organized. Discard all newspaper, paper bags, cardboard, foam padding, carpeting or any other item that can be used as nesting material immediately. Two groups that I have found helpful are Flylady and Christmas Organizing.
