Removing Rodents Without Killing Your Budget
First, avoid messy spring loaded traps and invest in Mice Cubes. They're a little pricey at $10 to $12 for a pack of four, but they're worth it. Not only are they reusable, but they're cleaner and more convenient than spring traps. On top of the cost of the cubes, you'll just need enough peanut butter on the door to leave a scent, as well as a little bait to attract the mice.
For an even cheaper option, use a toilet paper tube. Put a morsel of food at the end of a tube and balance it at the edge of a countertop or table. Then, place a tall garbage bin underneath it. The mouse will crawl into the tube, and its body weight will cause it to fall into the bin. Make sure your garbage can is tall enough so that the mouse can't get out.
The best method of keeping mice at bay, though, is prevention. Store food in mouse-proof containers, like glass jars or other air-tight canisters, and remember to cover pet food when it's not in use. Using these tips, you'll be sure to rid yourself of rodents without ripping through your budget.
