Removing a wallpaper border requires the same process to remove full walls of wallpaper. Clear the area, spray down the surface with your hot water and vinegar solution or store-bought spray, wait 10 to 15 minutes, then scrape it off with a putty knife. Sometimes, border wallpaper lifts easier than larger sheets, so you can just peel it right off the wall by hand.

As long as the surface you’re putting the tile on is properly prepped, peel-and-stick backsplashes should stay on and last anywhere from 3 to 5 years. The best way to ensure the tile stays on is to sand down and clean the wall before applying your design.

Wallpaper lasts an average of around 15 years, but there is some variance. The type of wallpaper matters, as vinyl wallpaper tends to last the longest—sometimes 20 years or more—while a peel-and-stick wallpaper, which is the easiest to install for DIYers, will usually only last for around five years. Exposure to high humidity, smoke, and UV rays from sunlight can also limit the lifespan of your wallpaper, as can heavy traffic in the installation area.

Because poison ivy and similar plants can cause potentially life-threatening allergic reactions depending on your sensitivity, it's best to hire a professional to remove it. Hiring a local lawn care service or other professional also increases your chances of successful eradication so that you don't have to deal with the issue again several months down the road.
