If construction crews are making renovations to a home, they make a point to clean up after themselves when they're done. However, it's not uncommon for a pointy nail or two to go missing in the grass. As these objects can pose a risk to anyone passing through the yard barefoot, it's essential they are identified and collected as soon as possible.

Strong magnets could be a big help. While magnetic fields will not interact with every piece of construction debris left behind, they'll certainly attract magnetic items, such as metal nails and screws.

Finding potentially harmful pieces of magnetic metal following the completion of a home repair project is relatively easy. All you have to do is take a large neodymium magnet, such as one in the shape of a cube, tie a string around it and then drag it around the areas where you know the workers were.

Cover as much ground as possible. Of course, it'll take longer in some yards than others. It may take some time, but you'll have better peace of mind knowing you've done what you can to find any stray metal before it has a chance to injure anybody.
