Keep Bugs Away From Your Plants

Another surprising use for aluminum foil actually involves using it to repel insects. This is especially useful if you want to keep pests, like aphids, away from your garden. An old study conducted by researchers found that plants with aluminum foil were 25% less affected by pests, according to the Washington Post. The foil is thought to disrupt insects' ability to identify plants that they prefer. Foil can also be used as mulch.

In order to use your foil this way, just cut a few strips and lay them down at the base of your plants. The more you use the better, but as long as around 50% of your garden's surface area is covered, your plants should be protected.
