Using WD-40 as a Bug Repellent.
WD-40 can be used as an insect repellent by creating a barrier between the outside and inside of your home. By using a light coating around doorframes, windows, and any other openings, it deters insects from coming in and seals up your house. It can also be used to manage infestations by spraying it wherever you see the infestation and in any small cracks or holes nearby. This common hardware store product could be the best hack for keeping bugs out of your home this year.
