What ingredients is needed for bed bug spray?

To make a bed bug spray, you typically need ingredients like water, rubbing alcohol (isopropyl alcohol), and essential oils such as tea tree oil or lavender oil, which are known for their insect-repelling properties. A common homemade mixture involves combining equal parts of water and rubbing alcohol, along with a few drops of essential oil. Always test the spray on a small area first to avoid damage to fabrics or surfaces.
