Did you know your pantry and bathroom closet may hold the keys to a natural inexpensive DIY pest control spray for your garden?
Baking soda is a pantry staple that can help prevent and slow the spread of fungal infections like powdery mildew, black spot and rust.
For soft body insects like aphids it acts as a gentle repellant.
Castille Soap acts as a surfactant. Oil and water don’t mix well, and plain water easily beads off waxy leaves and insect exoskeletons. Adding soap lowers the water's surface tension, allowing it to coat plant surfaces evenly and bind active ingredients (like neem oil or essential oils) to the foliage.
It Kills Soft-Bodied Insects: Castille soap acts as an effective contact insecticide for soft-bodied pests like aphids, spider mites, mealybugs, and whiteflies. The soap strips the protective, waxy layer from the insect's body, causing them to dry out and die. It can also clog their breathing pores, essentially suffocating them.
I also add a capful of Thieves Household Cleaner as it helps with plant health and contains essential oils that also are effective on pests.
There will always be pests in your garden but to help keep them down your answers can often be found sitting in your pantry. They ingredients don't harm the environment, non-toxic, and best of all so much cheaper!
