I think this suggestion stems from the fact that baking soda is a good cleaning agent. It gives them a nice shine, or so it is claimed.

You can source potassium bicarbonate from Amazon (this is an affiliate link and if you buy using the link I may get a fee, at no extra cost to you). When combined with various oils it has been shown to be effective at controlling some fungal diseases. Potassium is less toxic to plants and is a macronutrient they need. Most scientific testing has focused on potassium bicarbonate instead of sodium carbonate. This is a good example of taking a little bit of science and turning it into a cure-all. I found no government agency that recommends baking soda as an insecticide, while many do suggest neem. Spraying a plant to prevent insect damage won’t work. That is quite dilute but it will make the solution slightly alkaline which could harm insects.Īlthough baking soda may work as an insecticide, it would need to be sprayed right on the insect. One recipe used 1 tablespoon of baking soda in a gallon of water. You don’t have to add baking soda to make them work. It is quite possible that these concoctions kill some insects, but neem and other oils do this all by themselves. When you read the fine print, you notice that DIY baking soda insecticides include some neem oil, or horticultural oil, or even cooking oil.
