The cheap, Easy Way to Make Your Own Insect Spray

Here’s the deal: bugs are gonna happen. To grow plants is to open yourself up to the possibility that you’re not the only thing that wants to eat them delicious herbs you’re growing. It’s part of it. It’s beautiful. And it also sucks sometimes. 

But it doesn’t have to suck so much. For most bugs out there (looking at you: mites, aphids, whiteflies) the first line of defense is going to be an insecticidal soap. What’s that even mean? An insecticidal soap is a mix of water and dish soap. It’s so easy to make, you’ll never have to buy fancy spray again.


The cool part? It’s organic, cheap, and doesn’t harm your plant in the least. For what it’s worth, it does harm the bug. We’ll get to that. 

How Does It Work?

The solution kills harmful pests such as mites, aphids, and whiteflies. The soap will lock them in, suffocate them, and break down their protective shell.

How Do I Do It Tho?

Here’s what you’ll need:

  • Spray Bottle: Make sure if you are recycling an old bottle that it is fully cleaned out. 
  • Dish Soap: Any dish soap will do as long as there are no additives, fragrances or moisturizer. 
  • Water: That's it! 

Here’s What you’ll Do: 

  1. Get the spray bottle (16oz), fill it with about 5% of dish soap, (0.8oz which is around 2 tablespoons – but you can eye this) and fill the rest with water. 
  2. Shake it up, and spray the plant all over. 
  3. Spray every two to three days until they're gone. 

Common Question: Does the soap have to be organic? It doesn’t have to be, it won’t affect the organic growing of your plants, but we always like to support those who are making organic products. Consider (Public Goods) if that’s your jam. 

Hot tip: this works for a lot of bugs hanging out on your plants, if others come. Never a bad place to start. You can also wet a paper towel with the soap and gently rub them off your plant.
