This solution works fully on scale insects and soft-bodied bugs (e.g. aphids, mealybugs). However, it works on different levels against fleas, chiggers, scales, and mites.

Neem Oil or Insecticidal Soap?

Till now we’ve covered up the basics of neem oil and soap for plants. And there’s no clear winner here. Like you cannot wait for a week till your oil solution starts working. On the other hand, causing harm to the environment shouldn’t be an option while killing insects.

Moreover, regular chemical soaps may also kill helpful bugs. But neem oil is perfect in this scenario.

But just as we said before, 1 week is enough time for the bugs to kill your precious garden. But this is a preventive measure. And because of that, it’s pretty popular.

On the other hand, some gardeners prefer short time harm instead of seeing their garden getting destroyed.

And many use a combination of both solutions to tackle those garden bugs. However, using this neem oil and soap pesticide combo still doesn’t solve some issues.

So, we have figured out a way to solve all the issues here.

The solution is to make an insecticidal soap with neem oil. We’ll explore this solution in the next part.

Neem Oil Insecticidal Soap Recipe

The best thing about soaps is that you can make these with any kind of oil. Actually, that’s basic organic chemistry. All you need is oil, lye, water, and some heat. You’ll end up with a functioning soap.

Now, let’s go through the details-


You’ll need to order up some ingredients before crafting this soap. For your ease, we’ve listed up the items with their amounts. Now, let’s get going-

  1. Neem oil – 1 pound
  2. Lye or caustic soda – 2.1 ounces
  3. Water – 0.2 pound
  4. A porcelain bowl
  5. A steel rod for steering

If you don’t have a porcelain bowl then look for heat resistant glass bowls. However, avoid using aluminum and plastic.


At first mix the first three ingredients in that bowl. Next start heating the bowl from bellow. Keep on steering the mixture.

Stop steering once you feel that the mixture has gone sticky. Now, let the mixture cool down for some time. After the cooling period, store it in a dry place for the pesticide making procedure.

At this point, you have a soap made out of neem oil. Now, it’s time to turn it into a pesticide.

Preparing the Pesticide

This part is actually super easy. All you have to do is measure the water against the soap. Your soap will measure around 1 pound. And, there’s a possibility that you won’t need all that soap at once.

So, we suggest you use that soap in parts.

Now, back to the procedure. Here you have to decide the pesticide concertation. For this, we’d suggest you follow the regular insecticidal soap concentration.

Once everything’s set, proceed to the next step. That is boiling the soap in water.

Once the new mixture gets cold, pour it in a spray bottle and start sweeping the war zone.

And that’s how to make insecticidal soap with neem oil.

Safety Measures

Don’t go anywhere near soap making without proper safety measures. Now, what are the safety measures here? Well, regular stuff like gloves, goggles, aprons, etc.

Believe us you don’t want that lye going into your eyes. Even touching it gives burning sensations. So, take proper safety measures.

Also, clean the materials properly after use. Because someone might use that bowl for eating something. And soaps getting inside your belly isn’t a pretty feeling.
