How To Make Natural Homemade Bug Spray For Vegetables

Homegrown vegetables have always seemed a bit more delicious and healthier than the ones we can get in supermarkets.

Of course, that’s because they are grown very carefully and with love.

Plus, people who grow vegetables at home tend to carefully pick the products they use to take care of their plants. Of course, these are often homemade bug spray for vegetables.

Not everything is perfect when it comes to growing your own plants, though. You have to be cautious about a number of different things.

Whether the soil is good enough, do you water enough.

You have to make sure your plants get enough nutrients so they wouldn’t get some disease that would cause them to wither and eventually die.

And of course, there is the problem of insects and pests, that can be very annoying at times, by causing plants to lose their properties and eventually wither.

There are a lot of some good products, like this insect killer that I sometimes use and that can deal with this problem.

But still, all of them contain a certain amount of bad chemicals. Therefore, you probably want to go with homemade bug spray for vegetables first.

I am here to help you with that, so stay tuned and let’s begin!

1. Homemade Bug Spray With Oil

Homemade Bug Spray With Oil

The first homemade bug spray for vegetable plants I will mention is the one made of vegetables to help other vegetables. Sounds crazy, I know, but it is true. You can use vegetable oil and mix it with a bland soap.

This type of spray is very effective against multiple types of insects. For example, aphids, several types of mites and flies.

How does one make this spray, you may ask? It’s easy, just look at the ingredients below.

  • 1 cup of vegetable oil
  • 1 tablespoon of soap

That should be mixed properly, and when you want to use it, just do the following:

  • 2 teaspoons of the mixture combined with 1 quart of water and use the spray on the insects

How does this actually work? Well, the mixture in question blocks the spores, which insects use for breathing. In this way they suffocate and die, thus leaving your plant in peace. It’s a great natural diy bug spray for vegetable garden, that I highly recommend.

What makes this bug spray for vegetables very popular is that it is fairly easy to make and use.

With it, you won’t have to worry about some complicated ingredients and that kind of stuff.

All you should note is that it is preferable to use it when it is not too hot and sunny. I would suggest it be during the evenings or even very early mornings.

2. Homemade Bug Spray With Soap

A spray made of soap is very similar to the previous one, made of vegetable oil.

The same concept applies here. You need to mix a certain amount of soap with a certain amount of water in order to get the mixture you need.

This type of spray is very effective against multiple types of insects, such as aphids, several types of beetles, mites and a couple types of flies, such as whiteflies.

So it can be very effective when you need to get rid of the small insects in very short notice because it is fairly easy to make.

In order to make this type of bug spray for vegetables you need the following ingredients:

  • 1 teaspoon of a bland soap, preferably liquid soap,
  • 1 quart of water

Both should be properly mixed, and once it is done, the mixture is ready to use.

It works the same way as the spray made of vegetable oil. So, what you need to do is apply it on a vegetable where the insects are, and then it will do its job.

This bug spray for vegetables is very easy to make and use, so we can say that it is very useful when you need to deal with the pests in short notice.

Same as with the previous spray, it gives the best effects if not used when it is too hot or too sunny.

So, you should use it late in the evening and early in the morning.

3. Homemade Organic Bug Spray For Vegetable Plants Made Of Neem Oil

Homemade Bug Spray Made Of Neem Oil

One of the most powerful natural insecticides can be found in a neem tree seed.

Oil extracted from it can further be used to create a mixture that can function as a very useful bug spray for vegetables and other plants.

It is considered very powerful because it is capable of stopping the insects, even in the early stages of their development.

Its effectiveness ranges from when they hatch to larvae and ultimately when they are in the adult stage.

Another very useful feature neem oil has is that it cannot hurt birds, pets and other animals, because it is biodegradable.

Apart from that, it is very useful when it comes to dealing with all types of common garden pests and can also be used to fight fungal infections if the need arises.

So how you should use neem oil to make a homemade bug spray for vegetables?

Probably the best idea is to read what is the right dosage on the bottle, but you can also experiment with it by starting with the following ingredients:

  • 2 teaspoons of neem oil
  • 1 teaspoon of bland liquid soap
  • 1 quart of water

You should shake the mixture very properly and then apply it to the specific spots on the vegetable where the problem occurred.

Neem oil spray should quickly deal with the problem in question.

Apart from being used when the insects had already attacked the plant, neem oil bug spray can be used as a prevention against future insect attacks.

If you have done your research and saw that the vegetable or plant you grow is on the list of plants that have a higher risk of being infested, then you can just use neem oil as a prevention and spray plant’s leaves.

4. Homemade Bug Spray Made Of Garlic

Apart from being known to repel vampires, garlic can also be used to create your own homemade bug spray for vegetable garden and other plants.

It is usually debatable if garlic can really be considered as an insecticide or can it just be used for repelling the pests.

Whatever the truth is, it is known that mixture made of garlic can actually get rid of the insects, one way or another, which really does not matter much, as long as they are gone.

Therefore, let’s see what do you need in order to make this spray. Do the following:

  • Blend 2 bulbs of garlic with some water and leave it to stay overnight
  • Put the mixture into a quart jar and add 1/2 cup of vegetable oil if you want
  • 1 teaspoon of bland soap, preferably liquid
  • Rest of the jar filled with water

Now when the mixture is done, in order for you to use it just do the following:

  • 1 cup of mixture mixed with
  • 1 quart of water

After that, your mixture is ready to be used and applied onto the plant.

The effect it produces is that it usually repels insects and other pests, which is ultimately the goal.

The advantage of this spray is that all the materials you need can be found in your home, so it is fairly easy and budget-friendly to make and use.

5. Homemade Bug Spray Made Of Chilli Pepper

Same as with garlic, it is debatable whether chilli pepper is just a repellent or it could be considered a natural insecticide as well.

Anyway, it is fairly easy to use, and it will get the job done, so it really doesn’t matter in which category we will put it.

There are two ways to make bug spray for vegetables made of chilli pepper. Firstly, you can use powder pepper and secondly, you can use the whole pepper to do it.

We will list both ways underneath. So, you need to do the following:

Chilli pepper powder

  • 1 tablespoon of chilli pepper powder
  • Several drops of bland liquid soap
  • 1 quart of water

Whole chilli pepper

  • Blend 1/2 cup of chilli peppers with
  • 1 cup of water
  • Add 1 quart of water and boil the mixture then wait until it cools off
  • Remove chilli material
  • Add couple drops of bland liquid soap

When you have prepared the mixture, you are ready to use it.

But before you do so, you should put some gloves on and make sure the spray doesn’t get in touch with your eyes and nose.

It could produce a very unpleasant feeling.


1. Is it recommended to use garlic mixture as prevention against possible insect attacks?

Absolutely! Since garlic is used to repel the pests, it shouldn’t do any harm to the plant itself. If you are still not too comfortable doing it, you can use neem oil spray as prevention instead.

2. Is it ok to add more materials than suggested?

Sure it is, but you have to be careful and use more water to dilute the full mixture before using it.


Hopefully, you got some good ideas from me and from this short guide. Of course, you can always use beneficial insects to help you get rid of pests in your indoor garden. But these homemade bug sprays can never hurt!
