Soap spray

Soap is another amazing ingredient that can help you get rid of bugs. You don’t want any pests destroying the garden that you worked so hard on!

Also, don’t forget to mix the two ingredients very well.

Neem oil spray

Neem has been used for a very long time in medicine as an amazing natural ingredient. Now you can fight the bugs in your vegetable garden with neem oil. Thanks to its bad smell and bitter taste, bugs will stay away from the plants and you will be able to avoid using chemicals.

The oil is extracted from the neem tree that grows mainly in India. Although it can affect pests, it’s not toxic to people, animals, or birds and it can be used for cooking.

Diatomaceous earth

Pest control will become much easier once you learn how to use diatomaceous earth. This insecticide comes with a complicated name, but it does an amazing job at keeping your garden safe from bugs. You can use it to get rid of aphids, crickets, snails, centipedes, Japanese beetles, and more. It’s most effective for bugs that get in touch with the garden or crawl on the area where you sprinkle it.

Diatomaceous earth comes from a rock that is created with algae called diatoms. You can find it in many garden stores. This natural ingredient uses dehydration as a mechanism to kill bugs. It strips their lipids, dehydrates them and solves your pest problem. To apply it, you just need to sprinkle it on the soil or on the plants.

Diatomaceous earth does the best work when you add it to a dry area. You should avoid using it right after it’s rained or after you’ve watered the plants. So, apply it when the soil is dry and it will stay on top of the soil. Water can transfer it to the lower parts of the soil, and that’s something you don’t want to happen. First, sprinkle it on the plants while the soil and area are dry. If it rains, you should repeat the process. You should also avoid using it on flowers.

Garlic spray

Bugs hate the strong scent of garlic, so it’s only logical to use this vegetable to fight those little pests. They are so unhappy with it that they decide not to feed on vegetables. This is great news since most of us already have garlic at home. It makes the whole experience effortless, plus cost-efficient. Although it’s still not completely clear whether garlic kills insects or just repels them with the scent, it still does a good job at keeping them away from your vegetables.

To protect your vegetable garden all you need is 10 to 12 garlic cloves, a quart of water, and a blender. Fill the blender with the garlic cloves and blend to get a puree. Next, add the water and mix the ingredients together. Leave the garlic spray overnight and use a strain to transfer it into a quart jar. To finish the recipe, you will need to also add one teaspoon of mild liquid soap and fill the rest of the jar with water.

Before using the garlic spray, you will need to dilute one cup of the mixture with one quart of water. You can fill it in a spray bottle for simple use.

To upgrade the recipe and make it stronger you can add half a cup of vegetable oil or one tablespoon of cayenne pepper. After you add these ingredients you need to let the mixture sit overnight and strain it again. Dilute with water before using it as we described above. Feel free to use it for several weeks, it won’t go bad. Just keep it in a cool and dark spot.

Chile pepper spray

This is another powder that you probably have in your kitchen cabinets. Hot peppers are hot and can be very irritating to bugs. It’s most effective for squash bugs, aphids, and Japanese bean beetles. Before you start making any recipe make sure that you’re careful because hot peppers can be irritating to the skin, eyes, nose.

If you want to prepare a chile pepper spray you will either need chile pepper powder or fresh hot peppers. Combine one tablespoon of powder, a few drops of mild liquid soap, and one quart of water. Mix all the ingredients together. Transfer the mixture to a spray bottle and you’re ready to go. If you only have fresh hot peppers, don’t worry, we’ve got a recipe for you as well. Blend half a cup of hot peppers in your blender with one cup of water. Once you’re done, add one quart of water to the mixture. Let it boil and leave it on the side. Wait for the mixture to cool down and use a strain. Include a few drops of mild liquid soap and transfer it to a spray bottle.

You can apply it in the evening so that it does its magic during the night when the pests come out. The spray is effective for up to one week, after that, you’ll have to reapply it. After picking your vegetables, wash them very well.

Tomato leaf spray

If insects have been all over your vegetable garden, it’s time to spur into action. Did you know that the leaves of tomatoes can help you get rid of these pests? Let’s start with the fact that these leaves contain alkaloids that are successful in the fight against bugs. Tomatine and solanine are the two chemicals that do the job.
