Growing vegetables in your garden supply fresh produce your family while providing you full control of what is used and of their maintenance. Pest control is crucial to steer away pesky insects from gorging on your plants. Pesticides are an excellent choice, but they contain harmful toxins, leaving chemical residue on your yields.

Thankfully, there are homemade organic pesticide alternatives, which you can make from items readily available at your home. With these five natural pesticide recipes, you can now stave off unwanted visitors from your feasting on your vegetable garden the safest way possible.

#1 Neem Oil Insecticide

Neem oil is an extract from the seeds of the Neem tree (Azadirachta Indica), which originates from India and other parts of South Asia. For hundreds of years, it has traditionally used as an insecticide but also used as a raw ingredient for wax, soap, oil, and an array of cosmetic products.

How It Works

Neem oil disrupts the insect’s hormones, hampering their normal feeding habits. It disrupts the life cycle of insects, includes all other phases of their growth (the egg, larvae, and adult.)

Ingredients

  • 1 tsp liquid soap
  • 1-liter water
  • 2 tsp pure, cold-pressed Neem oil

Get a spray bottle and mix all the ingredients. Spritz the mixture on affected foliage of your vegetable and plants. Typically, one to two treatments are ample to free your greens of the pesky insects.

Don’t worry as the oil is safe to humans, pets, birds and is biodegradable. Make sure to use this in moderations as it can jeopardize the bees. They are crucial in the pollination process of some of your vegetables. So, It’s essential not to drive them away.

#2 Garlic and Cayenne Pepper Spray

If you’re dealing with more robust insects, time to use a more powerful organic pesticide. Combine the power of garlic and cayenne pepper into a mixture and get rid of leafhoppers, aphids, borers, slugs and cabbage loopers in a breeze.

How It Works

Most of these small critters simply don’t like the odor of garlic and cayenne pepper. Both ingredients contain substances that irritate them.

Ingredients

  • 4 cups, water
  • 1 tbsp liquid soap
  • 1 head garlic
  • 1 tsp powdered cayenne pepper
  • 1 small peeled onion

Put the water, chopped garlic head and onion and powdered cayenne pepper (flakes or fresh one would also do) in a large saucepan. Bring it to a boil and let it stay for 24 hours. Strain the mixture and pour it in a spray bottle. Spritz it in the affected plants as needed. You can store the liquid in the fridge and use it for up to one week.

Alternatively, you can also partner garlic with various home products such as salt, vinegar, baking soda, and horseradish. All would still be effective as organic pesticides.

If making a spray isn’t for you, why not plant garlic between your vegetables instead. Its veggie friends won’t mind its smell, but inspects will surely refrain from your garden.

#3 Diatomaceous Earth

Diatomaceous earth is a kind of powder derived from the sediment of fossilized algae, called diatoms, found in bodies of water. It has a variety of uses around the home but can also serve as an effective insecticide.

How It Works

Diatomaceous earth has abrasive features and the capacity to absorb lipids from the insects’ exoskeletons. Eventually, it forces dehydration and death among the insects who got in contact.

Ingredients

1 bag Diatomaceous Earth

Sprinkle diatomaceous earth on the foliage, or dust the soil around the plants. Make sure to reapply it after every rain to get its full effect.

#4 Oil Spray Insecticide

Natural and essential oils are a staple part of every home. While they are widely used for their primary purposes, natural oils (mineral, vegetable, etc.) and essential oils (citronella, lavender, etc.) are also efficient in steering pests away.

How It Works

These oils coat the insects’ bodies and cut their oxygen supply, eventually suffocating them to death. They are commonly in fighting a wide array of insects such as thrips, mites, aphids, and mealybugs.

Ingredients

  • 1 cup of natural or essential oil
  • 1 tbsp of soap
  • 0.5 liter

Shake the oil and soap to get the standard oil you can use for staving off these little creatures. Dilute 3-4 tsp of the mixture in half-liter of water and put in a spray bottle. Spritz it directly on the affected plants.

Don’t overuse it, however, especially on hot weather. Too much oil can be harmful as it may burn your plant’s foliage when exposed directly to the heat of the sun. Applying it once a week is good enough to keep pests away.

#5 Tomato Leaf Spray

Are you growing tomatoes in your vegetable garden? Why not use it to protect its veggie neighbors? Tomato leaves are effective against many herbivorous insects and have many properties enough to keep them away.

How It Works

Tomato plants have a natural glycoalkaloid called Tomatine (Solanum Lycopersicum). The substance has antimicrobial, fungicidal, and insecticidal properties. While safe for plants and humans, it is toxic for most insects.

Ingredients

  • Tomato leaves
  • 3 cups, water

Fill a cup with tomato leaves and add two cups of water. Let it stay for 24 hours. Then, strain it and add another cup of water. Pour the liquid into a spray bottle and spritz it on the foliage of the affected vegetables.
