Natural insect repellants are often non-toxic to humans and pets and safe for the environment. The simplest homemade insect repellent combines water and liquid soap. You can also make a natural insect repellent based on neem oil or from your own garden. You can make a natural insect repellent with ingredients purchased from stores or markets, garden centers, or herb stores.

To step

Method 1 of 4: Insect repellent with soap

1. Make a basic insect repellent at home by mixing two tablespoons (30ml) of liquid soap with 1 liter of water.
2. Mix a stronger insect repellent with soap by adding a garlic bulb, a small onion, a tablespoon (15ml) of red cayenne pepper to the liquid soap and water.
   • Finely chop the onion and garlic and mix it with the water.
   • Add the cayenne pepper and let the solution sit for an hour.
   • Add the soap and mix the solution well.
   • When the foam dissolves, strain the solution and pour it into a spray bottle. Keep the solution with the herbs refrigerated for up to two weeks.
3. You can sprinkle the mixture on your plants, or you can put the mixture in a spray bottle and spray your plants. Spray evenly. Spray the natural insect repellent directly on insects when you see them.

Method 2 of 4: Insect killer with neem

1. Make a mixture of neem oil, rosemary and lavender essential oils, and water for a natural bug repellent that also kills fungi and mites. Neem oil, made from neem tree seeds, is available online, at garden centers, and at some bargain markets.
   • Take a liter of water and add 30 ml of neem oil to it.
   • Add 2.5ml of rosemary essential oil and 2.5ml of lavender oil. You can buy essential oils online, at health stores, herbal stores, vitamin stores, and farm stores.
   • Add 30ml of liquid dish soap to make the insect repellent more effective.
   • Mix thoroughly and pour into a spray bottle.
2. Spray your plants, shaking your solution regularly while spraying as oil and water separate.

Method 3 of 4: Wormwort insect repellent

1. Grow wormwort in your garden so you have the main ingredient for your repellent - wormwort, which quickly wilts. Wormwort has been used in insecticides for sale for years. Wormwort is also known as pyrethrum.
   • Pick the flowers when they are in full bloom.
   • Hang the flowers in a dark, dry place to dry.
   • Chop the flowers finely in a blender or with a mortar. The finer the mince, the more effective the insecticide will be.
2. Apply it to your plants with an insecticide brush.
   • Or make a solution of 10 grams of finely chopped worm herb in three liters of warm water. Let the solution sit for three hours.
   • To make it more potent, add a teaspoon (5ml) of sesame oil or liquid dish soap.
3. Spray it on both the top and bottom of the leaves of your plants, as the worm weed must come into contact with the insects. Spraying can make pests agitated, so spray again if you see them moving around.
   • Spray when it's cooler outside, as worm weed is most effective at lower temperatures.

Method 4 of 4: Insecticide with ammonium sulfate

1. Add a tablespoon of ammonium sulfate to a quart of water.
2. Then add a tablespoon of dish soap per liter of water.
3. Shake to mix well.
4. Pour it into a spray bottle. Label the bottle so you know what's in it.
5. Spray it on stems and leaves. Ammonium sulphate is a very good, inexpensive fertilizer and is harmless to plants. It is also non-toxic to mammals and safe in an aquatic environment.

Warnings

• In some countries it is illegal to make your own insect repellent. This is not the case in the Netherlands.
