Although beneficial and necessary to our ecosystem, insects can be quite bothersome in the home and garden. Many commercial insect repellents contain toxic chemicals that are not only bad for your health, but bad for the environment. Make your own insect killer instead. Homemade insect repellent can be just as effective as the commercial types, but does not pose health hazards.
Place four garlic cloves, one jalapeno pepper and a small onion into a blender. Use the "Crush" button to mix the ingredients.
Pour one quart of warm water into the mixture. Let it soak for about two hours.
Use an old pair of panty hose or a cheesecloth to strain the mixture. Hold the panty hose over a large bowl or gallon jug and pour the mixture slowly into the panty hose. This will strain all of the larger pieces of the mixture.
Pour the mixture into a one-gallon jug. Add 1 tsp. Murphy's Oil Soap and 1 tsp. vegetable oil. Fill the rest of the jug with warm water.
Put the lid on the jug and shake the mixture to combine the ingredients. Transfer the homemade insect killer to a garden sprayer.
Boil one pint of water. Remove it from the heat once it begins boiling.
Grate the rind of one lemon into the hot water. Let the lemon and water sit overnight to steep.
Use a piece of cheesecloth to strain the mixture of the lemon rinds into a large boil. Transfer the mixture to a garden sprayer and apply to plants and landscaping.
Combine 1 tbsp. of dishwashing detergent and 1 cup cooking oil into a gallon jug. Store this mixture in an air-tight container, as this will make more than one batch of insect killer.
Add 5 tbsp. of the detergent and oil mixture into a gallon jug of warm water. Shake the jug to thoroughly combine the ingredients.
Transfer the mixture to a garden sprayer and apply to your plants.
Test the insect killer you are using on a plant that is already infested or damaged prior to applying to other plants. This will ensure the solution will not harm your plants.
