How to Make Your Own Insecticide


Insects are a fact of life in the garden. To cope with sudden infestations, many gardeners rely on insecticides containing chemicals. But some gardeners worry about the long-term effects that these chemicals may have as they leech into ground water and end up in the water we drink. Because of this, some gardeners resort to making their own insecticides. Effective insecticides can be created using common household products.

Insecticide Soap

Step 1

Mix 5 tbsp. dish washing detergent with 1 gallon warm water.

Step 2

Pour the mixture into a spray bottle.

Step 3

Spray insects whenever you see them. Detergent is a contact insecticide and kills pests when directly applied.

Step 4

Place the bucket of soapy water near your plants. Hand pick bugs from your plants and throw them in the soapy water to kill them.

Insect Repellent

Step 1

Crush 5 cloves of garlic and soak them in water.

Step 2

Pour garlic water into a spray bottle.

Step 3

Spray the foliage of your plants with garlic water. The scent will drive away insects.
