How to Make Natural Insecticide


Using natural insecticides are the best choice when it comes to killing insects in your garden. Some insects are beneficial, however. Beneficial insects include ladybugs, spiders and lacewings. These bugs keep the other insects away and eat such predators as aphids and spider mites. There are several types of natural pesticides. Garlic spray is an excellent insecticide and controls fungus as well.

Step 1

Place the garlic in the mineral oil in a pint jar for a minimum of 24 hours.

Step 2

Add ¼ ounce of liquid soap to the pint jar mixture and fill with water after the 24-hour soaking period.

Step 3

Stir thoroughly or replace the lid on the pint jar and shake vigorously.

Step 4

Strain the mixture into another pint jar to store. This recipe is a concentrate and will make enough for several applications. Keep it in the pint jar and use it as needed.

Step 5

Transfer 1-to-2-tablespoons of the concentrate to a spray bottle and fill with water.

Step 6

Thoroughly spray the plants on the top and bottoms of the leaves and along the stems. Make sure the plant is thoroughly treated. If after 1 to 3 days, you still notice pests, make your solution in the spray bottle stronger by adding one extra tablespoon of concentrate to increase the strength. Spray the plants again.
