Homemade Vegetable Plant Insecticide Spray


Insects love the vegetables in your garden as much as you do. And a virulent infestation can ruin a crop of vegetables. However, commercial pesticides are not the answer. You'll end up eating them once they are absorbed by your veggies, and many insects eventually develop an immunity to them. A simple homemade organic spray will effectively repel common garden insects--such as white flies, aphids, spider mites and caterpillars--without contaminating your vegetables.

Step 1

Peel the garlic.

Step 2

Add the water, pepper sauce and garlic into the blender and blend until the consistency of the mixture is even.

Step 3

Strain the mixture through the strainer and into the spray bottle.

Step 4

Spray the vegetable plants once a week in the early morning or late afternoon and after rain. Pay close attention to the tops and bottoms of the plant's leaves.
