2 Parts: Steps Comments

Sap sucking critters also known as "aphids" are one of the top creepy crawlies that can destroy gardens and even devastate crops. The most important thing when you are dealing with food is that you need to get rid of these critters in an organic way before they infect the rest of the crops, so that you will have a bountiful and healthy harvest. That is why you cannot use those chemical filled insect repellents out on the market. The best way to get rid of these pesky critters is to make your own homemade and chemical-free insect repellent for aphids.


The best two insect repellents that you can make to battle aphids are made with tomato leaves and garlic. These two basic ingredients are found in households worldwide, and very easy to acquire, and the repellent is easy to make. You should utilize these harmless (to humans) repellent, but you should also know and understand why and how they can be effective in keeping these pests out for good. Let's talk about the garlic concoction: For a lot of years now, organic farmers have depended on the natural pest fighting power that garlic can pack. Its active ingredient that makes it very potentially harmful for aphids is sulfur, which makes it very harmful to pests and it also can be used as antibacterial and anti-fungal. Now the tomato leaf spray: Tomatoes naturally have alkaloids in their leaves. When these leaves get chopped, the alkaloids are released, and if diluted and immersed in water, it will make a spray that is safe for plants and humans, but lethal for aphids.

  1. 1
    What you'll need
    1. Garlic oil
    2. Four cloves of garlic (for more potency)

    6. Metal spoon
    7. 1 tsp. of liquid dish soap
    8. 1 pint of tap water
