If you don’t want to use chemicals, there are natural ways to kill aphids. A much cleaner and safer approach to combat these pesky garden pests.

Plant Smartly and Carefully

One way to get rid of aphids is to grow the plants that repel them between the rows of your vegetable patches, garden beds and ornamental plants that are particularly loved by aphids.
You have to remember that a few plants (consider eggplant) are more vulnerable and preferred by aphids, if planted together they form an ideal place for feeding and development of them. If such plants are grown apart in the garden, it makes difficult for them to reach and infect.

Plants that Repel Aphids

If there are plants like aster and crape myrtle that lure aphids, there are plants that repel them. Grow flowers like marigolds, nasturtiums, and sunflower in your garden. In herbs, plant catmint, lavender, turmeric, ginger, oregano, etc.. Vegetables that aphids don’t like are onion and garlic.
