Plants That Deter Aphids Effectively (Top Picks)

There are several plants that can effectively deter aphids from infesting your garden. In this article, we will discuss three such plants and their benefits in repelling aphids.


Marigolds are not only beautiful flowers but also excellent natural repellents for aphids. These vibrant plants emit a strong scent that repels aphids and other common garden pests. The pungent odor of marigolds acts as a natural deterrent, making it difficult for aphids to locate and feed on nearby plants.

Additionally, marigolds contain a compound called limonene, which is toxic to aphids. This compound disrupts the aphids’ nervous system, discouraging them from settling on or near marigold plants.

Planting marigolds around your garden or interspersing them among susceptible plants can create a protective barrier against aphids. They are particularly effective in repelling green peach aphids, which are known to cause significant damage to various crops.

2. Chrysanthemums

Chrysanthemums, commonly known as mums, are another powerful deterrent for aphids. These colorful flowers contain natural insecticides called pyrethrins, which are toxic to aphids and many other garden pests.

Pyrethrins attack the nervous system of aphids, causing paralysis and eventually leading to their demise. By planting chrysanthemums in your garden, you can effectively repel aphids and keep your plants safe from their destructive feeding habits.

It is important to note that while chrysanthemums are effective in repelling aphids, they can also harm beneficial insects such as ladybugs and bees. Therefore, it is advisable to use chrysanthemums strategically and sparingly, focusing on areas where aphid infestations are prevalent.

3. Nasturtiums

Nasturtiums are versatile plants that not only add beauty to your garden but also act as a natural aphid repellent. These vibrant flowers produce a mustard oil compound that aphids find highly unappealing.

The pungent scent and taste of nasturtiums act as a deterrent, making aphids less likely to settle on nearby plants. Additionally, nasturtiums can attract aphids away from other more susceptible plants, acting as sacrificial hosts.

Planting nasturtiums as a border around your garden or near plants that are prone to aphid infestations can help protect your crops. However, it is important to regularly monitor the nasturtiums for aphids and remove any infested leaves or flowers to prevent the pests from spreading.


By incorporating marigolds, chrysanthemums, and nasturtiums into your garden, you can effectively deter aphids and protect your plants from their damaging effects. These plants not only repel aphids through their scents and compounds but also add beauty and vibrancy to your outdoor space.

Remember to strategically place these plants in your garden, focusing on areas prone to aphid infestations. Regular monitoring and maintenance are essential to ensure the effectiveness of these natural aphid deterrents.
