What are Aphids?
Aphids are small, soft-bodied insects that can be found on a wide variety of plants. They are typically less than one-eighth an inch long and vary in color from a very pale pink to green. Aphids feed on the sap of plants by sucking out the juice, which can damage or even kill the tomato plant. They tend to cluster together and like to be on the underside of leaves and in the crevices of stems. Aphids aren't just a problem for tomatoes though; these bugs also feed on other vegetables like peppers and cucumbers, flowers including knockout roses, shrubs, and trees.
“Aphids feed on the sap of the tomato plant.”
Why are Aphids Harmful to Your Tomatoes?
Aphids can be very harmful to tomatoes for several reasons. First, aphids have piercing mouth parts that allow them to suck out the plant's nutrients from its leaves and stems. They feed on the sap of the plant, which can damage or even kill it. This can stunt the tomato plant's growth and lead to lower yields.
Second, aphids spread diseases from plant to plant. Plant viruses can be transmitted when aphids feed on infected plants, then move to other tomato plants.
Third, aphids produce a sticky substance called honeydew that attracts ants and creates an ideal environment for mold growth. This can lead to further damage from fungus-like powdery mildew.
Finally, aphids can reproduce very quickly. A single aphid can lay up to 100 eggs in a lifetime, and a colony of aphids can increase its population size very quickly. Don't let a small problem turn into a big one - aphids can quickly take over your tomato plants if left unchecked!
Signs of Aphid Infestation /Damage
An aphid infestation is not always easy to spot, but there are a few signs that can help you identify them. The first sign is the presence of aphids themselves! They usually range from white or green in color and are small, soft-bodied insects.
If you see clusters of aphids on the underside of leaves or in the crevices of stems, then that's a good indication that there is an infestation.
If aphids have been feeding on the tomato plant, then the leaves may begin to turn yellow. Make sure to check each tomato leaf carefully for signs of these pests.
The aphid's saliva can also cause malformed and curled leaves or distorted flower buds. The aphids' excrement (known as honeydew) is often a sticky substance that will appear on the stems of plants.
Other signs include wilting stems from sap loss due to aphid feeding habits.
Identifying aphids is really important to protect your tomato fruit. It is better to catch them early before you have a full-blown aphid infestation.

You can also try companion planting chives and garlic nearby.

Beneficial insects can also help control aphids on tomato plants. Ladybugs, lacewings, and aphid midge larvae are all good aphid predators that will eat aphids like candy!
Ants like to carry aphids, so spread bone meal around ant holes to deter them.
Spray tomato plants with neem oil, which is an organic pesticide made from the Neem tree. It works by suffocating the aphid and preventing them from breeding.
You can also fill a spray bottle with soapy water and spray the aphids directly. This method will need to be repeated frequently.
Row covers can also be draped over the plants to keep aphids from getting to them.

Aphid Prevention Tips
The best way to prevent aphids from attacking your tomato plants is by keeping them healthy. Healthy tomato plants have fewer aphid problems than unhealthy ones do.
It is important to inspect your tomato plant leaves frequently for aphids. This is the best way to catch aphid infestations early before they get out of control. Here are some ways you can do it:
- Inspect tomato plants for aphids every time you harvest tomatoes or water your tomato garden.
- While inspecting, pay special attention to new growth and leaf undersides where aphids like to feed and lay eggs.
Companion planting can offer numerous benefits when it comes to aphid control. Some plants that work well as companion plants for tomatoes include:
- nasturtiums
- garlic
- chives
- marigolds
-rhubarb
Introduce beneficial insects into your garden. Aphids are also susceptible to natural enemies such as ladybugs, lacewings, and parasitic wasps.
Use natural sprays like neem oil or insecticidal soap to wash away aphids.
- Add two tablespoons of castile soap into one gallon of water, then spray aphids directly.
- Add two teaspoons of neem oil to one gallon of water, then spray aphids directly.
Be sure to cover both the top and bottom of leaves when spraying aphids. This will help ensure that you get all the aphids on your plants.
Apply yellow stick boards around your tomato plants to attract aphids. Aphids are attracted to yellow and will travel towards it, then stick inside its glue coating. It is an effective aphid control method when used alone or in combination with aphid sprays like neem oil or Castile soap.
Lastly, you can place row covers over your tomato plants to prevent aphids from getting onto the plants.
