Aphids: How to Identify, Control, and Eradicate Them

Aphids: How to Identify, Control, and Eradicate Them | Dallas Landscaping Services Company

Also known as plant lice, aphids come from the Aphidoidea insect family and includes a variety of species. There are more than 4,000 kinds, and approximately 200 of them are destructive to plants. 

They also come in a wide array of colors – some are black, green, white, reddish-brown, and gray. They feed on many plants, and in severe infestations, the plant fails to thrive.

Aphid identification

Aphids are small-soft bodied pests that pierce through the plant stems and suck out their nutrient-rich sap. They normally carry viruses as they feed and secrete “honeydew” in the process, creating a conducive environment for molds.  

Signs of an infestation

With their beak-like mouths, aphids suck the sap from the plant’s tender leaves and shoot. The damage they create is two-fold: sucking the sap will weaken the plant and injecting its saliva will spread viruses to other plants – a lot of which are incurable. The “honeydew” that they secrete becomes infested with black sooty mold.  

One of the signs of a big aphid infestation is the presence of ants on your plants. Ants love sweet food, so it is very likely that aphids are present on your plants when you see a lot of ants on them. 

Watch out for these other signs:

•    Yellowing, curling, stunted, or misshapen leaves.
•    If the stems and leaves are covered with sticky honeydew.
•    The sooty mold will cause the branches and leaves to appear black.
•    An aphid infestation will also attract ladybugs.
•    Fruits or flowers can become deformed or distorted.

Aphid Control

An aphid infestation can be reduced naturally through heat, heavy rain, and high wind. Occasionally, all that aphids need is a blast of cold water to dislodge them.

If there is a huge infestation, insecticides may be needed. Aphids can easily be eradicated by standard pesticides. However, it’s best to use non-chemical ways to manage aphids, since a lot of chemical sprays will destroy the beneficial insects along with the pests. You may use a homemade garlic spray or tomato leaf spray to control aphids, but you would need to reapply once you notice the infestation reappears.
