Identification and Treatment Guide

Updated: June 22, 2022

Dollar Tree plants are an affordable way to add some greenery to your home or garden. However, like any other plant, they can be susceptible to pests. In this article, we will discuss the most common Dollar Tree plant pests, their identification, and treatment methods.


Aphids are tiny, pear-shaped insects that typically feed on the sap of plants. They are usually green or black in color and can often be found in clusters on the undersides of leaves. Aphids can cause stunted growth in plants and transmit viruses.

Treatment: Aphids can be controlled by spraying the affected plant with a strong jet of water or by using insecticidal soap or neem oil.

Spider Mites

Spider mites are very small arachnids that feed on plant sap. They suck the chlorophyll out of leaves, causing them to turn yellow and eventually die. Spider mites are often identified by the fine webbing they produce on the plant.

Treatment: Spider mites can be controlled by regularly washing the plant with water or using insecticidal soap or neem oil.


Mealybugs are soft-bodied insects that produce a white, cottony coating on the plant. They suck the sap from leaves and stems, causing yellowing and stunted growth.

Treatment: Mealybugs can be controlled by wiping the plant with a cotton swab dipped in rubbing alcohol or using insecticidal soap or neem oil.

Scale Insects

Scale insects are small, oval-shaped insects that attach themselves to the stems and leaves of plants. They feed on sap and can cause yellowing and wilting of leaves.

Treatment: Scale insects can be controlled by scraping them off the plant with a soft brush or using insecticidal soap or neem oil.


Whiteflies are small, winged insects that feed on the sap of plants. They can cause yellowing and wilting of leaves and transmit viruses.

Treatment: Whiteflies can be controlled by spraying the plant with a strong jet of water or using insecticidal soap or neem oil.

Fungus Gnats

Fungus gnats are small, black flies that are attracted to moist soil. They lay their eggs in the soil, and the larvae feed on plant roots, causing stunted growth.

Treatment: Fungus gnats can be controlled by allowing the soil to dry out between waterings and using sticky traps or mosquito dunks.


Are Dollar Tree plants more susceptible to pests than other plants?

No, all plants are susceptible to pests. However, Dollar Tree plants may be more prone to pests due to their lower quality and lack of proper care before being sold.

Can Dollar Tree plants be saved if they have a severe pest infestation?

It depends on the severity of the infestation. If caught early, most infestations can be treated and the plant can recover. However, if left untreated for too long, the plant may not survive.

How can I prevent pest infestations in my Dollar Tree plants?

The best way to prevent pest infestations is to inspect your plants regularly for signs of pests and to quarantine any new plants before introducing them to your other plants. Additionally, providing proper care for your plants, such as adequate watering and fertilizing, can help keep them healthy and less susceptible to pests.

In conclusion, Dollar Tree plants can be a great addition to your home or garden, but they may require some extra attention when it comes to pest control. By identifying and treating common pests early on, you can help ensure the health and longevity of your plants.
