Updated: July 21, 2023

If you are a plant lover, you know how frustrating it can be to discover that your cherished greenery is under attack by pests. Plants are not immune to pests, and even the most well-cared-for plants can fall victim to infestations. In this article, we will discuss the most common plant pests that afflict plants from The Sill, a popular online houseplant retailer, and provide an identification and treatment guide to help you keep your plants healthy and thriving.

Fungus Gnats

Fungus gnats are small flying insects that resemble tiny mosquitoes. They are attracted to damp soil and decaying organic matter, making potted plants an ideal breeding ground for them. Fungus gnats lay their eggs in the soil, and the larvae feed on the plant roots, causing damage and inhibiting growth.

To identify a fungus gnat infestation, look for small black flies hovering around your plants or crawling on the soil surface. You may also notice yellowing leaves or stunted growth in affected plants.

To treat a fungus gnat infestation, start by allowing the soil to dry out between waterings. This will help kill off the larvae as they require moist conditions to survive. You can also place yellow sticky traps near your plants to catch adult gnats. If the infestation persists, consider using an insecticidal soap or neem oil spray to control the population.

Spider Mites

Spider mites are tiny arachnids that are difficult to spot with the naked eye. They typically infest indoor plants during dry and warm conditions. Spider mites feed on plant sap by piercing the leaves with their mouthparts, causing yellowing leaves, stippling, and webbing between leaves and stems.

To identify a spider mite infestation, inspect your plants for fine webbing on the undersides of leaves. You may also notice small, yellow or brown dots on the leaves and a general decline in plant health.

To treat a spider mite infestation, start by isolating the affected plant to prevent the mites from spreading to other plants. Increase humidity around the plant by misting or using a humidifier, as spider mites thrive in dry environments. Regularly wash the leaves with water to remove the mites and their webbing. If the infestation persists, consider using an insecticidal soap or neem oil spray to control the population.

Mealybugs

Mealybugs are tiny, soft-bodied insects that feed on plant sap. They are covered in a white, waxy substance that resembles cotton or meal, hence their name. Mealybugs can be found on stems, leaves, and the undersides of leaves, often hiding in crevices.

To identify a mealybug infestation, look for small white cottony masses on your plants or sticky honeydew residue on leaves and surrounding surfaces. You may also notice distorted growth or yellowing leaves.

To treat a mealybug infestation, start by physically removing the bugs with cotton swabs dipped in rubbing alcohol or soapy water. Pay close attention to hidden areas where mealybugs tend to congregate. Apply a systemic insecticide to the soil to kill any remaining bugs and prevent future infestations.

Scale Insects

Scale insects are small, immobile pests that attach themselves to plant stems and leaves. They have a protective shell-like covering that makes them difficult to spot. Scale insects feed on plant sap by inserting their mouthparts into the plant tissue, causing yellowing leaves, stunted growth, and leaf drop.

To identify a scale insect infestation, look for small brown or black bumps on your plants’ stems and leaves. These bumps may have a shiny or waxy appearance. You may also notice sticky honeydew residue on leaves and surrounding surfaces.

To treat a scale insect infestation, start by physically removing the insects using a cotton swab dipped in rubbing alcohol or soapy water. Pay close attention to hidden areas where scales tend to congregate. If the infestation is severe, consider using an insecticidal soap or horticultural oil spray to control the population.
