Few Common Houseplant Pests
2. Spider Mites
3. Scale Insects
Scale insects suck the sap out of plants, leading to slow plant growth. There are many species of these bugs, so look out for either round or oval-shaped brown insects on the stems and leaves. Eliminating scales infection is not easy. Insecticides often do not penetrate in their solid shells.
These bugs are a species of sap-sucking scale insect. They create a white, cottony appearance on indoor plants, and get collected on the undersides of leaves and plant nodes. They are difficult to remove. If you observe them on houseplants, cut off the affected branches. Alternatively, rub the mealybug with a cotton ball soaked in isopropyl alcohol.
Thrips are small insects that can damage the plants. They eat in groups, sucking leaves, flowers and even fruit. These pests feed on leaves and flowers, discoloring and deforming them. Look for brown-colored specks.
Whiteflies are white, gnat-like insects that feed on plant leaves. They will turn leaves pale yellow or white in heavy infestations. Whiteflies reproduce very quickly, therefore catching them soon will make them easier to get rid of.
7. Fungus Gnats
- While choosing indoor plants, make sure you are aware of their care needs and any specific problems to which they are susceptible.
- A careful checking of the plant before buying / bringing them indoors is a must.
- Meeting the environmental needs of plants will entail a healthy plant less vulnerable to pest attack.
- In case pest-control is required, non-toxic or less-toxic insecticides should be preferred.
