Common Garden Pests

Some of the most common plant pests you may find on your balcony garden include the following;


Aphids are small, soft-bodied insects that come in various colors, including green, black, brown, and even pink. They have pear-shaped bodies and can be winged or wingless. When present in large numbers, they cluster on new growth and leaves, sucking sap and secreting a sticky substance called honeydew.


Whiteflies are tiny, moth-like insects that measure about 1/16 to 1/8 inch in length. They have white, powdery wings that create a cloud-like appearance when disturbed. When infested, plants may exhibit yellowing leaves and sticky honeydew residue.

Spider Mites

Spider mites are very small pests, barely visible to the naked eye. They can be red, green, yellow, or brown. They are arachnids rather than insects and leave fine webbing on the undersides of leaves. Infested plants may develop yellow speckles and eventually become discolored.


Mealybugs are small, soft-bodied insects covered in a white, waxy substance that resembles cotton. They have oval-shaped bodies and often cluster in hidden areas, such as leaf axils and plant crevices. Their feeding causes distorted growth and the appearance of sticky honeydew.

Scale Insects

Scale insects have a unique appearance, resembling tiny, oval or round bumps or scales that attach themselves to plant stems, leaves, or even fruits. They can be brown, black, or tan, and some have a protective shell-like covering. Infestations often lead to weakened plants and honeydew secretion.


Thrips are tiny, slender insects with long fringed wings. They come in various colors, including black, brown, or yellow. Infestations can cause silvery streaks or spots on leaves and petals, along with distorted growth. Thrips are known for their ability to transmit plant diseases.


Caterpillars are the larval stage of moths and butterflies. They vary in appearance, but most have soft bodies with distinct segments and may be brightly colored or camouflaged. They feed voraciously on leaves, causing noticeable chewing damage and even skeletonizing leaves in severe cases.

Fungus Gnats

Fungus gnats are small, dark-colored flies resembling tiny mosquitoes. They have long legs and slender bodies. The larvae live in moist soil and feed on organic matter and plant roots, while the adults are mostly a nuisance. Fungus gnat infestations are common in overwatered or poorly drained pots.

Leaf Miners

Leaf miners are the larvae of various insect species, such as flies, moths, and beetles. They create distinct trails or tunnels within leaves as they feed. These trails appear as whitish, winding lines or blotches. Infested leaves may become discolored, dry, or prematurely drop.

Slugs and Snails

Slugs and snails are mollusks that leave behind a telltale slime trail. Slugs have soft, slimy bodies, while snails have a protective shell. They feed on leaves and tender plant parts, leaving irregular holes and chewed edges. They are particularly active during damp or rainy conditions.

How to Keep Pests Out of Gardens

When looking how to keep pests out of gardens, there are several steps you can take including;

  • Maintain Good Garden Hygiene: Keeping your garden clean and tidy is essential for preventing pest infestations. Remove fallen leaves, debris, and weeds regularly, as they can provide shelter and food sources for pests. Dispose of plant residues properly to prevent the buildup of disease and pests.
  • Practice Crop Rotation: Rotate your crops each season to disrupt pest life cycles. This practice helps prevent the buildup of pests that target specific plants. By moving plants to different areas of your garden, you make it harder for pests to locate their preferred hosts.
  • Use Physical Barriers: Physical barriers can be effective in keeping pests away from your plants. Use row covers or mesh to shield plants from flying insects like aphids or cabbage moths.
  • Companion Planting: Companion planting is a technique where specific plants are grown together to enhance growth and deter pests. Some plants naturally repel pests, while others attract beneficial insects that prey on pests. For example, marigolds can repel aphids, while attracting ladybugs, which feed on aphids. A good option is to use these All-In-One Anti-Bug Companion Plant Seeds from Lush & Dew to help rid your garden of plant pests the natural way.
  • Employ Natural Predators: Invite natural predators into your garden to help control pest populations. Ladybugs, lacewings, and praying mantises are beneficial insects that feed on garden pests. You can attract them by planting nectar-rich flowers or providing suitable habitats like insect hotels.
  • Use Organic Pest Control Methods: If pests become problematic, explore organic pest control methods. Options include insecticidal soaps, neem oil, or horticultural oils, which can effectively target specific pests without harming beneficial insects or the environment. Follow product instructions carefully. There are also plants that eat insects known as carnivorous plants.
  • Practice Water Management: Overwatering can create favorable conditions for pests, particularly fungal diseases and root pests like fungus gnats. Water your plants at the base, avoiding wetting the foliage excessively. Ensure proper drainage to prevent waterlogged soil.
  • Regularly Inspect and Monitor Plants: Frequent monitoring of your plants allows early detection of any signs of pest activity. Inspect leaves, stems, and undersides regularly for eggs, larvae, or adult pests. Promptly address any issues you spot to prevent pests from spreading and causing significant damage.
  • Learn Integrated Pest Management (IPM): Integrated Pest Management is a holistic approach to pest control that combines multiple strategies, including cultural, biological, and chemical methods. Educate yourself about IPM principles and apply them accordingly for effective and environmentally friendly pest management.
  • Seek Expert Advice: If you encounter persistent or severe pest problems despite your best efforts, consider seeking advice from local gardening experts, extension services, or master gardeners. They can provide valuable insights and recommend appropriate solutions for your specific situation.

By implementing these practices, you can create an environment that is less attractive to plant pests and more favorable for the health and productivity of your plants. Remember, prevention is key, and a combination of proactive measures will help you maintain a thriving and pest-free garden.
