Aphids: The Unwanted Garden Guest

Aphids are one of the most common garden bugs in Australia, and are often found on plants such as roses, lavender, and vegetables. These small, soft-bodied insects feed on plant sap, causing curled or distorted leaves and stunted growth. To identify aphids, look for small, pear-shaped insects with long, slender legs and antennae. They can be found on the underside of leaves, on stems, or on the soil around the base of the plant. Treatment for aphids typically involves spraying with a mild insecticidal soap or neem oil.

Whiteflies are another common garden bug in Australia, and are often found on plants such as tomatoes, peppers, and cucumbers. These small, flying insects feed on plant sap, causing yellowing leaves and stunted growth. To identify whiteflies, look for small, winged insects with a white or yellowish color. They can be found on the underside of leaves, on stems, or on the soil around the base of the plant. Treatment for whiteflies typically involves spraying with a pyrethrin-based insecticide or neem oil.

Spider Mites: The Tiny Terror

Spider mites are tiny, spider-like insects that feed on plant sap, causing yellowing leaves and stunted growth. To identify spider mites, look for small, white or yellowish specks on the underside of leaves. These specks are actually the mites themselves, which are too small to see with the naked eye. Treatment for spider mites typically involves spraying with a mild insecticidal soap or neem oil.

Mealybugs are small, white, cottony insects that feed on plant sap, causing stunted growth and reduced yields. To identify mealybugs, look for small, white, cottony patches on the stems or leaves of your plants. These patches are actually the mealybugs themselves, which are covered in a waxy coating. Treatment for mealybugs typically involves spraying with a mild insecticidal soap or neem oil.

To identify scale insects, look for small, brown or black spots on the stems or leaves of your plants. These spots are actually the scale insects themselves, which are covered in a hard, armored shell.
