How do I deal with aphids?

Aphids are small-bodied insects and tend to have a pear shaped body and long legs. With their mouth, they pierce the tender part of plans (stems and leaves) to suck the sap out for food. If you have a small population of them, it’s usually not a problem because they provide a food source to beneficial predators. However, when the population gets out of control, wide-spread damage to your garden can occur.

Prevention practices

  • Provide natural predators such as ladybugs, brown and green lacewings, and hoverflies by planting a diverse collection of native plant species such as dill, parsley, and marigolds.
  • Some ants will farm aphids as food. To reduce the population of aphids, lay down sticky bands to prevent the ants from cultivating aphids.

Non-chemical and mechanical techniques

  • Trim or prune the areas where the aphids are gathering and dispose of them.
  • Grow vegetable/fruit seedlings in a protective area until they are older and more tolerant of aphid feeding.
  • Spread silver colored reflective mulch or slow releasing nitrogen much to dissuade  aphids.
  • Knock off aphids with a strong spray of water. Do this earlier in the day so the plants have time to dry and reduce the risk of a fungal disease.
