Aphids

general info

About Aphids

Aphids are tiny, soft-bodied garden pests with long, slender mouthparts they use to suck the sweet nectar from nearly every type of plant under the sun. They may be green, brown, yellow, red or black, depending on the species. 
In warm weather, each adult aphid can produce 100 offspring in a single week. It’s easy to understand why aphids are such a problem around the home and garden.


How Aphids Harm Plants

Most healthy plants are able to withstand a few aphids, but a serious infestation can cause major problems for gardeners. Inside the home, aphids can threaten houseplants very quickly.
An infestation of aphids may cause yellowing, curling and distortion of leaves. The tiny pests exude honeydew, a sticky substance that fosters black mold. Aphids are also capable of transmitting harmful diseases from plant to plant.


Signs and Symptoms

Check houseplants and outdoor plants at least once every two weeks. Look closely at the underside of leaves, where aphids tend to gather en masse. If you notice tiny white spots on the leaves and the surface of potting soil, act quickly; those are aphid eggs. 
 

Controlling Aphids: Tips and Tricks

  • Prune affected areas if aphids are limited to a few shoots or leaves.
  • Spray infested plants with an insecticidal soap spray. When used as directed, soap sprays are safe and effective for aphids found outdoors or on houseplants. Spray one leaf first to be sure the soap won’t damage the plant.
  • Stronger aerosol pesticides may be necessary for serious infestations, but before spraying houseplants, ensure the product is approved for indoor use. As an added precaution, spray the plant outdoors and let it dry before bringing it back inside.
  • Because aphids reproduce so prolifically, you may need to treat houseplants several times to gain the upper hand. Use pesticides carefully and only when necessary, as aphids may become resistant. In this case, soap spray is a better choice for outdoor and indoor plants.
