Aphids

Aphids are sap-sucking insects that feed on many different plants. They are often called greenfly but there are many species that are other colours; yellow, red, even black. They are commonly found on new growth of plants such as buds, and new leaves where it is easier for them to get their hypodermic-like proboscis into the plant to reach the sap. So in spring with lots of new growth on plants, there is often a boom of aphid numbers and their population can rise very quickly, not least because they have some extraordinary habits.

As with all pest control, prevention is better than cure. Pro-active protection of plants from aphids and other sap-sucking insects will protect your plants from loss of vigour due to these pests.

To get rid of aphids follow these steps:

Infestation Control

• Be on the lookout for aphids in spring. They are usually found in areas of soft plant growth.
• If your plants already have an infestation you can squash them between your fingers, but this might be difficult on more than a few buds. Use Kiwicare PLANThealth Spectrum concentrate or Spectrum Plus ready to use to spray the affected parts of the plants. Make sure the undersides of leaves and inside curled leaves are treated.
• For a great natural and BioGro® certified alternative try Organic Insect Control or Organic Super Spraying Oil . Organic Super Spraying Oil suffocates the aphids on contact.

Ongoing Control

• PLANThealth Insect Hit Natural or Spectrum concentrate can also be used to continually protect your plants from aphids once the infestation is under control.

Houseplants

• Use Gro-Sure Houseplant Insect Control Spray.

Control Ants and the Sap Sucking Insects they 'Farm' in Trees, Shrubs and Ornamentals

• Apply LawnPro Protect on the soil around the roots of affected plants. This kills and prevents ants moving up the plants.
