Aphids

Aphidoidea spp.

Plant aphids, Plant lice

Aphids produce large amounts of honeydew. This sticky fluid drips on plants and attracts ants and can also promote sooty mold growth on leaves.

Aphids are a source of food for especially ladybugs and lacewings.

One of the most common garden pests, these small sap-sucking insects are often seen feeding in clusters on new plant growth. There are over 4000 species worldwide and in low to moderate numbers, they are generally not too harmful to plants. However, a general decline in plant vigour will be noticed with a substantial infestation.

Biological treatment

Natural predators include ladybirds, wasps and lacewings. Aphids can also be treated with a strong jet of water to dislodge them from the plant or a light, soapy mixture applied to the plant or even just squashing them. Remember to get rid of ants first in order to get rid of aphids. Neem oil or Ludwig's organic insecticide will also do the job!

Chemical treatment

Avoid using chemical treatment as aphids are food to other beneficial insects and there are more than enough biological ways to get rid of them.
