Frequently Asked Questions

Are aphids harmful to plants?

Yes. They drain sap, which stunts growth and distorts new leaves, and they excrete a sticky honeydew that encourages sooty mould. Many species also carry plant viruses from one host to another, which is often the more serious problem.

How do you get rid of aphids naturally?

A strong jet of water knocks most of them off, and repeating it every few days keeps numbers down. Encouraging ladybirds, lacewings and hoverflies gives you lasting control, and insecticidal soap handles heavy infestations without wiping out those predators.

What is the difference between an aphid and greenfly?

Greenfly is a common British name for the green-coloured aphids found on roses and vegetables, and blackfly for the dark ones on beans. Both are aphids; the everyday names simply describe colour rather than a separate kind of insect.
