Pests that suck: Cypress aphid on conifers

The Cypress aphid is a sap-sucking pest that secretes poison into its host plant. Cypress aphids are 1.8 —1.9 mm long and yellowish-brown in colour, with a rich coating of tiny hairs causing them to seem greyish. A black stripe runs down either side of the upper body, especially near the head. They are difficult to see since their colour resembles the bark and they might be wingless or winged.

You’ll be able to identify the first main symptoms of Cypress aphid on your conifer as honeydew (a sticky substance found on the plant or leaves). This then not only attracts ants but also leads to sooty mould and then eventual conifer dieback.

Treat Cypress aphid as an inevitable

These pests attack in clustered colonies on the weakest part of the plant like young stems, leaves and buds. Conifer damage from Cypress aphid occurs in all regions – meaning care and preventative measures need to be taken on every conifer. These pests are prominent in winter, though you are likely to only see the effects between late spring and early summer. However, by the time these warmer seasons arrive, it is too late to take action. Once the tree goes brown you cannot recover it.

Unfortunately, you cannot snip off the dead or infected parts of the tree as a preventative measure. We recommend you use insecticides throughout winter for aphid damage prevention.
