What is a tree aphid?

Tree aphids (as shown above) are soft-bodied, pear-shaped insects that can be almost any colour. Aphids on tree foliage and shoots feed by sucking fluid from the tree through a slender mouthpart called a proboscis. They feed in clusters, usually on the undersides of leaves near the point where the leaf attaches to the stem, or on tender young shoots and buds. As they feed, they secrete a sticky fluid called honeydew. When enough aphids are feeding on the tree, this honeydew will begin dripping from the leaves.

Tree Diseases Spread by Aphids

Some tree diseases are spread by aphids, especially fungal diseases. Tree disease is much more serious than aphid infestations, and can kill or seriously damage a tree. To prevent the spread of aphid tree disease and avoid needing tree removal, keep the tree as healthy as possible to support its natural defence against disease and control the aphids as much as possible.

Aphid Removal Advice

One of the best ways to treat these infestations is to ask your tree surgeons to prune the young shoots from the tree, eliminating the insects and the cause of the infestation in one go and giving your tree a trim at the same time.
