Controlling Aphids on English Ivy

Diagnosis

Sticky leaves, clusters of tiny grey bugs on new growth, and leaf curling on a mature ivy wall indicate aphids. They feed on tender new leaves, excreting honeydew.

Treatment

Rose insecticide spray (check label for aphids) works well. Mix concentrate for large areas. Spray both leaf surfaces thoroughly. Repeat as needed. Aphids target new growth; older leaves are less affected.

Recovery

Ivy is resilient. Once aphids are controlled, new growth will be clean. Prune heavily damaged sections if desired.
