The Carnation Tortrix Moth is an insect belonging to the insect family named the Tortrix Moths (Tortricidae). The caterpillars bind the leaves of the infested plant using their silk to build a protective barrier which conceals them while they feed. The leaves ultimately dry up and turn brown. They'll bore into flower buds and damage fruits of some plants, too. There have been a few recordings of this moth in South Africa, however, they are scarce.

Biological treatment

It's been advised that plants can tolerate light infestations. By squeezing bound leaves (or stepping on them), you can squash the caterpillars and pupae.

Chemical treatment

For heavier infestations, control may be achieved with pyrethroid sprays such as deltamethrin and fenvalerate. If a chemical option is sought, check with your local garden centre and please take care to follow the manufacturers' instructions. Check with your local regulating body for guidance on active ingredients and their authorisation for use. Plants that are in flower should never be sprayed due to the danger they pose to pollinators.

Attracts

There are about 100 species that this moth will readily use as a host, but Dianthus spp. seems to be affected most severely.
