All about the health of my ivy

The weaver spider mite (Tetranychus urticae)

Ivy is relatively rarely attacked by parasites. In addition, in the event of an infestation, it is generally sufficiently resistant to avoid irreversible damage. Among these potential pests is the spider mite.

This red, half-millimeter mite is particularly dangerous in greenhouses. It likes dryness. It weaves fine webs and discolors the leaves by stinging the leaf blade.

As a preventative measure, it is recommended to maintain a humid and well-ventilated environment. In the event of an infestation, perform a copious drenching on both sides of the leaves and repeat for several days. Treatment with an acaricidal soap or with Neem oil may be necessary if the infestation persists.

Regular monitoring allows the attack to be detected as early as possible, which makes the treatment much more effective.
