Rosemary beetle is now prevalent in London gardens due to the use of imported nursery stock. If not treated, the beetles can destroy new growth and flowering buds of Rosemary and chew the stems of Lavender leaving not a single flower.
As the growers and nurseries tend to use chemical treatment to hold damage at bay, the pest is difficult to spot initially. However, once the grubs hatch and the adult beetle matures, damage will follow and spread as the beetles breed from spring to autumn. Do not be distracted by the beautiful metallic sheen of this pest, it needs to be eradicated.
