Mites feed year-round in greenhouses. Use insecticidal soap or oils to control early-season mite populations. Alternate miticides used later to prevent resistance in the mite population. When immature, these are small, scale-like, and found on the undersurface of leaves. They damage plants by sucking out juices.
Adults are small, white, flying insects.
Cranberry rootworm beetles. They feed at night and hide in litter or under containers during the day. Beetles damage leaves by chewing oval-shaped holes. They are usually associated with container nursery stock in areas with dense shade. Remove ground litter and weeds from the area and reduce shade where possible.
