Spraying your plants with horticultural oil is effective in late spring just before the leaves unfurl. Drees, B. M. and J. While there can be some success in using systemic insecticides that include compounds known as neonicotinoids (acetamiprid, dinotefuran, imidacloprid, and thiamethoxam), these pesticides are now known to be a serious problem for honey bees and other pollinators. Scales are sucking insects that insert their tiny, strawlike mouthparts into bark, fruit, or leaves, mostly on trees and shrubs and other perennial plants. After the insects have died, you can hose them off as well as any sooty mould they may have promoted. Soft Brown Scale camellia, citrus, daphne, ferns, fig, oleander, orchids, palms, passionfruit and peach. Keep the plant well away from other plants until the problem is eradicated.

Ant control, habitat manipulation, and pesticide management are the key natural enemy conservation strategies. If hollies are selected for planting, inspect plants thoroughly to avoid purchasing already-infested plants. Planting a variety of fragrant, flowering ornamental plants and herbs near the ficus helps to attract beneficial scale predators to the area. If the scale produces honeydew, this sticky excrement, sooty mold, and the ants attracted to honeydew can annoy people even when scales are not harming the plant.

Infected fruit are characterized by a soft rot and premature dropping of the fruit. Before applying insecticide, make sure plants are receiving appropriate cultural care and take steps to conserve natural enemies. Tape traps for crawlers and honeydew monitoring are useful in certain situations for determining the need and best timing for pesticide application. First stage (instar) nymphs, called crawlers (Fig. Do not compost infected plant material; it is best to bag it up and throw it in the trash or burn it safely. We have found that Indian wax scale immatures are highly susceptible to Sevin insecticide sprays as well as pyrethroid sprays. Only apply insecticidal soaps to plants that are well hydrated or you can risk damaging them.

This is a huge tree growing to 60 feet tall and 60 to 100 feet wide. Scale Insects on Shade Trees and Shrubs. Each instar can change greatly as it ages, so many scales appear to have more than two growth stages. If most or all of the scales inspected are dead or being parasitized, additional control is generally not warranted and the ficus will recover with good cultural care. Carefully follow label directions. Pest Notes: Ants. Avoid creating dust because it interferes with natural enemies. For example, acetamiprid (Ortho Flower, Fruit & Vegetable Insect Killer) controls soft scales but is not very effective on armored scales and can only be applied by spraying foliage. A member of the soft or unarmored scale family, mealybugs are a widespread garden pest and somewhat larger than most scale insects, making them easier to identify as an insect rather than disease.
