Be sure to buy plain sponges without cleanser or lotion in them. Ant control, habitat manipulation, and pesticide management are the key natural enemy conservation strategies. Pesticides to avoid include carbamates (carbaryl* or Sevin), nonsystemic organophosphates (malathion), and pyrethroids (bifenthrin, fluvalinate, permethrin). There are several things you can do to prevent populations of Hard Scales Insects building up to damaging levels (seeHow To Prevent Scale Insects Appearing). The active ingredients of pyrethroid insecticides all end with "-thrin.". You may effectively address minor scale infestation on small ficus trees by rubbing each scale with a cotton swab soaked with rubbing alcohol. Scales are preyed upon by small parasitic wasps and many predators, including certain beetles, bugs, lacewings, and mites. NC State University and NC In Texas, the Florida wax scale has two fairly distinct generations per year (eggs hatching in late April through May and again in late July through August), although some eggs can hatch during other months. Avoid methods that cause large wounds, such as implants placed in holes drilled in trunks. The life cycle takes about eight weeks over summer and there are several overlapping generations per year.

This can be quite laborious in an outdoor garden, however, so you can also fill a garden sprayer or spray bottle with a mix containing one part rubbing alcohol to seven parts water.

Adult female White Louse Scales are about 2 mm long, dark brown and mussel-shaped. Carefully follow label directions. Female nymphs are smaller versions of adult females. Publ. Crawlers settle down and begin feeding within a day or two after emergence. This application will smother the scale before the insects have a chance to form their protective coating. They then settle down to feed either on leaves, twigs or small branches. Prune off any ficus branches that are touching the ground, another plant or a structure that could provide a bridge for the ants. Underneath the wax cap, the body of the scale is red.

Repetition and consistency are the key to success. Wash dust off of ficus tree foliage with a strong spray of water whenever a large amount of dust accumulates on the ficus leaves during the growing season, as dust disrupts natural predator activity. Do not implant or inject into roots or trunks more than once a year. If a spring or summer foliar insecticide application is planned, unless another time is recommended for that species, spray after crawler production (abundance in traps) has peaked and definitely begun to decline, which is soon after most crawlers have settled. Crawlers go through several moults under scale covers, before becoming adults. Dispose of the pruned stems immediately. Scale insects typically adhere to the stems, branches, and sometimes the leaves of plants to feed on sap, and they have a shell-like bump appearance, which sometimes causes them to be mistaken for a fungal or bacterial disease. Botany (Taxonomy, Nomenclature and Morphology). Repeat every two to three days until the problem insects are eradicated. However, some of the scales colonize the underside of leaves, on twigs and branches, where they are more protected. Inspect plants to determine whether female scales, nymphs, honeydew, sooty mold, or ants and other pests are present. If you need to control scale on hedges or larger ornamental plants, stone fruit, citrus, or grapes, then useYates PestOil Concentrate. The importance of infestations depends on the scale species, the plant species and cultivar, environmental factors, and natural enemies. Nymphs are partially or nearly covered with a pattern of pure white conical wax plates that show up later as buttons on mature females. After these scales have completely covered their bodies with wax (probably early summer), they are likely to be very difficult to control with sprays. Certain plants may be sensitive to oil-based sprays, so do a test spray on a small inconspicuous area and observe over the next couple of days to see if there is a reaction. That sticky stuff on the leaves is the secretion from the insect. After settling, nymphs insert their thread-like mouthparts into the plant and begin to secrete wax in tufts around the body that give them a star-like appearance. Apart from biological control (seeNatural Enemies), the mainstay of Scale Insect control is the application of horticultural oils. Oakland: Univ. Sorry to hear about your long-lived ficus tree.
