Several foliar sprays applied in 7 to 10 day intervals, or as directed on the products label, may be necessary to provide protection of new foliage through the period of egg hatch, particularly when using insecticide products with little or no residual activity such as insecticidal soap or horticultural oil. Soft Scale Insects, Cottony Cushion Scale and Gumtree Scale all produce honeydew, which is a liquid of concentrated plant sugars they excrete. You will need to be extremely diligent about controlling or removing scale when it infests indoor plants.

Properly applied, one application of an effective product may provide season-long control. After completing the larval stage and pupating, the emerging adult of internal parasites typically leaves a round exit hole in the scale it killed. Because ants attack and feed on scale parasites and predators, control ants if they are tending scales. Honeydew also attracts ants that protect the Scale Insects from being attacked by predators and parasites, in return for a feed of the honeydew. Please help me save this tree.

Grow a variety of flowering plants to help attract and support natural enemies. Apply with a spray bottle or garden sprayer until all the leaves are dripping. For species with multiple generations, all scale life stages may be present throughout the year in areas with mild winters. Trace back trail-making ants to locate colonies of the honeydew-producing insects. No. At maturity, adult females produce eggs that are usually hidden under their bodies, although some species secrete their eggs externally under prominent cottony or waxy covers. Change the tapes at weekly intervals. I have a 35 year old indoor ficus benjamina tree, about 8 feet tall. People grow too, and the best bit is that they don't realise it's happening. Honeydew monitoring is useful where there is a low tolerance for dripping honeydew, when managing many trees, such as along city streets or in parks, and on tall trees where the honeydew-producing insects may be located too high to easily observe. This will force ants to climb the ficus trunk and get stuck in the sticky material. B. and M. L. Williams. Repetition and consistency are the key to success.

Scale insects can infest and damage many of the plants we grow in our landscapes and indoors. Systemic insecticides generally do not eliminate all scales located on branches or twigs, so the addition of foliar treatments may be necessary to eliminate the whole population. I have been fighting scale for the last 6 months by severely trimming the tree and applying systemic granules and spraying each week with organic insect spray. Boric acid, fipronil, and hydramethylnon are examples of insecticides used in ant baits. It's important to treat the entire plant, as scale can be present on stems, the undersides of leaves, and along the base of the plant. Neem oil, or any pesticides containing azadirachtin, a key ingredient in neem oil, offer excellent protection against scale, and also will kill the established insectsnot just the larva. Food Agric. Certain scale problems on large plants and hosts especially sensitive to scale damage may warrant the application of a systemic insecticide. The actual insect body is underneath the cover; if you remove the cover, the insect body will remain on the plant. The importance of infestations depends on the scale species, the plant species and cultivar, environmental factors, and natural enemies. 2) are oval and reddish-orange in color, and fill the cavity underneath the bodies of dead or mature adult female scales. When infested plants are to be preserved, control should begin with pruning away and discarding heavily infested foliage. Oakland: Univ.

Gardens, Landscapes, and Turf > To know how and when to effectively make an application, learn more about the available insecticides and the biology of your pest species. Consider rotating work among several tools and using a freshly disinfected tool while the most recently used tools are being soaked in disinfectant. Foliar treatments are best applied after the crawler stage hatches from eggs and begins to settle on new foliage. Insecticidal soaps can be used to kill scale at the larval stage, but they are not very effective once the insects are anchored and feeding under their protective shells. Inspect plants to determine whether female scales, nymphs, honeydew, sooty mold, or ants and other pests are present. Any suggestions for treatment if this on a massive tree? 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.
