Unlike dormant oils these oils are highly refined and can be applied to plants in foliage without damage under proper conditions. Follow label directions to avoid damage to some plants that may be sensitive. Superior oils are also considered not toxic and are gentle on beneficial insects. When spraying indoors protect surfaces which may be damaged by an oil residue. Use chemical insecticides.
Many insecticides registered for use indoors are available.
A very safe product made from the seeds of a tropical tree is Neem. Margosan-O. Sprays containing pyrethrin, another plant derived insecticide, are also effective and more benign than other chemical pesticides. Follow label directions and, if possible, spray out of doors or in a garage, weather permitting. To limit future problems, inspect plants regularly. With regular inspection pest problems can be caught when just beginning and control is easier.
