Adults congregate on the newly developing leaves to lay their eggs. Orthene is one of the few products specifically labeled for this purpose. Reducing fall adult infestations Spraying infested exterior surfaces, such as window screens, shutters, and sides of buildings where the psyllids are found may provide some temporary reduction in numbers. There is not a good solution to this problem as it occurs during the fall. The applications should be reapplied after a few days to maintain control.
Indoor control is more restrictive.
An example would be one of the natural or synthetic pyrethroids. Direct the spray to the areas of the house where the adults are observed. Often the simplest answer is to plug up cracks and crevices to prevent the insects from gaining entry. Windows and doors must be kept closed during the period when the adults are seeking hibernation sites. A vacuum cleaner is helpful in sucking up those that have gotten inside.
