The range of potted plants is too large to allow treatment of each type individually on this web site. Individual species or varieties may only suffer from one or two of the pests listed below, whilst others will suffer from a wider pest range. There may also be pests, specific to some ornamental plants, which are not listed below. Tolerance of pests may be very low for aesthetic reasons, and biological control agents need to be chosen and used carefully to achieve control.
Note that beneficial mites or insects may require licences or permits for use in some countries, and that some of the species listed below may not therefore be available.
