The presence of large swellings or bulges on the branches of the tree indicates that Gall Wasp is active. The wasp emerges from the gall from August to November. The wasp lives for 3 to 4 days and lays its eggs in the branches of the citrus tree. It is the trees 'reaction' to this egg-laying which produces the next years, gall wasp. The best and most effective control is cutting off the swollen branches and burning them to completely destroy the Gall Wasp cycle. Spraying is often ineffective.

The presence of the Leaf Miner insect is characterized by silver trails just under the surface of the leaf on new growth resulting in curled and deformed leaves. Control is more important on a young tree as leaf miner will stunt the trees growth if left unattended. Spray oils can be an effective treatment, many oil sprays are organic and quite safe. Consult your gardening centre for product advice in controlling leaf miner.
