What’s that Lump?

Citrus Gall Wasp is a tiny little black insect, Bruchophagus fellis, if you wish to be formal, and it is responsible for infesting, disfiguring, and creating weakness and illness to our loved domestic Citrus trees.

All Citrus is prone to infestation however the Gall Wasp tends to favour Lemon and Grapefruit trees.

It is about this time September, October that the little eggs laid by the wasp are hatching and feeding inside the stems of the citrus tree, they will do this right through the year and they emerge in the early Spring to begin the cycle over again.

There are several effective control methods and they are chemical free, however they do involve you, and good tree management and care.
The rise of infestation and insect numbers of this destructive insect is largely due to lack of tree care, neglected citrus are prone to attack and become safe havens for the wasp to breed and spread.

  • PEST OIL – Regular spraying with pest oil will considerably reduce the impact of Gall Wasp, pest oil is a really useful for general tree care and protecting your Citrus from many other pesties….
  • CUT AND BURN - Prune and cut out the gall damaged stems, it is vital that the stems are burn’t to completely destroy the pest.
  • INSECTRAP – These are very effective natural traps that you hang in the citrus tree the wasps are attracted to and stick to the solution within the trap and it’s “party over”!

Citrus Trees are just like us – the healthier we are, makes us more resistant to disease and infection, and the more bountiful and vital we become!
