Gall Wasp Treatment: Save Your Citrus Trees!
Have you had a close look at your citrus trees lately? If not, check them against these photos…
Are there swollen looking lumps appearing on your tree at the end of the branches?


These ugly, swollen lumps are “galls” caused by the Gall Wasp. Their eggs are laid in the branches of your trees from about mid-September to mid-October.
They are very destructive and unfortunately, grow like crazy!
We can fix this problem with our Citrus Gall Wasp Management Program, a comprehensive gall wasp treatment plan.
You don’t want this thing to get out of hand and kill your trees. Imagine having to start over again!
A Gall Wasp infestation destroys tree frames, one-by-one, resulting in poor fruiting and overall, bad tree health. And it doesn’t go away in nature.
Other trees in the neighbourhood, if not affected already, soon will be if this problem is not stopped, fast.
And the cooler winter months are the best time to get this sorted. Now is the perfect time.
Gall Wasp Treatment
If you want to continue growing citrus trees, here’s what you need to do…
- Identify if the problem is evident in your tree(s) now
- For small trees, remove/prune all galls; it’s easy, you just prune off all affected branches.
- Same for larger trees but the entire canopies must also be dealt with if affected; you may need professional help with this one
- Dispose of all infected foliage in the general rubbish bin, NOT in your green waste; but, burn it if you are able to
- Spray the tree with Kaolin clay around the beginning of September…
* The gritty particles act as a deterrent so wasps are less likely to lay eggs
* It offers an added benefit of UV protection to sensitive bark exposed to sun from pruning.
- Regular checks for small outbreaks will be important (some do get through the ‘wall of defence’ because they weren’t swollen at the time of pruning)
- Small amounts of fertiliser should be added to the soil regularly after pruning, to promote new growth and improve the general health of the tree.
The Result of Neglect:

It’s beyond help and needs to be removed.
