We have gall wasp in our lemon tree. We’ve been repeatedly cutting it out over the years but it keeps coming back! I just want to let my poor tree grow!! Do those yellow pest strips actually work? Or anything else other than severe pruning?
Keen to hear everyone's tips. Thanks.
I’ve chatted to horticulturists about this problem as we have had difficulties with the wasps too and they recommended the pest strips. They are also inexpensive so certainly worth a try. They are a lot less invasive than harsh pruning.
I am interested to hear other people's experiences.
Citrus Gall Wasp is a big problem in Melbourne (and Australia). They keep coming back because you'll have neighbours somewhere with the same problem - and they may or may not be addressing it.
I'd recommend talking to your neighbours and getting them to talk to their neighbours and so on so you can try and eradicate it from a wider area.
I've given up cutting it out, pruning seemed to be hurting the tree too much and we went years without getting any fruit. The trees seem to cope OK now.
The yellow strips seemed to help a lot for my little trees. I also used a scalpel and chopped off any I saw if it was still a small lump.
Definitely use the strips. You must also cut it out though. If you leave it the new ones hatch and it keeps creating the problem. Need a neighbourhood campaign to really get rid of it.
I've finally got around to getting some strips. Will let you know how I go with them.
Thanks for the advice.
I slice the top of a gall and the eggs die, but that only works if I keep at it. I have never heard of those yellow strips - thanks going to try them.
How's everyones citrus going? I'm perservering with both the yellow strips and cutting it out, but without the heavy pruning of previous years as I want as much fruit and growth as possible. Still an ongoing battle!
