Citrus borer (forum)

Vanessa starts with ...
We have some citrus that are badly affected by borers. Is there any organic control known for these pests and are there any earlier warning signs than a branch dying off? How do they breed and will leaving a nearby tree untreated increase their population? Are there any varieties of citrus less susceptible to boreres.
We also have some mature citrus that are now shaded out by other trees. Is it worth moving them and if so do we cut them right back before moving them and in what season would this activity be most suitable?
Thanks for the opportunity to field some questions

you can't find every borer.

i beleive diff Citrus are different in their attrraction but what's what, no one knows

pyrethrum works fine squirted down their hole but I wonder if eucalyptus oil or hot chili wouldn't work as well?

I have been waiting for my Citrus to be shaded out to test for fruit quality. so far so good.

I wouldn't move them.i'd buy more and yes cut back b4 moving.

Borers in citrus are a big problem. Problem seems worse in damp areas. Hard to spot until its too late. If you see the sawdust, shove a bit on naphthalene (moth repellent) up the hole and seal with tar. I've been told opening the centre of the tree helps and we are starting to try that. Some species are definitely more resistant.
