Scale insects

<< < (2/2)

We have some huge orange trees here which have a scale issue - no idea how to cope with a 20+ foot tall tree with are covered in scale.  There is a spray here but you need a license for it..

I remember reading somewhere that methylated spirits cut through the scales protected coat but I haven’t tried it myself....I get them on my indoor orchids and pick them off by hand and immerse the whole plant in mild washing up liquid every so often....bit difficult to do to a tree though!

saddad:
A lot of excellent advice there, thank you all. I would never use a persistent insecticide on anything I want to eat... part of the reason for growing my own fruit and veg! I agree with Alice in Wonderland...." If you drink too much from a bottle marked poison, it's almost certain to disagree with you, sooner or later..."

You just need a large enough washing up bowl - it's a question of scale.

(I'll see myself out.)
