Thank you so much Liriodendron. Sadly I think you're right. We found an adult on our almost dead azalea last night after reading your post.
We've drenched and drenched over the past couple of years and it's not cleared them so I've ordered some nematodes and traps for the adults. Only hope my beautiful rhody can be saved.
Out of interest which plants are most susceptible? I have my rhodies and azaleas in pots. My borders with petunias and violas have been untouched (except by slug). Think they've also had my hydrangea.
I also have roses in pots. Should I apply nematodes to everything or target the most susceptible plants?
