I too have wondered where pests suddenly appear from - lily beetles for
instance. They seem to home in from miles away!

I remember hearing Bob Flowerdew say on GQT that carrot fly can home
in on the scent of carrots from up to 7 miles away. They fly. Surely
spider mite only crawl? If so where have they crawled from is the
mystery to me. As I said, I have not seen any on my plants for some
years and have not bought any new plants.
I must look at the recommended sites.
Thanks all!
