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.

and when the surrounding fields are full of carrots, why do they pick
on our tiny plot of carrots?

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 think the answer is blowing in the wind.
