Wouldn't make a huge difference - the aphids fly a respectable distance.


Read an article recently which said that scientists have found aphids being
taken to the upper atmosphere by thermals freezing and being blown a long
way before dropping down, thawing and going about their business.
Frightening!
Hope it's not true.
