Welcome to the GardenAction forum. Feel free to post a message.
I have noticed that my basil is covered with tiny, tiny fly like things, Whenever you touch the leaves, they fly off only to return. I have also seen strands of white almost like spider web. They are destrying my herbs. What can I do?
The fact you mention 'destroying' and strands of web suggests Red Spider mite to me!

But the flying away and returning aspect suggests aphids.

What colour are the flies?
