Answer to Question 1

Because they are protected with a wax-like coating that keeps contact pesticides from reaching them

Answer to Question 2

The tops of the leaves will have a tiny white pinprick pattern. Under the leaves you will be able to see the mites with a magnifying glass. Webs also may be present under the leaves.
