Underside Of Lemon Tree Leaves Have Bug That Looks Like Little Brown Connected Circles Up And Down Center

Question From: WASHINGTON
Q: I have a small lemon tree sitting on my patio. I notice that the underside of the leaves have some kind of bug--little brown circles, almost look like their connected, running up and down the center of the leaves. What is it, and how do I get rid of them? I live in Tacoma, WA if you need to know that.

A: Take samples of damaged leaves to a good independent garden center or nursery for an accurate ID and methods of control. Best And Happy Yardening, Nancy
