Is this Scale on my Holly shrub? Picture
Can someone tell me what this is & what to do to get rid of it? It's all over the leaves & stems of my 5 Holly shrubs. When I was taking the pic I noticed a tiny red spider-like bug crawling on one of the leaves. There's also a small web. We've been trying to get rid of this infestation for the past 3 weeks. We've used Bayer Tree & Shrub Protect & Feed around each shrub, & have been spraying with fungicide 3 in 1 spray. The shrub now has some new growth, but the white bumps are still there.
Any suggestions for successfully getting rid of this, or should I just dig them up & replace? Thank you in advance for any advice!
I tried to get a close up but it's a little blurry.
