Bayer Advanced 12 Month Tree and Shrub Protect and Feed II application timing can vary depending on the type of insect you are using to treat/prevent with it. Please contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region for when the target pest is active.

Bayer Advanced 12 Month Tree and Shrub Protect and Feed II Granules is labeled for scales in general but is not labeled for Euonymus scale specifically. If scale is already present a systemic application may not work quick enough to provide control and stop damage, so a foliar treatment with a product like Talstar P or a product containing neem like Triple Action would be needed.
