Review: Cleared a parasite from banana magnolia shrubs - My banana magnolia tree has the faux scale parasite and this product is clearing it up. More fresh growth and leaves free from parasite. A lot of people online say neem oil but that did not work for this parasite. It did take about 2 good doses. Add a small amount to a decent size spray bottle and spray both downward and upward as the sun starts to set. Don't apply during the heat of the day.

## Questions & Answers

**Q: What time of year should you spray?**
A: This product can be sprayed any time of year. If during the summer an application needs to be made it should be done in early morning or late evening

**Q: Is it also good/use on arborvitae trees (aka emerald green tree)?**
A: Yes. It is good for all trees and shrubs

**Q: What are the ingredients please**
A: I don’t know what the “other ingredients” are, but it’s 80% mineral oil. I expect the “other” stuff is to keep the oil mixed in with the water you dilute it with.

**Q: Does it work against ants?**
A: Not really. There are much more effective ant controls on the market
