## 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.

A: Not really. There are much more effective ant controls on the market

### ⭐⭐⭐⭐⭐ Monterey Horticultural Oil Is Easy To Mix And Apply!
*by B***N on December 27, 2025*

Monterey Horticultural Oil is extremely easy to use and apply with a sprayer. I use a 2 gallon sprayer. Spray when the outside temperature is AT LEAST 41 degrees Fahrenheit. Here on Long Island, I’ve sprayed my Peach, Nectarine and Apple trees three times so far. We have had more rain than typical, so I’ll spray at least two more times before Spring time. I combine this product with Monterey Liqui-Cop and a touch of dish soap. Make sure you apply a little extra solution to the “inside elbows” AND the bottoms of the branches! I believe I should realize a very good crop in 2026!
