## Description

Fertilome Spinosad Bagworm, Tent Caterpillar and Chewing Insect Control Oil, Quart

Review: Saved my boxwoods! - Worms/moths were having a field day with our boxwoods. This did the trick!
Review: Good stuff - This worked well as a preventative but not a solution. A bunch of bagworms took up residence on 1 of our arborvitae trees and we have another one less than 10’ away. They were already heavy on the first one and we sprayed both. The one already infested is dead, I guess the infestation was too much cause it didn’t bounce back and kept getting worse. We sprayed the other one as a preventative to keep it from spreading and that one is still alive and healthy. So use it before you have an issue otherwise it’s useless.

## Questions & Answers

**Q: How do you apply this? Would I need to buy a sprayer separately?**
A: Yes, you need a sprayer. This is concentrated so you need to mix with water. I mix in a 1 gallon sprayer. Follow the mixing and spraying instructions on the bottle.

**Q: Do you have to spray the entire shrub or just around the base?**
A: I sprayed the entire shrub and whatever fell on the ground and it did kill the bag worms I was amazed but yes I sprayed the whole bush very heavily

**Q: Is this systemic, or spray on?**
A: This is spray on.

**Q: Is this a concentration? How much of this to add to a gallon of water?**
A: It is concentrated. 2 ounces per gallon. Or a little more depending on what you are spraying for. Mine was a 32 ounce bottle
