Review: Lots of uses - I love this product. I spray around the perimeter of my house every six months. BUT HERE IS WHAT SURPRISED ME. I was plagued with mealy bugs on my olive trees and tried all the sprays from the garden stores. Nothing worked. So I tried using Home Defense as it said it was safe. It IS safe on plants and killed all the tree bugs in just one application.
Review: Worked fine - Worked great on my small vegetable and flower garden. I keep spraying it every 4 weeks and don't see the aphids and other pests anymore. Good product

## Questions & Answers

**Q: how high will the spray reach?**
A: Pretty darn high!  It mainly depends on the strength of the water from the hose.  I use this to treat a bush that looms over my roof.

**Q: Does this contain neem oil?**
A: The label states “Active ingredients: Mineral Oil 98.8%. Other Ingredients 1.2%”. Hope this helps.

**Q: Will this kill mosquitoes, flies and bees?**
A: I doubt it.  Its for little things that live on the plants, like aphids and mites.

**Q: will this kill white flies without hurting my "organic" house plant?**
A: I had a ridicously large infestation of white flies last summer. I tried everything and this was the only thing that worked. I highly recommend it!
