## 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!
