## Questions & Answers

**Q: This says weed and grass killer. Is this safe around sedges?**
A: My experience is that it is safe around hedges. For me it has only killed what I’ve directly sprayed it on

**Q: Is this product pet friendly**
A: I honestly wouldnt. This is a lot harsher of a chemical than glyphosate which is proven to be safe and used in zoos and nature preserves. Diquat is measured in ppm to kill aquatic weeds if that gives you an idea how powerful this stuff is.

**Q: Do I have to mix it or can I just pour it?**
A: Hi Nydeeyah, thank you for the inquiry regarding our Spectracide Weed & Grass Killer Concentrate. This product needs to be mixed water per the label directions.
