Are Grants Ant Stakes environmentally safe?
Yes, if they are used judiciously. Don’t use them outside where rain or irrigation water can wash the bait into the soil. Remove ant stakes after ant trails disappear. Store in original container inside a plastic bag. They will last for over 15 years. If used this way, only a very small amount of arsenic will get into the environment. Q: I heard that boric acid has arsenic in it, so it isn’t safe. A: It is true that boric acid has traces of arsenic in it because boric acid is mined from the earth and things mined from the earth may have traces of arsenic. However, you would die from the boric acid long before the arsenic affected you, and you would have to inhale or eat a large quantity of boric acid over a long period of time for it to be fatal.
