over 20 years. It's definitely effective, but, I've been told if not used properly can be very toxic. My father-in-law used to spray it in the house like it was 409. And, my mother-in-law would wipe the counter tops down with a sponge after he sprayed. She did get very ill shortly thereafter. Some of us in the family think the chlordane was a contributing factor. You have to use and follow the directions exactly. Glad it works for you....got bit by a fire ant years ago when visiting my Dad in Jacksonville. Be careful with the chlordane. |
