Because this ant killer is poisonous to humans, great care should be taken when you open the container.  A customer explains how easy it can be to mess up and harm another individual, “This is a very effective poison but be careful!  This product is a very fine powder in a soft-sided container.  It is too easy to shoot this powder out in a poisonous cloud when opening the container.  Hold the container as far from you as you can while unscrewing the cap.  Do not squeeze the container while opening it.  Both of mine arrived with the inner seal covering the shaker top displaced.  Don’t assume yours is sealed under the cap or you will blast this poison onto yourself or bystanders.”
