JACKSON, Wyo. (AP) — There is no discussion in Wyoming about banning a device designed to kill coyotes by spraying cyanide when triggered.

Officials say at any given time there are about 300 cyanide-propelling M-44s protruding from the ground in Wyoming.

A national debate about the predator-killing device is unfolding in the wake of a hospitalized teenager and three dogs and a wolf that have been killed recently in Wyoming, Idaho and Oregon.

The U.S. Department of Agriculture's Wildlife Services division announced it would discontinue using the device in Idaho.

But Kent Drake of the Wyoming Department of Agriculture says there has been no discussion about banning M-44s in Wyoming.

Lisa Robertson of the animal rights advocacy group Wyoming Untrapped says M-44s should be banned.
