We examined a coyote that had been killed 26 hours earlier and stored in subfreezing temperatures. We found most lice still alive on the partially frozen carcass. Cold temperatures apparently do not quickly kill lice. Also, we may have witnessed the death of wolves caused in part by the infestation. Two younger wolves disappeared from the Montana Creek pack right after extended -40F temperatures in the Talkeetna area.
Infested adults tend to lose less hair than juveniles and are probably less prone to exposure.
