You can deactivate beartraps by kicking them, or picking them up whilst levitating, however, picking them up has a chance of getting a limb caught.

Mines are generally found active in GC, and unactive ones can sometime be found in the UT. Landmines are deadly to an early IVAN character, and stepping on one during the early stages of the game usually results in death. To be safe, a ring or cloak of fire resistance will help in preventing a death by landmine, as will a ring of searching, which will detect the mine before you step on it. Currently there is no known way to deactivate mines, but you can destroy them. Praying to silva, zapping a wand of fireballs, using the holy banana or getting a monster to step on it are a few ways to destroy mines whilst keeping safely out of range of the explosion. Mines also come in a bigger variant, the "big mine". These are much more deadly than the standard mine and have a larger blast radius.
