When you suspect a trap, you can put the end of your 11-foot pole through that hole in the wall instead of reaching in with your hand. The 11-foot pole works as a staff that deals 1d6+strength magic bludgeoning with reach.

Proficiency with a Staff allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Notes: Damage: Bludgeoning, Versatile
