It's important to note that bar soap is made with fat - a food source. If they are hungry enough, they'll eat it.
Please please please, don't rely on anything that claims to be a repellent until you take the time to really seal your rig up. Then use what ever floats your boat. Seal FIRST! Otherwise it's like trying to discourage a thief by leaving a radio on, then going for a vacation with the front door unlocked and wide open.
