You'd be much better served to set your traps and let them soak overnight. A 3 hour soak wont likely result in 3# of mud bugs, even if the area is absolutely loaded with them. It takes a while for the scent to disperse enough for them to pick up on it, then follow the scent to the trap, then find their way inside. Depending on the type of trap, once their in, they'll not get out. Let your traps work for you.
