Hey jhef:
We've gone back to new bamboo condos the next day and caught fish on them. It will depend on how much other cover there is available and whether or not the fish are on the move.
If there is a lot of cover and they are hunkered down with everything they need they may not find it right away but if either the lake level or water temperature are rising or falling they will be looking for a new place to hang out and will get on it pretty quick.
