How to rid my laundry room of musky smell due to pipes backing up from spare bathroom and washing machine

Pipes in the spare bathroom and the laundry room all backup to the same pipes. Bathroom backup due to some one putting items in the toilet that shouldn't gone in. Not knowing this I ran the washer and hence all the water from the washer then backup the pipes and now have water all in my spare bathroom floor but also my laundry room floor. All the water was vacuum out and toilet and pipes cleared; but now my laundry room has a musky smell.

OK - presumably you have solved the drain blockage issue with routing or jetting or snaking. Couple of related questions with answers about that if not:

Since the bathroom and laundry room flooded, the bottom of the walls would have gotten wet - possibly as much as 6-12 inches up into the walls if the water sat in there long enough to wick up into them, so that may be where your smell is from. Sometimes just disinfecting (bleach) the floor and base of the walls and then running a large fan in the room for a couple of days to let it evaporate will work, especially if it was basically all washing machine water, not sewage that backed up.

Otherwise, you need to get a Smoke and Water Damage contractor in - depending on what they find by opening a small hole in the wall a place or two to inspect, may say they can handle it with small holes in the wall and blower unit bglowing through flesx hose into the holes to dry them out (commonly 1-2 about 3-4" holes per stud bay), or may say you need to pull the bottom foot or two of drywall, replace wet insulation (if any) and then re-drywall and paint after it has been disinfected and dried out.

If you have a flooring product in there (something other than concrete or grouted-down tile or stone over concrete) then you may be smelling mold/incipient rot in the subflooring (if wood subfloor) or the flooring product itself. Hard surface flooring like tile or stone can commonly be disinfected and dried out - though if on wood subfloor generally have to dry out from underneath through access holes in the ceiling below it.

Generally, any flooring product (carpet, laminate, wood plank, linoleum, etc) needs to be pulled up and scrapped after flooding with water from a sewer, because the result will rarely be good if just dried out with big fans like you can sometimes do with clean water flooding.

Of course, if going with a contractor for this, likely going to be economic (unless you have a real high deductible) to file a homeowner's insurance claim on it because you are commonly talking $1000 minimum or so for remediation - more if replacing flooring is needed. The insurance company can also commonly help steer you to remediation companies whjich they have had decent experiences with.
