I've sprayed it multiple times with heavy duty vinegar to help cut it down, but of course it's continually being fed water. 

New paint, new carpet, new laminate, pressure washing, landscaping, window repairs, fixture updates, sprayed for pests and did electrical repairs.

If the cabinets are in good shape under the grime, give them a really good cleaning and then have the doors sprayed the colour of your choice to freshen them up and add new hardware. 

Problems:1) The sheetrock guy sprayed texture all over the stairs because he didn't cover them.

I hang out with the hose “watering” then accidentally spray them when they walk out and try to get in their car.

Once excavated, new drain tile can be installed, a water-proof membrane can be installed against the wall, and the open space can be back-filled with stone - that's how they build it new today (though sometimes they use a spray sealer instead of a membrane).

The rodents are are territorial and are leaving their odors of familiarity and do return.They put in a sonic anti rodent contoler in the engine, sprayed strong mint, chili spray, mothballs, set traps To no avail.A landlords lackadaisical attitude can cost you a good tenant with lots of repairs and damage.

As soon as the contractor sprayed it, the bees came out and died.

I told them to clean and told them to spray for bugs themselves.They never really got the place clean and the bug problem never disappeared. 

I would hire a professional to bomb or spray the building.
