In MN were required by city before rental license is issued to attend Drug Class to identify, and know when to issue a non-compliance with the Crime Free / Drug Free Addendum.This helps enforce and we are able to file for cause with this,, I don't need a police report or anything else. as long as I took the class was certified by Police Dept I know what the odor is and how to handle it if it's a problem along with other drug use that was covered.. 

My @$$, how about immediately after the animal fouled the yard!

So as the post says, this rental stinks after tenants moved. Has anyone dealt with this, and remedies please, I did allow 2 pets. 

They make some great products to essentially seal off bad odors like smoke and pet and we have been in some incredibly bad pet odor damaged homes! 

As you begin the drying process, you may inadvertently cause the mold to "bloom" and become active as you lower the water activity levels.The musty mold odor you are familiar with and do not smell in this basement is known as "MVOC" or microbial volatile organic compounds.

There wasn't residue, lasting odor, etc. so I don't believe it was ongoing.  

AndreaAndrea Short,Can you smell the odor of Tampa Electricity in your area?

I use Concrobium from Lowes because it seems to work and doesn't have an off-putting odor.

Pictures are shown below but the one thing that is missing from the photos is the putrid smell of cat urine and feces (along with other odors too).  

No harm no foul.
