rat urine smell in attic

0

We just bought a house and the attic was infested with roof rats. The pest control company has heavily baited and it has been two weeks & there seems to be no more rat activity. The problem is that he said it was the worst rat urine problem that he had ever seen! It must have been going on for several years. How do we neutralize this rat urine up in the attic that has soaked into the insulation? Or will I have to have all of my insulation removed and new insulation put in which will be a large expense that we were not counting on. Please advise us. Thanks.

There is no doubt roof rats can create a mess along with some nasty, foul and biologically unhealthy odors. Locally we have companies that specialize in insulation removal due to odor problems similar to what you've described. In my mind, removing the contaminated material is the only way to go. I suggest you remove as much as possible and then vacuum with an industrial shop vac to get anything loose. I also recommend using a RESPIRATOR, RUBBER GLOVES and DISPOSABLE COVERALLS to insure anyone working in this environment avoids the hazardous contaminates undoubtedly present.

I then suggest treating with the NNZ ODOR NEUTRALIZER. It does a great job of breaking down and eliminating odors and is very effective on both rodent droppings and their gland scent which undoubtedly is distributed throughout your attic space. I'd let the area sit for a few days before I reinsulated just to make sure the treatment was effective and to your satisfaction. In most cases we find people have to treat just once but in extreme situations a second spraying may be required. Based on the description you provided, that might be in order for you home.

On a side note, hiring a service company for this task will no doubt be quite expensive. I wouldn't be surprised if it would be a couple of thousand dollars depending on where you live, the size of the attic and some other factors. Doing it yourself would be a huge cost savings but obviously it will require some hard work.
