What Causes Attic Odors And Strange Smells

If you've ever opened up your attic access hole, only to find one of the worst odors you have ever smelled in your whole life, I've been there too. What causes these horrible smells and what can you do about them?

Let's start with the cause of these smells, moisture, dirt, mold, mildew, dead animals, animals that make their home in your attic and the biggest problem of all is normally poor ventilation.

Poor ventilation is the biggest problem with musty smells in the attic. These smells are often caused from moisture accumulating in the building materials over time. If there is enough moisture in the attic, the wood will start to rot but this wouldn't be a normal situation, unless there was a roof or water leak.

Roof leaks can cause a constant supply of water to one part of the attic. This constant supply of water will eventually rot the wood and damage the ceiling. Water leaks from pipes can provide a steady supply of water and the situation can attracts termites and mold. Not a good thing.

One of the worst possible smells or odors in your attic would be a dead animal. Don't under estimate the size of some of these animals, they have found dead raccoons, cats, snakes, large birds, squirrels, rats and mice in some attics. These animals usually enter through damaged access holes or vent blocks, roof vents, large gaps, holes and even fireplace chimneys.

Once these animals die, their bodies start to decompose and produce one horrible odor. Once the body is completely decomposed, the smell usually goes away if the attic is ventilated properly. These smells can seep into the homes living area, often creating a room that no one wants to enter.

Animals that make their home in your attics, often create smells from urinating and defecating in the areas around their nest. Large birds like owls can become a problem over time.

Now that we've figured out some of the causes for attic odors and strange smells, what can we do to prevent this from happening and if it's already happened, how can we get rid of the smell.
