How to Deodorize a Crawlspace

A sour-smelling home can turn anyone's attitude grim. You sniff around the room trying to pinpoint exactly where the smell is coming from. You check the usual culprits, the trash can and garbage disposal, with no luck. That nasty smell might just be coming from your crawl space. A crawl space is the perfect spot for animals to do their business in and for mildew to grow. It can become a breeding ground for unpleasant smells. The good news is that there are a number of different techniques you can use to eliminate those smells.

Crawl spaces are the perfect breeding ground for horrible smells.

Step 1

Inspect the crawl space for dead animals. Mice and other animals will sometimes die inside your crawl space. As they decay, their corpses produce foul smells. If you locate a dead animal inside your crawl space, equip yourself with a pair of gloves and remove the body.

Step 2

Check your crawl space for mold or mildew. Mold and mildew can create a musty smell. If you find mold or mildew, clean the area with a mixture of 1 quart of bleach, 1 oz. of mild dishwashing liquid and 3 quarts of water.

Step 3

Sprinkle baking soda around the inside of the crawl space. Baking soda is a natural deodorizer that gets rid of odors without the use of harsh chemicals.

Step 4

Place bowls of white vinegar in your crawl space. Vinegar, like baking soda, is a natural deodorizer and can help eliminate odors.

Step 5

Scattering a few charcoal briquettes can also help alleviate odors in your crawl space.

Step 6

Toss a handful of mothballs in the area of the smell. Mothballs have a strong odor and can repel animals.

Step 7

Purchase yard and concrete deodorizer granules at your local home improvement store. Sprinkle the non-toxic, recyclable deodorizer granules inside your crawlspace.
