The Truth About Composting: Smells, Rodents, and Other Common Concerns
Many people are interested in composting but hesitate because they've heard stories about bad smells, rodents, insects, or complicated maintenance.
The good news? Most composting problems are preventable, and backyard composting is often much easier than people expect.
Let's tackle some of the most common concerns.
"Won't My Compost Smell Bad?"
A healthy compost pile should smell earthy, like a forest floor.
Strong odors usually indicate one of two problems:
Too many food scraps and not enough browns
Excess moisture and poor airflow
The solution is simple:
Add more dry leaves, shredded paper, or cardboard.
Turn the pile to introduce oxygen.
Avoid adding greasy foods, meat, or dairy.
"Will Compost Attract Rodents?"
Rodents are usually attracted by food sources that don't belong in backyard compost systems.
To prevent unwanted visitors:
Never add meat, fish, bones, or dairy.
Cover food scraps with browns every time you add them.
Use a rodent-resistant bin when possible.
Harvest finished compost regularly.
At Bountiful Cities, rodent-resistant compost bins built with hardware cloth have proven effective for community composting systems.
"What About Flies and Other Bugs?"
Some insects are actually part of the composting process.
However, excessive fruit flies often mean food scraps are exposed.
To reduce pests:
Bury food scraps beneath browns.
Keep a lid on kitchen scrap containers.
Freeze scraps until you're ready to add them.
Common Composting Mistakes
Too Many Greens
Food scraps alone create a wet, compacted pile.
Balance greens with carbon-rich browns.
Too Dry
If decomposition slows down, the pile may need water.
Aim for the moisture level of a wrung-out sponge.
Too Small
Tiny piles dry out quickly and decompose slowly.
Larger piles generally compost more efficiently.
Expecting Instant Results
Composting takes time. Depending on conditions, finished compost may take six to twelve months to develop.
Composting Doesn't Have to Be Perfect
One of the biggest misconceptions about composting is that it requires constant attention.
In reality, composting is a forgiving process. Even if conditions aren't perfect, organic materials will still break down over time.
Start simple. Learn as you go. Most people discover that composting becomes a routine habit within a few weeks.

As discussed in our first blog on this series, according to the EPA, food waste makes up roughly 24% of municipal solid waste sent to landfills, making it the single largest category of landfilled material in the United States. By composting food scraps at home or at community composting sites, we can keep valuable nutrients in circulation, build healthier soils, reduce methane emissions, and move our communities toward a more resilient local food system.
