Why Do Compost Bins Attract Raccoons?

Why do compost bins attract raccoons? Raccoons visit compost bins because the bin can hold food they eat. A University of Nebraska–Lincoln extension guide describes raccoons as omnivores whose diet ranges from eggs, carrion and food scraps to corn, crayfish, bird seed, worms, pet food and more. Meat, fish, eggs, fats, oil and dairy in a compost pile give a raccoon an easy meal, and the strong smell of those materials can make the pile easy to find. The fix is mostly about what goes in the bin and how the bin is closed.

Quick answer

Raccoons are omnivores, and food scraps are one of the things they eat.
University extension guidance says to use only plant and vegetable matter in compost piles, with no meat, eggs, fats or oils, to avoid attracting raccoons and other scavengers.
A University of Vermont extension article links foul odors and wet, slimy material to unwanted animal visits. It does not single out raccoons.
Keeping the pile covered and the bin closed on the top and sides are the main steps the sources describe.

What the person typing this wants to know

The person typing why do compost bins attract raccoons wants the cause before deciding what to change. They may have found a torn-up pile, a knocked-over lid or scattered scraps, and they want to know whether the bin is the reason. The short answer is that a bin becomes a draw when it gives raccoons food they can reach and a smell that leads them to it. The rest of this guide explains which parts of that are within your control and which the sources do not cover.

Food is the main draw

The Nebraska guide, NebGuide G1688 from the University of Nebraska–Lincoln, lists the foods raccoons eat, and its advice on compost is direct. Care should be taken to use only plant and vegetable matter, with no meat, eggs, fats or oils, in compost piles to avoid attracting raccoons, opossums, skunks and other scavengers. The same guide says to protect property by removing as many potential food sources as possible.

For a backyard bin, that means the material you add is the first thing to change. A bin that holds only plant matter gives a raccoon much less reason to visit than one that also takes kitchen leftovers from the meat, dairy or oily side of the kitchen. The guide does not rank how strongly each food draws raccoons, so this guide does not claim that one material is worse than another beyond what the sources state.

Smell and wet material

The University of Vermont Extension Master Gardener article on keeping wildlife away from compost says that many animals are attracted to compost for different reasons. It notes that foul odors come from poorly maintained compost, and it warns that excess moisture often results in a smelly, slimy mess that attracts flies and unwanted four-legged visitors. The article is written about wildlife in general, so it does not say which animals in particular a given smell will draw.

A pile that stays wet and smells strongly is therefore a warning sign. The UVM article treats smell and moisture as signs of a pile that is being poorly managed. Checking the pile for smell and wetness each time you open the bin is a practical way to see whether the pile needs attention.

What to keep out of the bin

The UVM article gives a clear list of materials to keep out of compost: dog or cat waste, meat or fish (raw or cooked), dairy products, oil and unrinsed eggshells. It says these will generate foul odors and potentially dangerous bacteria. Those materials overlap with the foods the Nebraska guide names, so leaving them out handles both the smell problem and the food problem.

What belongs in the bin is mostly plant material, such as fruit and vegetable scraps and yard waste. The UVM article says to cover each addition of food scraps with a layer of brown material, and it calls that step essential to prevent foul odors. A covering layer keeps fresh food out of sight at the surface, and it also helps the pile smell less. The article does not name a specific brown material for this step, so this guide does not name one.

Moisture, cover and turning

The UVM article ties excess moisture to the slimy, smelly mess that draws flies and larger animals. When you add wet kitchen scraps, pairing them with dry brown material is the balance the article describes. The article’s cover advice is the main step the sources give for controlling odor.

The sources we opened do not say how often to turn a pile to reduce animal visits, so this guide does not give a turning schedule. If you turn the pile, do it on a schedule you can keep. Watch the pile for smell and wetness as your guide, and adjust the cover layer when the pile smells or looks wet.

Bin design and lids

The UVM article advises selecting a hard-sided compost bin with a lid. A lid is the first barrier between an animal and the food inside. The same article describes placing a sheet of 1/4-inch hardware cloth, a fine metal mesh, under the bin. The article says this sheet is a barrier against small rodents that tunnel from underground. It is a rodent measure rather than a raccoon measure, but it shows the general idea: a bin that is closed on the top, sides and bottom gives animals fewer ways in.

The sources we opened do not compare lid designs, latches or bin brands, so this guide cannot say which lid works best against raccoons. Readers who want to compare bin styles can start with our guide to compost bins for small gardens.

Placement

Where a bin sits is a separate question from what goes in it. The sources we opened do not give a placement rule for raccoons, and this guide does not invent one. The UVM article does say to build the bin with a barrier underneath and a lid on top, which suggests the bin itself should be closed rather than left open in a corner of the yard. Keep food waste out of open garbage cans near the bin for the same reason: raccoons go where food is easy to reach.

How we chose

This guide was built from two readable sources opened on 2026-10-30. We chose them because each one covers compost and wildlife directly and because both come from university extension programs. The UVM article was reached through a same-domain redirect from its old address. We did not include a product list, because the question is about cause and neither source supports product picks. We also did not rank bin types, because neither source does that.

We quote only what the pages state. Where a point is general practice rather than something the sources say, we say so.

What we could not verify

How often raccoons visit a given compost bin. The sources give no visit rates or local population figures.
Whether a particular lid, latch or bin brand keeps raccoons out. The sources do not compare designs.
How far a bin should sit from a fence, shed or tree. The sources do not give a distance.
Whether a bin that follows the advice above will never attract an animal. The sources describe how to make a bin less attractive, not how to make it safe from every visit.
How often to turn a pile in order to reduce animal visits.

Frequently asked questions

Do raccoons eat compost itself?

The Nebraska guide describes raccoons as omnivores that eat food scraps, and it says to keep meat, eggs, fats and oils out of compost piles to avoid attracting them. The guide does not say raccoons eat finished compost, so this guide does not make that claim.

Is a bin with only leaves and grass clippings safe from raccoons?

The Nebraska guide points to plant and vegetable matter as the material to use. A bin of leaves and clippings fits that advice, but the sources do not promise that such a bin will never draw an animal. Keep the lid closed and the pile covered either way.

Should I stop composting kitchen scraps?

You do not have to. The UVM article lists dog or cat waste, meat, fish, dairy, oil and unrinsed eggshells as materials to keep out of compost. It does not say all kitchen scraps must go. Plant-based scraps are the material the sources point toward, and a cover layer helps control smell.

What if the bin is already torn up?

Start by checking the lid, the bin walls and the surface of the pile. Remove any exposed food and add a layer of brown material over the top. The sources we opened do not give repair steps for a damaged bin, so this guide does not give them.

Can I use an electric fence or a deterrent spray?

The sources we opened do not cover electric fences or repellent sprays for compost bins, so this guide cannot say whether they work. Check local rules before using any wildlife deterrent, and follow the product label if you choose one.

Does composting attract other animals too?

The UVM article says many animals are attracted to compost for different reasons and names flies and unwanted four-legged visitors among the problems that come with a wet, smelly pile. It does not list every animal, so this guide does not give a full list.

Bottom line

Raccoons come to compost bins for food and smell. Keep meat, fish, dairy, fats, oil and eggshells out of the pile, use plant and vegetable matter, cover fresh scraps with a layer of brown material, keep the pile from getting wet and smelly, and use a bin with a lid and closed sides. The sources do not promise that these steps stop every visit, but they remove the main reasons an animal has to come back.
