The reliable way to reduce bear visits is to deny bears access to every food and scent source—not only open meals. Store household garbage in a shed, garage, airtight container, or approved bear-resistant bin; put it out on collection morning; secure food, trash, toiletries, and cooking equipment at camp; and use only the backcountry storage method your destination allows.
Rules differ by park and community. A vehicle may be acceptable in one campground and prohibited in another, while some backcountry areas require a specific bear canister or locker. Check the current guidance for your exact destination before leaving home.
Why food and garbage management matters
Bears investigate more than an unattended sandwich. Drinks, trash, toiletries, cosmetics, sunscreen, insect repellant, fuel, coolers, grills, dishes, and other cooking or eating equipment can all provide a smell or reward that brings a bear closer to people.
The objective is not to prove that a particular bin or bag is impossible for a bear to smell. It is to prevent access and prevent a bear from learning that homes, campsites, trailheads, or vehicles are dependable food sources. The National Park Service summarizes the risk plainly: “Bears learn quickly and will return to areas where they find food.” Human food can change a bear’s behavior and increase risks for both wildlife and people. The related rule is equally direct: “Do not feed bears.”

Think of attractant management as a continuous routine: store everything before you need to leave it, clean as soon as you finish eating, and move waste into its final secure container rather than setting it beside a tent, picnic table, or door.
What counts as a bear attractant?
Use the broadest practical definition. If an item has a food smell, a flavoring, a cosmetic fragrance, or residue from cooking, treat it as an attractant until your park or local authority says otherwise.
| Attractant group | Examples identified in National Park Service guidance | What to do |
|---|---|---|
| Food and drinks | Meals, snacks, beverages, pet food, and ingredients | Keep secured whenever you are not actively preparing or eating them. |
| Food residue and waste | Trash, wrappers, scraps, leftovers, grease, and dirty dishes | Clean promptly and place every scrap and wrapper in the required secure container. |
| Personal-care products | Toiletries, cosmetics, sunscreen, and insect repellant | Store with food rather than leaving them in a tent, vehicle passenger area, or open camp box. |
| Cooking and camp equipment | Coolers, grills, fuel, pots, pans, plates, and utensils | Clean them and secure them whenever the site is unattended; local rules determine where they may be stored. |
| Household organic material | Ripe fruit and scraps from fish, meat, or fruit | Pick fruit as it ripens and do not put these scraps in compost where local guidance warns against it. |
The list is a management tool, not a guarantee that every item is regulated identically everywhere. A park may define “food” or “scented items” more broadly than another, so use the destination’s list when it is more restrictive.
At home: keep garbage inaccessible until collection
Residential garbage is often available for many hours before pickup. The safest routine is to keep it inside a shed or garage, or in an airtight container or approved bear-resistant trash container, and move it outdoors on the morning of collection rather than the night before. Local sanitation rules and container specifications differ, so confirm which containers your community accepts.
A practical household routine
- Contain waste immediately. Put food scraps, packaging, and other odorous material into the household garbage container instead of an open porch bag or uncovered can.
- Choose an indoor or approved location. A shed or garage is preferable when available. If your jurisdiction uses bear-resistant containers, use the approved category and follow its closure instructions.
- Reduce odor at the source. Double bagging can help mask odor, but it does not make garbage inaccessible. Keep the bags inside the secured container.
- Time curb placement. Put the container outside on collection morning, not the previous evening, unless local collection rules require another schedule.
- Manage yard food. Pick fruit as it ripens so fallen or overripe produce does not become a recurring food reward.
- Handle compost carefully. The National Park Service cautions against putting fish, meat, or fruit scraps in compost in bear country. Follow local compost rules and use a bear-resistant system if one is required.
Do not assume that a heavy-looking bin, a tied bag, or a closed lid is automatically bear-resistant. The relevant question is whether the container is an approved design and whether it is fully closed and maintained as directed.
At a developed campsite: secure the entire scent zone
At a campground, the risk area includes the picnic table, fire ring, tent, vehicle, and any locker or storage box. Secure food, garbage, and scented items promptly whenever you leave the site, go to sleep, or stop actively preparing a meal.

Before leaving the campsite unattended
- Put meals, snacks, drinks, pet food, toiletries, cosmetics, sunscreen, insect repellant, fuel, coolers, grills, dishes, and garbage into the storage method permitted at that campground.
- Wash dishes and cooking equipment. Remove food residue rather than leaving pots, plates, or utensils beside the fire ring.
- Collect every scrap, wrapper, and spill. Pack out food waste and garbage when the rules require it; never leave scraps for wildlife.
- Check the tent and backpack. Food and scented items should not be stored in either one.
- Close and secure the locker, vehicle, or other approved container before walking away.
National Park Service guidance warns that vehicle and locker rules are not uniform. Some parks allow food in a closed vehicle under specified conditions; others require food to be removed from vehicles and placed in lockers. Treat a car as acceptable only when the local rule explicitly allows it.
Rocky Mountain National Park example
Rocky Mountain National Park’s campground guidance illustrates how specific a local rule can be. It treats drinks, toiletries, cosmetics, pet food, coolers, grills, dishes, and garbage as items to secure. Visitors are directed to campground food lockers, or to specified vehicle storage when lockers are full, and coolers must be secured whenever the campsite is unattended. This is a Rocky Mountain rule and example, not a nationwide standard; another park may require a different method.

Do not choose a storage system solely because it worked on a previous trip. Before carrying food into the backcountry, check the destination’s current regulation. Depending on the area, you may be required to use a portable bear-resistant container, use a provided locker, or hang food. Some places allow more than one option; others approve only a particular container or model.
| Method | Where it may apply | Decision point |
|---|---|---|
| Portable bear canister | Backcountry areas that require or approve a canister | Confirm that your exact model appears on the destination’s approved list and that its capacity suits the group. |
| Park or campground locker | Developed campsites and some trail facilities | Use the locker exactly as directed; do not substitute a vehicle unless the local rule permits it. |
| Food hang | Locations where hanging is specifically allowed or required | Follow the destination’s hanging instructions, including any requirements for location and equipment. |
| Closed vehicle storage | Only parks that expressly allow it under stated conditions | Read the vehicle rule carefully; a closed car is not a universal substitute for a locker or canister. |
Capacity and group size matter, but the first filter is compliance. A large container that is not approved at your destination is the wrong choice, even if it would hold all your food.
Bear canister: what belongs inside
A canister is intended for the complete scent load, not only dinner. Put food, trash, toiletries, and other scented items inside. Keep the canister closed and locked even while you are sitting near camp; a bear should never be allowed to discover an open container and receive a reward.
Where to place a canister
Follow the park’s placement instructions. Keep the closed canister on stable ground away from cliffs and water, and do not attach ropes or straps that could let a bear carry it away. Distances are location-specific: Grand Teton guidance says at least 100 yards downwind from a tent, while Yosemite guidance says 25 to 50 feet from camp. These figures are examples of differing local rules, not a universal distance. Use the number and direction stated by your destination.

Approved models are destination-specific
Shenandoah National Park identifies bear-resistant containers as its preferred alternative and publishes an approved list that includes BearVault models. That listing does not mean every model is approved in every park. Check the current list for your route before buying, borrowing, or renting a canister.
Choosing, testing, and transporting your storage system
Make the storage decision before you shop or pack. First identify whether the need is household garbage, a developed campground, or a backcountry trip; each setting can have a different rule. Next read the destination’s approved-product list or storage instructions. Only then compare capacity for the number of people and nights, weight and portability, and whether everyone in the group can operate the closure correctly.
If you borrow or rent a container, verify the exact model and its condition rather than relying on the owner’s memory. Check that the lid closes and locks completely, that hinges and latches work, and that there are no cracks or missing parts. Practice opening and closing it at home, then plan where each attractant will go. A system that is technically approved but left partly open, overloaded, or misplaced does not meet the purpose of the rule.
At the trailhead, separate active-use items from stored items. Keep only the food being prepared outside the container; return the rest, along with toiletries and waste, as soon as the meal is over. If weather, a crowded campsite, or a changed itinerary prevents the planned storage method, stop and consult the local ranger or posted instructions rather than improvising with a tent, backpack, or unauthorized vehicle space.
Cleaning, packing out, and waste transfer
Storage is only effective if the camp is clean before the attractants are secured. Work through the site in the same order every time so small items are not forgotten.
- Finish the meal. Keep active food under control while people are eating; do not leave a cooler or open package unattended.
- Collect residue. Scrape plates and cookware, gather wrappers, and inspect the ground around the cooking area for dropped food.
- Wash equipment. Clean dishes, grills, pots, and utensils according to the site’s wastewater rules. Do not leave greasy equipment beside the tent.
- Package waste. Put scraps and garbage into the required secure container. Pack out all food scraps and garbage in the backcountry.
- Secure nonfood scents. Return toiletries, sunscreen, repellant, fuel, and cosmetics to the same locker, canister, hang, or other approved storage.
- Inspect before sleep or departure. Walk the site once more, including under tables and around the vehicle, then close and lock the storage system.
Never treat a wrapper, tea bag, beverage residue, or “empty” container as scent-free merely because no edible portion remains. The management rule is simpler: if it was used for food or carries a noticeable scent, secure it.

When a plan changes
Unexpected delays are when routines commonly fail. If a hike is extended, move all food and scented gear into the required storage before leaving the site, even if you expect to return soon. If a locker is full or damaged, do not leave items beside it; use the alternate method named by the campground or ask staff for direction. If a vehicle is permitted only under certain conditions, reread those conditions when weather or a late arrival changes where you park.
At home, a missed collection or holiday schedule means keeping the container secured for the extra period. Do not place a full bag on a porch, deck, or beside the garage while waiting. Likewise, fallen fruit after a storm and kitchen scraps during a busy week need the same prompt handling as normal waste. Consistency matters because an occasional reward can teach a bear to revisit the property.

| Mistake | Why it fails | Correction |
|---|---|---|
| Putting garbage out the night before pickup | It creates an accessible food source for hours. | Keep it indoors or in an approved bear-resistant container until collection morning. |
| Storing food or toiletries in a tent or backpack | Those spaces are not the required bear-storage system and can expose people at close range. | Move all food and scented items to the locker, canister, hang, or other method required locally. |
| Leaving a cooler beside the picnic table | A cooler is itself listed as an attractant and may be accessible when the site is unattended. | Secure the cooler wherever the campground rule directs; Rocky Mountain National Park, for example, requires it secured when unattended. |
| Assuming a vehicle is always safe | Vehicle policies vary by park. | Use a vehicle only when the destination expressly allows it under stated conditions. |
| Locking a canister only at night | An open canister near camp can still reward investigation during meal preparation. | Keep it closed and locked whenever it is not actively being opened for use. |
| Adding straps or a rope to a canister | A bear may be able to drag or carry the container. | Leave it unattached and place it on stable ground as the park directs. |
| Using a model without checking approval | Approved-container lists differ by destination. | Verify the exact model against the current park list before the trip. |
| Composting fish, meat, or fruit scraps | Those scraps can create an attractant near the home. | Follow local waste guidance and the National Park Service caution against putting these scraps in compost where it applies. |
A destination-check checklist
Use this checklist before departure and again when you arrive:
- What does the destination classify as food or a scented item?
- Is a locker, bear canister, food hang, or vehicle storage required?
- If a canister is required, is your exact model on the approved list?
- What are the local placement instructions, including distance, direction, and restrictions on straps?
- Where should garbage and wastewater go?
- When must food, coolers, and toiletries be secured—only when absent, or at all times outside active use?
- Does the community require garbage to remain indoors until collection morning?
- What is the current rule for fruit, compost, and household scraps?
Rules can be updated and some official pages carry older update dates. Verify the current regulation with the park or local authority immediately before travel rather than relying on a general rule remembered from another location.
The underlying principle
Every successful routine has the same result: a bear finds no accessible reward at your home, campsite, vehicle, or backcountry camp. Keeping food and garbage unavailable protects people from close encounters and reduces the chance that a bear will become conditioned to human food. The most effective system is therefore the one that matches the local rule and that you can keep fully closed, locked, cleaned, and correctly placed every time.

What counts as a bear attractant besides food?
National Park Service guidance includes drinks, trash, toiletries, cosmetics, sunscreen, insect repellant, fuel, coolers, grills, dishes, and other cooking or eating items. Treat anything with food residue or a noticeable scent as an attractant.
Should garbage go out the night before pickup?
Usually no. Keep it in a shed or garage, an airtight container, or an approved bear-resistant trash container, and put it outside on collection morning unless your local collection rule says otherwise. Double bagging may mask odor but does not replace secure storage.
Can I leave food in my car at a campground?
Only when that park expressly allows vehicle storage under stated conditions. Some parks require food removed from vehicles and placed in lockers, so a closed car is not a universal substitute.
Do I need a bear canister for backpacking?
It depends on the destination. Some areas require or approve portable canisters, some provide lockers, and some allow or require hanging. Check the current rule and approved-model list before the trip; a BearVault model approved by Shenandoah, for example, may not be approved everywhere.
What should go inside a bear canister?
Put food, trash, toiletries, and every other scented item inside. Keep it closed and locked even around camp, place it on stable ground away from cliffs and water as directed locally, and do not attach ropes or straps that could let a bear carry it away.
The Bottom Line
Secure every food and scent source, clean up immediately, keep household garbage inaccessible until collection morning, and follow the exact rules of your park or community. Local requirements—not convenience—determine whether you need a locker, bear canister, food hang, or permitted vehicle storage.
