How to Reduce Garbage Can Odors—Especially in Hot Weather

Garbage can odors can be a real headache for homeowners, businesses, and property managers, especially when the summer heat cranks up those unpleasant smells. Here at Mountz Disposal, we recognize how important it is to keep your waste bins smelling fresh for your comfort, hygiene, and overall community well-being.

Why Do Garbage Cans Smell—And Why Is It Worse in the Heat?

The foul smell coming from garbage cans mainly comes from the decomposition of organic waste—such as food scraps, yard debris, and diapers—and the growth of odor-producing bacteria and mold. As temperatures rise, decomposition speeds up, bacteria reproduce more quickly, and those smelly compounds become more airborne, which makes the odors even stronger. That’s why summer tends to be the worst time for garbage can stench.

The Science Behind Odor Intensification in Hot Weather

• Faster Decomposition: Warm temperatures accelerate the breakdown of organic materials, leading to a quicker release of unpleasant gases.
• Increased Bacterial Activity: Bacteria flourish in warm, moist conditions, multiplying rapidly and generating even more odor-causing byproducts.
• Volatilization: Higher temperatures cause odor molecules to evaporate and spread more easily, making smells heavier and more pervasive.

Top Tips for Preventing and Eliminating Garbage Can Odors

1. Use Quality Bags Every Time

• Always opt for sturdy, high-quality garbage bags that are tear and leak-resistant.
• For particularly smelly or wet waste (like seafood, diapers, or meat scraps), double-bag it.
• Be sure to tie the bags tightly before tossing them in the can to minimize air exposure and prevent leaks.

2. Keep Organic Waste Out of the Can (When Possible)

• If your community allows, compost food scraps and yard waste.
• For very odorous waste (like meat or fish), consider freezing it until trash day to slow down the decomposition process.

3. Clean Cans Regularly—Don’t Wait for the Stink

• After each collection, give your bins a rinse with a hose.
• Use a long-handled brush along with dish soap and hot water to scrub off any stuck-on residue.
• Disinfect by mixing 1/4 cup of bleach with 2 gallons of water, or by using a commercial disinfectant spray. Make sure to rinse well and let them air dry.
• For a natural cleaning option, try vinegar or a mix of vinegar and baking soda to neutralize odors and kill off bacteria.

4. Let Them Dry—Moisture is Not Your Friend

• Moisture can be a breeding ground for bacteria and mold.
• After cleaning, keep the lid open to allow the can to dry out completely before adding new trash.
• To absorb moisture, sprinkle something like cat litter or baking soda at the bottom of the can.

5. Use Odor Absorbers: Baking Soda, Cat Litter, and More

• Baking Soda: Add a generous layer in the bottom of the can and inside new bags to absorb moisture and odors.
• Cat Litter: Pour a cup of unscented cat litter in the bottom to trap moisture and smells for several days.
• Activated Charcoal: A small bag or cup of activated charcoal can help neutralize persistent odors.
• Citrus Peels: Toss in some lemon, lime, or orange peels for a refreshing scent that helps combat odors.

6. Consider Deodorizing Products

• Scented or deodorizing trash bags can mask and reduce odors until collection day.
• Look for commercial odor-absorbing gels, pods, or sprays with ingredients like citronella or essential oils, which can be attached to the lid or placed inside the can for freshening.

7. Smart Location and Airflow

• Store outdoor bins in a shaded, well-ventilated spot to slow down decomposition and lessen odor intensity.
• If it’s safe, leave the lid slightly open after cleaning to promote airflow and drying, but make sure to close it properly after adding trash to keep pests out.
• Some people drill small holes near the top of the can for better ventilation, but be careful to avoid attracting pests or letting rainwater in.

8. Avoid Loose Trash

• Always bag your waste instead of putting loose items directly in the can. Make sure to tie the bags securely, too.
• For pet waste or diapers, use special odor-sealing bags before discarding.

9. Regular Schedule

• Frequently take out your trash, especially during the hot months.
• Don’t let food scraps or odor-prone materials linger in indoor bins—move them to outdoor bins as quickly as you can.
• If you can, only transfer trash to the outdoor bin the night before pickup to minimize how long it sits and decomposes in the heat.

10. Professional Cleaning Services

• Many communities now offer professional garbage can cleaning services that use high-pressure hot water and eco-friendly disinfectants to thoroughly clean and deodorize bins.
• Consider scheduling regular cleanings—monthly or quarterly—for the best hygiene and odor control.

Troubleshooting: What If the Smell Persists?

Even with diligent cleaning and odor control, some bins develop persistent odors due to years of residue buildup or porous plastic. Here’s what to try:

• Deep Clean: Fill the can with hot water and a strong cleaner (bleach, vinegar, or a commercial odor remover). Let it soak for several hours, then scrub and rinse thoroughly.
• Sunlight: After cleaning, place the can in direct sunlight with the lid open. UV rays help kill bacteria and neutralize odors naturally.
• Replace Old Bins: If a can remains smelly despite your best efforts, it may be time to request a replacement from your waste management provider.

Bonus Tips: Keeping Indoor Trash Cans Fresh

• Use smaller bins and empty them more often.
• Line the bottom of the bin with newspaper or paper towels to absorb leaks.
• Clean lids, handles, and foot pedals regularly with disinfectant wipes.
• Store bins away from heat sources (like ovens or radiators) to slow decomposition.

Eco-Friendly and Safe Practices

• Use biodegradable bags to minimize environmental impact.
• Avoid overusing harsh chemicals; opt for natural cleaners like vinegar and baking soda when possible.
• Never pour bleach or chemicals down storm drains—dispose of cleaning solutions responsibly.

Pest Prevention

• Keep lids closed tightly to deter raccoons, rodents, and insects.
• Rinse cans after spills or leaks to remove food residue that attracts pests.
• Consider using citronella-based odor absorbers, which can help repel insects as well as mask smells.
