Residential and commercial bin cleaning in Guelph, Kitchener, Waterloo, Cambridge and Wellington County
Short answer: Garbage bins smell worse in August because heat speeds up the bacteria feeding on food residue, and that residue sits in places a rinse does not reach — the lid rim, hinges, handles, seams and bottom corners. To keep bins fresher: drain liquids before bagging, keep the lid fully closed, store bins in shade with airflow, and rinse fresh spills the same day. For residue that has already bonded to the plastic, hot-water pressure cleaning is what actually removes it.
August is the hardest month on a garbage bin. Warm temperatures accelerate what food residue, moisture, leaks and organic waste were already doing — and a bin can keep smelling long after collection day if residue is still on the walls, under the lid, or in the bottom corners.
Here is what actually works through the hottest part of summer, and what only masks the problem.
Why do garbage bins smell worse in August?
Because bin odour is a biological process, and heat is its accelerant. Bacteria feeding on food residue multiply far faster in warm conditions, and the by-products of that process are what you smell.
Three things have to be present: residue, moisture and time. Remove any one and the smell drops sharply. August works against you on all three — organic waste breaks down faster, condensation forms inside a closed bin, and a week between collections is long enough for a film to establish on the plastic.
How do you stop a garbage bin from smelling?
Control moisture first, then keep the lid sealed, then deal with residue before it dries on. This quick-reference table covers the most common causes:
| Problem | What to do | Why it works |
|---|---|---|
| Liquid pooling in the bottom | Drain liquids before bagging; double-bag and tie wet waste securely | Moisture plus warmth is what turns residue into odour |
| Drips reaching the base | Lay flat cardboard or flyer paper at the bottom; replace once damp | Catches drips before they bond to the plastic |
| Flies and animals getting in | Keep the lid fully closed; check nothing is caught on the rim | Flies need only a small gap to lay eggs |
| Smell lingering after collection | Rinse fresh spills the same day, then let the bin drain and dry fully | Dried residue bonds to plastic and needs heat and pressure to remove |
| Bin sitting in afternoon sun | Move to a shaded spot with airflow | Heat directly accelerates bacterial growth |
| Bin stored in a garage | Make sure it is fully dry before closing the space up | Shade helps, but poor airflow concentrates the odour |
One caution on absorbent liners: never leave damp cardboard sitting in the bin. Trapped moisture makes the problem worse, not better.
Which parts of a bin actually hold the smell?
The parts you cannot see. Lid rims, hinges, handles, seams and textured plastic trap residue that a rinse runs straight past — and because these areas stay damp, they are where recurring odour usually originates.
This is why a bin can look clean and still smell. The visible interior walls rinse easily; the rim and hinge assembly do not. Handles and lid edges are also the highest-contact surfaces on the bin, which matters beyond smell.
How do you get rid of maggots in a garbage bin?
Maggots are fly larvae, and in summer heat blowfly eggs can hatch within about a day — which is why a bin can go from fine to infested between collections.
To deal with them:
- Empty the bin completely on collection day
- Pour boiling water over the affected areas, or sprinkle salt directly on larvae to dehydrate them
- Scrub the rim, hinges and seams, not just the interior walls, since eggs are usually laid in crevices
- Let the bin dry fully before use — residual moisture invites re-infestation
- Bag all food waste tightly going forward, and keep the lid fully seated
Prevention beats treatment here. Flies are drawn by odour, so a bin that does not smell does not attract them in the first place.
Where should you store bins during summer?
In shade, with airflow. Direct afternoon sun turns a closed bin into an oven and speeds up everything you are trying to slow down.
A garage gives you the shade but often not the ventilation, which can make odour feel stronger indoors than out. If you store bins inside, let them dry completely before closing up the space.
Is rinsing a bin the same as cleaning it?
No. A rinse improves how a bin looks. It does not remove the film that causes the odour.
Residue that has dried and bonded to plastic — especially in corners, seams and around the lid — needs heat, pressure and a cleaning agent to lift. Deodorising on top of that film only layers fragrance over the source. It works properly once the residue is actually gone.
Should you clean your bins yourself or hire a service?
DIY handles fresh spills well. It struggles with bonded residue and creates a problem of its own: the runoff.
Hosing a bin out on your driveway sends contaminated water into the storm drain, which in most municipalities flows untreated into local waterways. Bin Clean’s mobile units use filtered, recycled water and capture the runoff on site, so nothing contaminated reaches the storm system. The system cleans with hot water and biodegradable products, then disinfects and deodorises high-contact areas like handles and lids.
Bin Clean recommends cleaning every two weeks to keep odour and bacteria under control through the warm months.
Make August your summer reset
Late summer is a sensible point to give bins real attention before cooler weather arrives. Clearing built-up residue now makes weekly waste routines easier and stops the smell carrying through the rest of the season.
The principle is simple: keep moisture down, prevent leaks, clean the areas that are easy to miss, and deal with residue before it has time to build.

Frequently asked questions
How often should you clean your garbage bins?
Bin Clean recommends every two weeks to keep odour and bacteria under control, particularly through summer. Monthly cleaning is usually sufficient in cooler months, and green or organic bins generally need more frequent attention than blue or grey bins.
Why does my garbage bin still smell after it has been emptied?
Because the smell comes from residue left on the bin, not the waste itself. A film of food residue on the walls, rim, hinges and bottom corners keeps producing odour after collection. Until that residue is removed, the bin will keep smelling.
How do you get rid of maggots in a garbage bin?
Empty the bin, pour boiling water over the affected areas or apply salt directly to the larvae, then scrub the rim, hinges and seams where eggs are typically laid. Let the bin dry fully before use. Keeping food waste tightly bagged and the lid closed prevents recurrence.
Does baking soda stop bin odour?
Baking soda absorbs some odour temporarily, but it does not remove the residue producing it. It is a reasonable stopgap between cleanings, not a substitute for removing the film from the plastic.
How much does professional bin cleaning cost?
Bin Clean’s residential pricing is $30 for the first bin and $15 for each additional bin on a one-time clean. Seasonal plans run $120 for four months of monthly cleaning or $240 for four months of weekly cleaning. More frequent service lowers the per-clean rate.
Do I need to be home for my bins to be cleaned?
No. Leave your bins at the curb after collection and the crew will clean them between 1:00 PM and 9:00 PM on your service day.
What areas does Bin Clean serve?
Bin Clean serves Guelph, Kitchener, Waterloo, Cambridge and Wellington County in Ontario, providing residential bin cleaning as well as commercial dumpster, trash compactor and trash chute cleaning.
