Why your trash can smells worse in summer

2 min read

If your can is bearable in winter but unbearable in July, you are not imagining it. Heat accelerates everything that makes a can smell, so summer calls for more frequent cleaning.

What heat does

Warmth speeds up the bacteria breaking down food waste, which produces more odor faster. In hot, humid conditions mold can start forming inside a neglected can in as little as 24 to 48 hours, and flies breed in days rather than weeks.

What to do about it

Move to a shorter cleaning cadence in the warm months, every two weeks instead of monthly if your can needs it. Keep the can in shade, bag your trash well, and rinse spills quickly. A sanitizing wash resets the can before the heat can turn it.

Common questions

Why does my trash can smell so bad in summer?+

Heat speeds up the bacteria that break down food waste, so odor builds faster, mold forms sooner, and flies breed quicker than in cooler months.

How often should I clean my cans in summer?+

Every two weeks is a good target in hot weather, versus monthly the rest of the year, especially for cans with a lot of food waste.
