Heat and humidity speed up decay
In hot weather the bacteria that break down food waste become active and produce sharp-smelling liquid within hours. On humid days nothing dries quickly, so the inside of the bin stays damp and holds the smell.
That is why the kitchen bin smells sooner in summer and needs attention more often than in winter.
What makes it worse
- Meat, fish and fat scraps in the bag
- Liquid pooling at the bottom of the bin
- A lid that does not close properly
- A bin beside the oven or in direct sun
- Thin bags that tear and leak
