The honest answer: it depends on three things
- Heat. The single biggest factor. A bin degrades far faster in July than in January, so most households notice the problem seasonally rather than gradually.
- What goes in it. Households throwing out a lot of food waste, nappies or pet waste build residue much faster than households that mostly throw out packaging.
- How long it sits. A bin emptied weekly is in better shape than one that only goes out when it is full, because the contents spend less time decomposing in it.
A reasonable starting point
For most Northern Virginia households, cleaning the bins going into summer handles the worst of it — that is when heat turns a tolerable bin into a noticeable one. Households with heavy food waste, pets or small children in nappies tend to want it more often than that.
The more useful test is not a calendar at all: if you can smell the bin with the lid shut, or you hold your breath to put a bag in it, it is overdue regardless of when it was last done.
Signs it is past due
- You notice it from a few feet away, not just when the lid is open.
- There is visible residue baked onto the floor of the bin.
- Flies take an interest in it.
- The smell survives the bin being empty — a reliable sign the problem is the container, not the contents.
Does it need to be a subscription?
Plenty of bin cleaning companies would like it to be. It does not have to be. Cox Bin Cleaning has no subscription and no contract — book a clean when the bin needs one, at $25 for a single bin or $40 for the trash and recycling pair.
