Bokashi and Wormery Troubleshooting: Questions Answered
If you’re just starting out, the practical questions pile up quickly. This page gives straight answers to the ones UK beginners ask most about bokashi and wormery troubleshooting, with links to the full guides where you need more detail.
Why is my Bokashi bin smelling like rotten eggs?
That sulphur stink means the lactic-acid bacteria have stalled and the waste has gone anaerobic, usually because the seal is broken or the bin is too cold. You need to check the lid gasket for cracks, ensure the bin is in a frost-free room, and add a fresh handful of bran to kickstart the fermentation again. Full details in our guide to Why Is My Bokashi Bin Not Working? UK Troubleshooting Guide.
Why does my wormery smell like a sewer?
A rotten-egg odour signals that the bedding is too wet or compacted, starving the worms of oxygen and creating an anaerobic environment. You should add dry carbon material like shredded cardboard or newspaper to absorb the excess moisture and gently stir the top layer to introduce air.

Is white mould in my Bokashi bin normal?
Seeing fluffy white growth on the surface is actually a sign that the beneficial microbes are thriving and the fermentation process is working correctly. As long as it smells sour like vinegar and looks like cotton wool, the waste is safe to bury and you do not need to panic. Full details in our guide to How to Fix White Mould in Your Bokashi Bin.
Should I cover food waste in my wormery?
Leaving scraps exposed on top of the bedding attracts fruit flies and creates an acidic environment that encourages pests to lay eggs. You should always bury fresh food waste under the top layer of moist bedding to keep it hidden and balanced. Full details in our guide to Are Fruit Flies in My Wormery Harmful?.
Will my composting worms survive a UK winter?
Most composting worms enter a state of dormancy when temperatures drop below 10°C, moving deep into the bedding and stopping eating, but they will not die unless the bin freezes solid. You can keep them safe by insulating the bin and ensuring the bedding stays dry and above freezing. Full details in our guide to Will Composting Worms Survive a UK Winter Outside?.
Why is there no liquid coming out of my Bokashi tap?
A lack of leachate usually means the bin is too dry or the tap mechanism is blocked by compacted waste, preventing the liquid from draining. You should check the tap for blockages and ensure you are adding enough bokashi bran to keep the moisture levels balanced. Full details in our guide to Why Is My Bokashi Bin Not Working?

What should I do if my wormery is too wet?
Grabbing a handful of bedding and finding it feels like a soaked sponge indicates the bin is anaerobic and at risk of rotting. You need to add dry carbon materials such as scrunched-up newspaper or cardboard to absorb the excess water and improve aeration. Full details in our guide to Why Does My Wormery Smell Bad UK? (And How to Fix It).
Why is my Bokashi bin leaking liquid?
Liquid escaping from the tap or lid usually means the seal is loose or the gasket is worn, allowing the acidic “tea” to leak into your kitchen. A quick snap-tighten of the lid or a replacement rubber gasket from a hardware shop will usually stop the mess. Full details in our guide to Why Is My Bokashi Bin Not Working?

Can I put meat and dairy in my wormery?
Adding meat, dairy, or large amounts of citrus can create a high-nitrogen environment that turns the bin sour and smells unpleasant. It is best to avoid these items or keep them to a minimum to maintain a healthy balance for the worms. Full details in our guide to Why Does My Wormery Smell Bad UK? (And How to Fix It).
How do I stop fruit flies from buzzing around my wormery?
Fruit flies are attracted to wet, acidic food waste left uncovered on the surface, so you need to cover new additions immediately with bedding. Ensuring the bin is not overly wet and burying scraps will eliminate the breeding ground for these pests. Full details in our guide to Are Fruit Flies in My Wormery Harmful?.
Why is my wormery full of green slime?
Green slime indicates anaerobic activity caused by excess moisture or lack of oxygen, which is different from the healthy white mould found in bokashi. You must stop adding wet waste and add dry carbon to dry out the bedding and restore airflow. Full details in our guide to Why Does My Wormery Smell Bad UK? (And How to Fix It).
Why are my worms not eating the food waste?
If the bedding is too dry, the worms will retreat and stop eating, while a bin that is too wet can suffocate them and stop digestion. You need to adjust the moisture levels to be damp but not soggy, similar to a wrung-out sponge. Full details in our guide to Why Does My Wormery Smell Bad UK? (And How to Fix It).
