How do I keep it from growing again
It's growing there because of damp & cold - moisture in the air in your home is cooled near external walls* or cold bridges, and will condense onto surfaces.
If there is insufficient ventilation, mould can and will form.
That doesn't really look like the black mould you often see on walls, probably due to the organic nature of the wooden surface giving rise to different moulds forming.
Treatment would be broadly the same though - Kill it with all the chemicals, then make sure it doesn't form again by improving ventilation (moving furniture away from walls, open window vents, extractor fans etc...), decreasing humidity / water vapour (caused by drying clothes, cooking, breathing, any external causes of damp ingress), and ultimately by improving wall insulation.
* London housing is often Victorian & older, with solid walls, and are piss-poor insulators.

Don't use bleach on Mold it will make it worse in the long run. Use a white Vinegar mix with water in a spray bottle. I sometimes add baking soda too.

Hi! Long time lurker here at LFGSS. Not sure if this is the right place to ask, I am new to the UK and first time living here in a cold country. Have 2 toddlers and wondering if the presence of black mold really affect their health?
Both of my kids are experiencing terrible vomitting last week. They immediately vomit after eating or drinking anything. Has taken them to the ER and doctors gave some liquid to them that suppress their symptoms. Doc said its winter fever?
Cue to today, after moving my bedframe, saw alot of black mold behind the bedframe and cleaned it up immediately with bleach+water solution. Is this the cause for their vomitting and should i be concerned about this? Have frantically flipped all other furniture to see if there is more mold hiding everywhere else...
How do I keep it from growing again and is bleach+water the best way to remove it?
TIA,
Zaraki
