I like sourdough bread, pancakes etc but I hate the smell of the starter that pervades the house when it's out - any solutions?

[BewareTheBeardedDragon]

I started doing sourdough a couple of months ago and use the starter once or twice a week - usually to make pizza dough or pancakes, less often bread. I like the products of this, but as time has gone on the smell of the starter when it is sitting on the side bubbling has become more and more invasive
It is out at the moment, in prep for pancakes tomorrow morning, and when we got in from the school run I was shocked by the strong smell in the hallway. I don't want a house that smells like a sweaty locker room several times a week - what am I doing wrong? Is there a way to contain the smell while it's 'breathing'?

As your starter matures and strengthens I’m afraid that the smell also develops - it’s actually a really positive thing but can understand you might not be a fan of the smell...

I keep mine in a lidded jar in the fridge and then just take it out the night before I want to bake, feed it, cover it loosely then, once I’ve used it put it back in the fridge and don’t have any complaints ...what sort of flour did you make it with/ do you feed with?

I feed it with whatever I have to hand, which has been a mix of plain white flour and spelt flour so far. I suppose there is no way to contain the smell while it's out or it wouldn't be able to breath?

Mine lives in the fridge! I only ever do a big feed out of the fridge for the portion I am going to use to bake (about 24hrs in advance). I don't think I have ever smelt it other than from right up close.
