Weird bulbed grass/weed growing in garden

No, wild garlic has wider leaves than these look to be,

And wild garlic has a very distinct 'garlicky' smell

Few flowered leek/garlic is sometimes called wild garlic as well as ransoms and has narrower leaves - but also has a very definite smell!

I've had a check just to see, taking out a bunch running it under warm water to remove the frost and bring out any smell, there's not much of a smell admittedly the bulbs are maybe too small to bring out a smell. 

Here's an additional frost free indoor shot:



I'm not completely convinced this is Muscari, but I could be completely wrong....

Wild garlic has a very definite smell, even when frost bitten.

Sapindus

My guess would be Allium triquetrum or three-cornered leek.  It's invasive enough for it to be an offence to allow it to spread into the wild.

I was literally about the suggest the same - and the stuff is a menace! 

OP - have a feel of the leaves - do they grow out of the bulb in an almost triangular shape? (hence the "three cornered" bit). It will spread rampantly, but as you've already found out, the bulbs are also fairly easy to pull up. What we've always done is to loosen the soil around them with a hand fork then pull them out in clumps - paying attention to try to make sure that all the bulbs are removed - and that makes a big difference done regularly. We've been working on getting rid of the stuff in a very small garden area for nearly 20 years and it only takes one year of taking your eye off the ball on it and you can be back almost to square one very fast. The plus point is that the flowers re extremely pretty though! 

We also have Grape hyacinths which do spread, but far more slowly, and I certainly wouldn't describe them as any sort of pest.

If you only moved in within the year and have not seen it flowering, ask your neighbours?  If you have a moderately observant gardener either side, they may know what has been growing in the garden in the past.

I would also say it's likely to be Muscari, looks identical in winter to what was growing and flowering in my Essex garden. I never did know its name until now.

The leaves above the bulbs don't appear to have the triangular shape of Three-cornered Leek in the photo.

Just in case it needs saying...don't eat any bulbs until you are pretty sure you know what they are!
