Will blue tits return to same nest box and use net from last year?

Hoping someone can help us...

We have a pair of blue tits keep spending time in a nest box, which other / same? blue tits successfully nested in last year.

I've forgotten to take old nest out from last year, wondering whether its too late to remove / if birds which are spending a lot of time in then, will use it?

What to do? 

Many thanks

  • Hi Genkigal welcome to the community.
    It is probably a bit late to clean the box out now, the best time is around Sept/Oct in time for anything using it to roost in over winter.
    They may just build on top of the old nest, there is a pair of Blue Tits on my patch that uses the same hole in a tree every year that obviously never gets cleaned out unless they remove bits themselves.

  • Blue Tits nest in my neighbour air vent every year so they must just add to a little or take some of the old stuff out.
