Getting a bumble bee queen to nest in your garden.

... No harm in trying anyway. I'm quite optimistic about this one. I'd live in it, if I was a bumble bee.

Or you might get hornets, they go for empty nestboxes.

It'd be no issue to tape over the hole and relocate the stump, in that event.

C'mon then, how can I best seal this please?

I found a nice bit of clayey subsoil to do the trick. I'll just have to keep an eye on it to make sure it doesn't get washed out.

We are lucky and get a lot of different bees here. I think they like that our garden has a quite a few stretches of mountain stone old dry walls?

Silicone could seal the gap and screws hold it on may bee.
