Bees at overflow pipe

[Dirk Diggler]

There's a couple of bees constantly hovering around my toilet overflow pipe. If I watch them for a while I can see some disappearing into the pipe. I'm a bit concerned that they're creating a nest/hive in there.

Has anyone dealt with something similar using a powder etc.? They're not there at night so I assume I could get an opportunity to put something there safely.

Help!

Will try a local bee keeper to see what they can offer. Cheers for replies.

@roge8014 thanks for the link. I don't think they are honey bees going by the photos. I'm unsure whether to just leave them for now but I have a 6 year old running around this garden and don't want her getting hurt by them.

There's actually 2 areas where they are forming now; the drain pipe and strangely a little ornamental statue that sits on the wall around 6ft from our patio furniture.
