Are they making a bee nest?

Observed: 1st June 2013 By: em13

We have lots of bee's coming and going from our insect house. I think they are honey bee's? They are bringing lots of vivid yellow pollen (rape seed pollen)? and then sealing off the ends. Are they making a nest or a larder?

Possibly Red Mason Bee's or a similar species which often nest in these custom made houses. They seal the end of the tubes with mud.

There seem to be lots of them

There seem to be lots of them coming and going, not just one solotary bee at a time. I will take photo of bee later if i can to aid identification.

I have two young children around is it best to relocate as its just behind the main patio?

Red mason bees - Osmia sp

Almost certainly Red Mason Bees - that's what these boxes are designed for. Reds, are similar to a honeybee to the layman but look closely, they have orangey-red furry bodies. They prefer a certain diameter hole , 6 or 7mm.
You may also see Blue Mason Bees (a metallic blue-black body) and later in year, Leafcutter bees (Megachile spp) that seal up the tubes with chewed leaf sections ( oftern from roses, those perfect little sections cut out that you see.

Mason Bees

In general, the various "non-Honey-Bee" types are very inoffensive. I believe many can sting, but seldom do so.
Unless you have someone with a known serious allergy, relocation is probably not required. Enjoy!
