[kwlug-disc] (off-topic) bee nest inside brick wall

[CrankyOldBugger]

I hesitate to use chemicals on bees.  Bees are essential to the
environment, whereas wasps are just arseholes.  My house gets wasps, of
course.

Chemicals on wasps, sure, no problem.  I'll dump the whole inventory of Dow
Chemicals in between the bricks if I find wasps going in and out of there
(there is some sort of wasp killer available at Home Hardware).  When I
find a wasp nest, I unload a half a can of the foam stuff on it.

Wifeski did buy me some expanding foam to seal up the cracks between the
bricks.  Maybe this is the year when I'll get around to using it...

Back to the bees.  If they've started building their home in the walls then
they're in for the long haul.  You need to find some sort of incentive for
them to move elsewhere.  Maybe even buy those little bee hotels that they
can sleep in (basically a birdhouse with a bunch of tubes that the bees
crawl into), and install it away from the house.  You can get nice ones at
farm feed stores like the one in Heidelberg, if you go that way.

Not sure how well this will work if the bees are well established in your
house, but you could put a fake wasp nest nearby.  Wasps vs. Bees is the
fight of the century.  They won't go into each others' territory without a
good reason.  If you could convince the bees that your house is a wasp
house then they might move out.  That sometimes works, but not always.  You
can buy the fake nests at any dollar store, or CTC at least.

If you're serious about saving the bees, maybe contact a beekeeper in your
area?  I don't know but maybe they might come and do some sort of Pied
Piper thing to entice the bees away?  dunno..
