If it's all block and just a retaining wall as I surmise, just mix up
some mortar and patch up the holes.



lol .. although they are very inactive at nite .. they are not
dead .. there is still 2 or 3 "security guards" buzzin about.

my wife is real happy though .. because .. that was her suggestion


and dont get me wrong .. I will probably try that .. running up
there and splatting some mud on it.

wait . . . how about that spray insulation stuff that expands ..
do ya think that would work ?

Depends on what type of bee it is...some would probably be able to work
through it altho not likely a honeybee could. I doubt it would last
long, but then again, after a few months you could knock it out and do
a real patch job.

But, I'd just spray the holes first, have the mortar ready and be in
long sleeves, etc., and go to it. A few buzzing around aren't likely
to be a major hassle unless they're Africanized or a hornet or similar.
