I purchased a Burgess fogger this summer to see how this technique worked. I

I have another piece of pest control equipment that would be better suited to
this task.  It is a "Microgen Microinjector".  It is a wall void fogger used
to treat cockroaches in cracks and crevices, carpenter ants in wall voids and
yes, occasionally feral honey bees.  It looks like a small stainless steel
suit case with hoses leading to a trigger controlled wand with a tiny tip on it.
It has an air compressor built into it, that mixes what ever material you put
into the revisor with air and breaks it down to a 5 micron droplet.  It was
made to be used with a vegetable oil base pesticide, however it will take just
about any thin liquid.  The Microinjector is adjustable, it can fog the inside
of a wall through an opening as small as a nail hole, or lay out a cloud
across a large room.  It needs a 110 outlet (or a good power inverter) to run and
it is a little heavy.

In the case of treating carpenter ants,  I would fill the revisor with a .5%
peritherin solution and "inject" the suspected wall through what ever nail
hole that was available.  After a short while I would see the smoky cloud "leak"
from cracks and crevices along the wall, eventually getting into the carpenter
ant nest.  The 5 micron droplet is small enough to enter the ants spiracles,
putting the insecticide directly into the ant.  A 5 micron droplet will also
cling to the hair of a honey bee.

My Microinjector cost $1,500 ten years ago.  I have seen them on Ebay for
$200.  I have no idea what they go for new today or if Microgen ever came out
with a lighter model.
