errrrm... just some "straight forward [1]" frank/candid rebuttal(?)follows;
"just spray with bt and move on"
Nope.
The product is designed for treating a living plant, capable of renewing itself.
Stored drawn frames do not rebuild themselves. Get enough WM in the zone and there
will be tears.
"honestly I quit reading it."
.. and right there is the true value of your comments now.
"And from what I read in the thread you have not used
it ... Just read about it.... correct ? ;-)"
Nope.
As just one of a few disciplines I bee master of these systems have been
designed/installed/maintained by yours truly over quite some years.
The methodology layed out is merely an adaptation of that work... freely given I add.
All the assumptions you make are addressed in that post of mine, links supplied (more reading).
"By the time you pay for the plastic, the tape, and
whatever it takes to get the gas and tanks... "
The setup laid out was for large quantities of stores over a likely commercial use - follow the
thread to get context. As many NH locations have the ultimate WM control sitting right under
their nose (metaphorical) the cost per year would be minimalistic compared to the status quo.
Switching the method to use in a hobbyist's apiary could be as simple as a small disposable
cylinder and a stopwatch.
Do the maths, I have... inert gas bombs over BT - and the host of other chemical alternatives
has to be a better cost deal and way more effective over wintering than the work required to
keep treating stacks in zones where the natural barrier for WM control is not in place.
Factor in the intended use of BT and the cost - it will have a shelf life - and whilst closer to
"organic" than anything else used, incuding electrically reliant alternatives, inert gas
(dry nitrogen) has to come out in front.
But new concepts carry a natural resistance in a closed loop bee management world.. as
recently noted by more than yours truly :-/
