Subject: Re: GSBN:bugs in bales


<html>
<font size=3>Hi Bruce--&amp;nbsp;&amp;nbsp; It's probably no surprise to anyone,
but we have concluded that a bug problem is really a moisture
problem.&amp;nbsp; Solve the moisture issue, and the bugs -- beetles, mites,
whatever -- don't have suitable habitat. 
 
One more anecdotal story:&amp;nbsp; Some friends of friends in our region --
SW New Mexico at about 6,000' in altitude --reported getting thousands of
annoying (not biting) bugs coming from their strawbale walls.&amp;nbsp; They
had first appeared in spring (April), went away during the winter, then
came back the next spring.&amp;nbsp; When we went to check it out, we smelled
mold in one of the bedrooms on the north side, where the worst problem
was. 
 
While their stem-wall was minimal, we couldn't find any cracks in the
stucco, or other definitive explanations for moisture, until Pete asked
"Of course your roof is vented, right?"&amp;nbsp; Wrong.&amp;nbsp;
While these were partly owner/builders, they HAD worked with a contractor
who had done foundation &amp;amp; roof.&amp;nbsp; This "professional"
had not vented their metal roof. 
 
The homeowners had exacerbated the problem by keeping dozens (more than a
hundred) house plants, in the theory that they brought oxygen and would
help clean up their indoor air.&amp;nbsp; Of course the moisture they expired
made its way up to the roof, where it condensed and then ran down onto
the top of the bales and soaked in....&amp;nbsp; The north side seemed to be
the worst, which is consistent with the idea that sun on the south side
helped dry out the walls.&amp;nbsp; Also, there are more windows on the
south, hence fewer bales.&amp;nbsp; In the winter, the cold conditions did
not provide a nurturing environment, but with the advent of spring, the
tiny straw bugs were fruitful and multiplied. 
 
Fortunately we could see an fairly easy way for them to add soffits and
venting to their roof, and recommended that, which they did.&amp;nbsp;&amp;nbsp;
About a year later (this spring) they called back with questions about
potential moisture in the walls coming up from the ground.&amp;nbsp; Pete
went over with the moisture meter, and found the walls were within
accepted tolerances.&amp;nbsp; He reported that the family no longer had bugs
coming from the walls -- and while there was visible evidence of moisture
in the wall -- a small amount discolored wall inside and out on the north
side -- they appeared to have dried out.  
 
If you have any questions about this, let me know.&amp;nbsp; We could get
more specifics if need be.

Catherine

Subject: Bugs in sb in Northern Arizona...

Hi all,

Interesting timing for this inquiry that came today, since Bruce was just 
asking for instances and experiences with bugs. If anyone has any 
suggestions for Ed, I'll be glad to pass them along to him.

Thanks,

Warmest regards, 

David Eisenberg

David;

I have a question for you, and if you don't know the answer, could you 
forward the message to others?

I have a house that was finished one year ago.  Stucco was completed 
about Jan, 2003.  The client has had a problem with a bug infestation.  
They have tried different conventional pest control techniques but to 
no avail.  I seems that the bugs (Larger Pale Booklouse; Troglum 
puisotorium [or puisatorium]) accumulate (dead) near the base board 
where pesticide has been sprayed.
The walls are well sealed at joints and transistions to ceilings, 
walls, windows and doors, and have been painted with three coats of 
latex paint.  It is obvious to me that they are living in the straw 
bale walls.  The description of this insect states that it "lives and 
feeds on seed borne fungi and grain dust."   "Can be found in large 
numbers in aging bulk storage."  I have suggested to him to super heat 
the house to dry the walls out but right now we are in the middle of 
the monsoon season and the humidity is currently 46%.  We may be more 
likely to pull moisture in than drive it out.
Pyrethrum is another thought.  We could drill holes in the interior 
stucco and spray it in but I don't know if it should be in liquid or 
powder form.  I don't even know if it kills them.  Also I wonder what 
the hole spacing should be.
Any thoughts on buggy straw bale walls?  This is the first time I have 
heard of this.

I have been quite busy, I have finished two places, am almost finished 
with a greenhouse/barn and we are in the middle of doing some earth and 
lime plasters on another on.  We are getting ready to start Star School 
using the panelized straw bale system developed by Chris Magwood.


Thanks;

- --Ed

Hi all

This is the Australian Department of Primary Industries information sheet on
Psocids and Mites in Grain Storage.
Gives some interesting information on their living conditions, breeding
habits and the management of these wee critters.

Hi all -- 
 
After returning from an incredible and informative trip to the ISBBC and
around Europe, it seems to me that there may be a few straw-bale leaders
and innovators that are not on this GSBN listserve.&amp;nbsp;  
 
Bill -- can you check if Dirk Scharmer (Germany), Werner Schmidt
(Switzerland), Herwig van Soom (Belgium) or both Rolf Jacobson &amp;amp;
Arild Berg (Norway) are on the list?&amp;nbsp;  
 
If not, I would like to nominate them for membership.&amp;nbsp; Do I hear a
second? 
 
Of course I can come up with their email addresses as
necessary......
