oxygen deprivation chamber on bbs?(8 posts)
After 6 months and 2 PCOs (7 chemical treatments) without seeing any bugs I got a K9 coming to my place and we finally could detect and see 1 bed bug.
I leave in an apartement. The wall of my room that gives to the exterior of the building is composed by a big window and a wood panel. There is no concrete wall: on the outside the building is made of epoxy panels. In between the wood and the epoxy panels there is a gap and that is where the bbs seem to be hiding... this means they probably have contact with other apartements and it explains why the treatments didn't work. So it will be very difficult to get rid of them without coordination from all the landlords.
I am waiting for their action but meanwhile I have already decided to move.
I know the risks of moving so I want to minimize them. Even if the k9 only detected bbs in the room wall wall, I am throwing out all my 2 rooms' furniture and some other furniture in a 2m radius from the rooms, as well as the couch (which the k9 cleared btw).
All my belongings have been treated (washing + drying, or freezer 2 weeks @ -25C) and I am thinking of having the k9 to come on the moving day to check all the furniture that I am taking with me (basically kitchen + some of my living room).
However I am still a bit paranoic so I have been investigating other possibilities and I found a local company that has a chamber for food and furniture treatment by oxygen depletion. They replace the oxygen by nitrogen in the chamber until it is less than 1%. They increase the temperature of the chamber to 35C and keep it like this for a week with the items inside. They say it is widely used on import export and worksd for bbs as well. I am thinking of putting my furniture there.
I would reckon this would indeed kill all living forms that need oxygen but did not find any documentation to prove it.
Also what about the eggs ? They probably don't need the same Oxygen ?
I personally would suggest that you get this confirmed before you take any further action including attempting to treat furniture.
So long without confirmation means there is a greatly reduced chance of this being bedbug related.
I know I have been over this ground with you before, if you have yet to confirm dont assume its bedbugs because that may be why the service you need is failing.
Bed Bugs Limited
Yes, I've heard of that plus one where argon is used rather than nitrogen. The argon treatments were at room temperature for 4 weeks. This procedure also used on museum artifacts for various insects including wood boring beetles.
Thanks for your reply. Yes, you are right, we have been over this and I contacted your friend in Zurich who said he could help but by that time I had already asked a detection dog to come over. When it came, the dog made a positive detection close to the wall. When the handler and my wife started inspecting the area, they saw what the handler identified as an adult bed bug crawling underneath the wood panel (my wife saw the bug running under the panel but cannot identify it)
For me however, this means visual identification was made. Would you say I would need more confirmation than that?
One thing is strange though: the fact that I kept getting bitten during all treatments... they still need to crawl 1m from the window to the bed and get exposed to the residual effect of the pesticide and I never found a dead bed bug anywhere.
Personally if I saw a bug run into such an area I would have the panel off to confirm because if it were bedbugs you would need to take it off to treat anyway and if it were not then I think the relief would soften the cost of the damage.
For me proof is a sample you can keep not something you think you may have seen and think was a bedbug. All these soft and illdefined maybes always remind me of dishonest product videos where things may or may not help. It's black or white, it is a bedbug and here it is or sorry I need to look harder or remove this to get to them.
Thanks for your reply David, I see your point. The big difficulty is that this wood panel supports the heater for the room which means taking it off needs the intervention from a plumber and cutting the heating system in the whole building which requires intervention from the building management. This WILL HAVE to be done, but I am having to convince the building management of that.
As you said before, the PCOs I hired don't really seem to be very professional but from the discussions I had with other PCOs in the area, these were the best of the lot. Having someone coming from Zurich would be quite expensive and seeing that I cannot take that panel off, it is not sure I would have any definitive conclusions.
As for trying to get a sample, the dog handler/technician really tried but was not fast enough in getting the tape. Meanwhille my wife saw the bug running to under the panel. The handler assured us it was an adult bb. That plus the fact the dog signaled the place is the best we got in 6 months (+bites and blood spots on the bed sheets).
But as you say I cannot be 100% sure and I surely would be more convinced with a sample.
However, in the meanwhile we are becoming very tired of all this... so we would like to try the moving option. As safely as we possibly can of course... we even discussed throwing everything away...
it is crazy but I have the feeling of being abandoned somehow as nobody cares or really tries to help: the PCOs come, do their standard thing and go saying it works almost 100% cases. Faced with the results they just keep saying it works most times. I feel I know more about bbs than they do. The building management tells me it is my business to deal with. I do all my best to avoid spreading, have been living with minimal (bagged) clothing on an almost empty appartement for 6 months, avoiding going to my friend's places and refusing people to come over. But at the end no one will really ever value that effort... I am just tired...
Sorry, sometimes just need to get it off my chest...
thanks for your help anyway and please... wish me luck,
I hear what you are saying but distill ing this down the barn that sticks in the back of my mind is as follows:
Why would a bedbug choose to ignore all the usual and common harbourages around the bed in order to locate itself in the panelling.
Given tht this is not typical behaviour for bedbugs and shall we say verging on the unique in a 10+ year experience I have to say the visual confirmation of a scutteling off bedbug does not wash with, neither does the too slow to catch it comment. Catch it or kill it but always show proof.
I appreciate your options are limited but if you costed your own time at even 1 Euro an hour I think you will agree your current strategy is actually not as cost effective as it may first appear. It may have even been cheaper to fly me over to have a look at the situation in person.
Thanks again for your insight. You are right, it is indeed puzzling. I had the same questions about the absence of bbs on the bed. I was assuming they were being repelled by the insecticide left by PCO treatments (7 total) but the thing is that I kept getting bitten... on the other hand bite numbers have decreased since the last treatment so there is some effect.
I should have an answer from the landlord during this week. Hopefully they will open that panel and we will find out. I will come back to this forum with the result.
