there seems to be a lot of reports of bed bugs in buses and the tube in the UK as well as in France
I read Rob le Pest’s post about attracting them through sourdough. Other than making sourdough is there any product on sale generally in France, Brico, etc that might sell it?
Grateful for any replies
I wouldn’t have thought anyone would want to attract them, quite the opposite 
Often prefaced by them having arrived from Paris via Eurostar!
90% of this is urban myth, and comes round regularly. I had quite a young team in the office in London, often having never lived in London before, and they got quite hysterical about what they could catch from sitting on the Tube.
Which is not to say bed bugs don’t exist and are not a problem. But close examination of likely habitats is possible your first line of defence.
Way back in the late 80’s I bought a Vorwerk ET340 hoover (I’ve still got it and it’s still in use every day!). One of the reasons I bought it was it has fantastic sucking power and gets to dust that no other hoover can get to. The demonstrator asked me to test my own hoover on my mattress and then she tried the Vorwerk on it. I was gobsmacked when I saw how much dust it had collected. She said it was also good at sucking up bed bugs but use it for that job when you’re ready to change the bag. So for the past 30-odd years that’s what I’ve done and I don’t think I’ve ever had a bed bug in our bed and have definitely not been bitten by anything in bed!
Had the same, and the same demo. Time moves on and the Dyson cinetic cylinder has way more suction and way less fine particles back into the space. The Vorwerk was a very good machine for the 26 years I had it. In terms of mattress sanitising, I use my ozone generator from time to time. My wife saw a UV mattress vacuum on TV and I informed her the Ozone is 10 times more powerful and the Dyson 4 times the suction.
There’s probably a photo somewhere of @David_Spardo demoing one
