Entomologist Michael Merchant of the Texas AgriLife Extension has recently compiled a really interesting two-part series of blog posts on his Insects in the City blog, covering some of the interesting bed bug-related presentations at the 2011 Entomological Society of America conference in Reno.

The Bed Bug Chronicles Part I describes the following:

  • Changlu Wang’s research on the use of dry ice to kill bed bugs in large garbage bags.  (It worked, but my hunch is it may not be safe/practical for all users.)
  • Dini Miller’s research on the use of Nuvan ProStrips to kill bed bugs in 42 gal. garbage bags. Warning: use according to the label was not terribly effective and even off-label use at higher than label rates was not enough to kill all life stages.  This was especially disturbing to me, considering how many PMPs seem to be setting up clients with DDVP strips in garbage bags.
  • Susan Jones’s research showing that over-the-counter bug bombs (total release aerosols) are not effective in killing bed bugs.  Yes, we know this, and have heard this repeatedly from experts, but perhaps the documentation provided by this research will help encourage the industry to stop marketing these products?
  • Additional research on freezing, pyrethroid resistant bed bugs, and Wolbachia, the bacterial parasite that lives on bed bugs.

The Bed Bug Chronicles Part II highlights two developments in bed bug monitoring:

  • Work by Narinderpal Singh and Changlu Wang at Rutgers on how to make pitfall traps (specifically the ClimbUp  Insect Interceptor (R) trap more attractive to bed bugs, using various lures.  The big winner was nonanal (aka nonanaldehyde or pelargonaldehyde), which is given off by humans.
  • FMC’s Verifi (TM) trap, which is set to be launched in January and of which not much is known.  Merchant notes the product has a “secret attractant” which isn’t currently being disclosed.
These articles, particularly the first, are immensely valuable for those of us who can’t attend these meetings.  I know you will want to go to The Bed Bug Chronicles Part I and  The Bed Bug Chronicles Part II, in order to get Dr. Merchant’s full impressions.
Many thanks to Mike Merchant for sharing his notes and analysis with his readers.

Thank you. I’m particularly glad to know about the parasite that lives on bed bugs.
