Since situational awareness is half of staying alive, I thought this might be of interest to ETS members who travel farther afield.

There are reports of a particularly nasty insecticide (aluminum phosphide) being used to kill bedbugs in tourist hotels (particularly in Asia). If humans are carelessly/accidentally exposed, the effects are rapid and potentially fatal, and there is no antidote.

The source linked here is Wired!, so you can judge the credibility for yourself; but other news outlets have picked this up as well.

I'm not sure what average travellers could do to protect themselves, though.
