Apologies if this has been covered - I can find plenty of bed bug threads but none about this aspect. Like many people, I spend a lot of time in different hotel rooms in different locations and am increasingly worried about the risk of bringing unwanted visitors home with me. There is an article in the Sunday Times Travel section today about the bed bug epidemic hitting London and how the hotels should avail themselves of self-adhesive detection devices costing "£0.03 per room per day". This made me think that presumably there would be portable devices available that I could bring with me when travelling? A quick search reveals some product which seems to be simply a piece of cardboard in a box at £8, which doesn't work according to the Amazon reviews, and another one at £30, which is electricity-operated and thus no good for travelling to different continents. I presume some sort of cheap and cheerful disposable glue trap would do the job? Anybody know of any such device that is both affordable, portable and not dependent on availability of a particular voltage, and works?
