    I've noticed that there aren't as many requests for BB IDs now that it's colder weather. Do they surface more in hot weather?

    BB development stops at 13C/55.5F so now that winter is kicking in a reduction in activity is to be expected in cold areas.

    For example from Usingers Monograph:

    Hatching to adult takes:

    58 days at 22C/72F,
    33C/91F it takes 37 days, but at
    18C/64F it takes 128 days.

    Metabolism will slow so the frequency of feeding will reduce with temperature as well. Of course a heated home will negate all that.

    There was a study done on this a couple of years ago in London. I managed to find a word doc. of the manuscript on the web here:

    http://trustk9.com/Are-bed-bug-infestations-on-the-increase-within-Greater-London.doc

    (Scroll down to the graphs if you don't fancy reading the whole thing.)

    They use calls to the local council pest control departments as a metric for number of bedbug infestations. Over several years they show clear cycles of increased activity in the summer months (for the reasons Spideyig mentioned), as well as a net increase year on year.

    But most BBs are indoors and most indoor places are kept around 75 F (just a guess)

    I would have thought BBs increase in the winter because ppl are bringing jackets around and hanging them at work/gym/etc.

    At my gym, theres a clothes rack and its packed TIGHT with jackets in the winter, Im thinking of going to the gym with no jacket!

    It's a good point, but you can't argue with the data

    I wonder if this is because bedbugs are nocturnal and most people allow their bedrooms to cool down at night? I would think night time temperatures would be a much better predictor of bedbug activity.

    I haven't seen data on this so, I'm just guessing.

    Biological effects are one thing. Behavioral effects are another.

    I did toss in the caveat about heated dwellings. Perhaps the cold reduces migration.

    Thanks for all the input.

    My apartment is super hot. For the first time, I want the thermostat lowered and my hubby wants it up. sigh.

    Still haven't seen evidence of bbs, but something is stinging me and biting me.
