    If there are no animals around or any suitable host or any "markers" (scents, heat etc) of suitable hosts, what do bed bugs do? I'm wondering if they wander around, or wait til a host comes or something else.

    To add onto this question: If there is no food, do the instars keep growing? I thought they require a blood meal to go from one instar to the next. I set up two Bird-X pheromone traps which claims it lures bedbugs from 2nd stage nymphs to adults. If I had only 1st instars and they aren't growing, does that mean my traps won't catch anything?

    No, they do require sustenance to grow and to molt to next stage.

    I'm not familiar with this trap. I don't know why it won't lure 1st stage nymphs to adults. All nymphal instars will be attracted to a host in order to feed, be it by carbon dioxide, heat or host odor.

    They carpool to the nearest Mcdonalds

    After 7-10 days of no food they start to get hungry so they wander to find food.

    If i left you in a house for a week or so with no food in the fridge what would you do? Id wander till i found something. Eventually they die if they don't get any food but they are pretty good at looking.

    I'm not an expert. I thought I read at one time that they get really good "signals" of potential food (movement, CO, etc). And, this is probably wrong, but if they are all in one room and hungry and one smart guy wanders to the guest room and finds you sleeping...don't they give off some "happy scent" to come over here...

    Again, Lou and other experts, I'm probably wrong and certainly not using the correct words.

    It might not even be that long of a time without food before they just wander.

    There have been mark and recapture studies and not all of them go over to the same place. If there is carbon dioxide while they wander, then that could draw them over.
    I've kept a male and female on paper in a small 1.5x1.5x0.5inch covered box. The male would always be in some other space in that box having crawled around during the night. The female may have crawled around but was back in the same place the next morning so it appeared not to move around a lot or actually didn't move around that much. She deposited eggs in that place. I've also kept small populations of 10-30 in those types of small boxes and individuals would clump together in the corners and folds of the paper but change positions over a short period of time. Even in a small box, they didn't all stay clumped together in only one place. No holes in the plastic to reduce any host odor seeping in.

    Hum , They do just like people do when there is no food in the house, wait around till they get really hungry then wander off some place else to find a meal or some one to feed them.
