Depriving bed bugs of blood meals is not an efficient way for getting rid of bed bugs. In fact, an unfed adult bed bug can live up to one year without feeding on blood, as reported by several bed bug experts.

A well fed bed bug can live longer than one year, although it is currently hard to find documentation of what the average bed bug life expectancy is. Perhaps longer than one year, obviously – but considering that they are resilient and very adaptable pests, I would not be surprised if a single bed bug could live longer than several years or more with an abundant supply of blood meals.

  1.  L. Lloyd says:What this website overlooks and neglects to do, unfortunately, as do most of the other websites offering various “expertise” on the bed big problem, is to give a more definite definition of what “alive for a year without blood” actually, really means.Besides – it sounds really scary, right?“A bug that can live for a whole year without feeding, and yet finds some reason to feed on you every night, or every other night! The damned thing most know that it is ruining your sleep and sanity. It must be more intelligent than you are! You’re hopeless unless you try these products, first!”Think about it, folks – how would even the most educated scientist find out how long a bed bug lives without blood? Obviously, it would have to be only by a process of isolating individual bugs in containers, entirely by themselves, feeding them, and then seeing how long each of them takes to entirely die without feeding them. One cannot “tag” a bug and then let it out into the wild as one would a bear or a bird.So, some bug experts did this, at some point, perhaps over half a century ago when the bed bug problem was as it is now, and found out, eventually, that one or several of these bugs were able to “live” for well over a year, or at least many months. Then it was Written in Stone.What the current websites which cite this data do not ever seem to mention is that the question is NOT how long the average bug is showing signs of life, but how long it is able to STAY PREDATORY without eating.The famous Donner Party of American pioneers in the Sierra Nevada mountains of eastern California stayed alive for a long time – throughout the winter, in fact – but many of them were too weak to march out of the mountains or even find food for themselves, and so many of them perished after staying alive for a considerably long time – and they became weak rather quickly, too, since they also had to expend calories to simply keep themselves warm in the freezing conditions.The reason a bug or bugs are feeding on you as often as they are is because they probably cannot, in fact, stay viable and continue attacking you for all that long without a consistent meal – or else they wouldn’t be doing it, and they wouldn’t be so eager to hang around as close to you as possible once they know you’re a host – if they can go an entire year and be entirely robust, then why would they stay around a human’s bed so as to feed as often as possible?Why wouldn’t they just make a long journey every half year to where you are, and then leave and come back in half a year, etc? Feeding, for them, is clearly a dangerous proposition even when they hang around you, which is why they have evolved into the stealthy creatures that they are! They like to feed often for a reason- but stating simply that “they stay alive for many , many months without feeding” only serves to panic people and make them think that bed bugs are like Count Dracula. Bed bugs are not magical.So, yes, in fact – and in spite of what this website and several others are claiming – keeping the bugs from feeding on your blood for a consistent period of time WILL, in fact, weaken them to the point where they are much, much easier to deal with. Finding out where, exactly, that average point is (a week? two weeks? a month?) is something that no laboratory testimony on the internet which is generally quoted EVER seems to mention, and at this point I wonder if this has ever even been properly researched.These websites and media sources just tell you that it was found, once (and it was probably in some lab in the 194os 0r ’50s being sponsored by a pesticide company) that a bug was “able to stay alive” for a very long time without feeding – but that isn’t the pertinent info. See? Maybe it stayed alive, sure — but at what point was it too weak to crawl onto someone’s bed, or even climb vertically, for instance??So, YES — try to keep the bugs from feeding on you with mattress covers, frequent cleaning, and any other means that eventually make the things too weak to bother you. Don’t give up! Don’t allow illogical sites like this one make you give up or go around in circles with disinformation or half-truth info.
  2.  L. Lloyd says:And one more thing – I don’t mean “weaken them by ANY other means” because, of course, yu should not use “any” means… be logical andbe safe, and at least try, first , to block the bug’s access to where you sleep or are sedentary.DON’T crunch up the silica gel found in those little packages to keep shipped products dry and then throw it all over your floor, for instance – which is another dangerous thing to try (risky for your lungs) that people are expounding in their determination to do anything but be persistent about denying the bugs a host and to use simple scientific logic about how these insects behave.

Bed Bugs Lookout:

If you’re about to move to a new home or hall of residence, you might want to watch out for bed bugs before spending a night at the place. A newly built home might have new furnitures and beddings, thus, might have lesser probability of an infestation. But moving to a new home yet a not so new house, or a hall of residence should require you to have a lookout for these horrible pests.

Moving to a new home, you should always query about the history of bed bugs from the previous owners. You would want to be ready, having pest controllers checking out the place before moving in and settling down in your new place. Having a reliable pest controlling service for your home from time to time is also recommended to ensure no bed bugs or any other pests could take over your home and make it theirs.

If you’re a student moving into a hall, you’d know if bed bugs are a problem from the word of mouth. You should avoid any halls with such history if possible. Upon moving into a room, you should check your bed and beddings to ensure that no infestation is present. In case you do find or experience them, you should notify the hall’s management office and request for a new room as soon as possible. Bed bugs infestation is not always an easy quest to get rid of. In many cases, you will need a professional to do the job. Therefore, a new room would be best.

Don’t forget to keep a handy first aid-kit containing calamine lotion or any other antiseptic cream to help with treating bed bug bites if you’d ever have any. Infestation are not always easy to detect by sight so you might want to be ready with everything you’ve got.
