Other than to drive you absolutely bananas, what is a bed bugs    environmental purpose? To begin with, its a common    misconception that there is a direct correlation between bed    bugs and a filthy environment. There isnt. Bed bugs are just    as happy to move in beneath Egyptian cotton sateen as they are    cotton dipped in motor oil.  
    Its commonly understood that bed bugs have no reason to    exist. There are no predators that consume them. They do not    pollinate and they offer no distinguishing benefit to their    surrounding environment. They simply do two thingseat and make    more bed bugs.  
    So, a bed bugs environmental purpose is nothing, at least    insofar as all of the knowledge we have of them and their    interactions with life and their surroundings. While that may    sound cruel, its not a question of eradication, simply one of    non-purpose. However, if you look for anything hard enough, you    often find something you didnt expect.

    When asked if he could have a magic wand, would he wave it and    make all bed    bugs disappear, Mickey Eubanks, a Texas A&M insect    ecologist said, Id wave it twice, just to be sure. As    far as spiders and other predatory arachnids or insects are    concerned, going after bedbugs is a waste of time.  
    Thats not to say that bedbugs dont end up as meals for    spiders but    it is to say that the spiders could do without. Life on this    planet is a series of cycles, most of which are easy enough to    decipher by simply observing our natural environment. The    problem with bed bugs is, there is no observable cycle in    relation to their environment.  
    However, like most other species on earth, a bed bugs    environmental purpose is a cycle of self-interested    survivability.  
    Bed bugs want what almost every living creature on earth wantsfood, shelter, and a source of water.    If you can provide those things, bed bugs    will move right on in and happily unpack their suitcases.    So, from the point of view of having a purpose, a bed bugs    purpose is to survive.  
    Its the things that bed bugs do to survive that drive us    crazy, such as infesting beds, the cracks, and crevices in bed    frames, couch cushions, and basically any upholstery that isnt    leather or some variation of it.  
    Looking at a bed bugs environmental purpose from the PoV of    the bed bug, it loves to reproduce. In fact, bed bugs reproduce    at an insane rate if they arent discovered and summarily    destroyed. If a female bed bug gets a bite to eat at her    favorite fast food restaurant (otherwise known as a part of    your body), she can begin the reproductive process.  
    The female bed bug is capable of producing between 1 and 7 eggs    per day for ten days, so long as she has access to blood a    single time. Thats between 10 and 70 eggs in a little over a    week. Since the female bed bug lives for up to a year, she can    lay a ton of eggs. Also, thats just one female.  
    Males also get pretty boisterous about mating after they have a    blood meal. Unfortunately, the type of mating bed bugs engage    in looks like the scene of a homicide. The male bed bug quite    literally gashes the female open to insert the sperm. The    female will then use this sperm to continually fertilize eggs    as she creates them.  
    This means the female can go without a male for a long time,    simply relying on the inseminated sperm to continually    fertilize new batches of eggs as she produces them.

    Theres not much to add to this other than the fact that bed    bugs are not a part of the all-important act of pollination. Without    pollination, its likely that the planet would not exist as it    does today. In fact, many scientists believe that life on Earth    would    come to an end, with the food chain broken.  
    Since bed bugs dont contribute to crop pollination, of which    75% of the entire planets supply requires pollination, theyre    irrelevant to the potential apocalypse.  
    Here is where most of the argument over the necessity of bed    bugs takes place. As for a bed bugs environmental purpose,    some believe that they are an important part of the food chain,    where spiders are concerned. Others believe that spiders    wouldnt suffer a bit if all the bed bugs in the world vanished    overnight.  
    It would be like taking corn dogs out of the freezer, with all    of your other frozen foods remaining. The corn dogs arent    exactly good for you anyway. The argument against a bed bugs    part in the food chain is a simple onethey only propagate in a    relatively obscure and secluded environment (aka your bed).  
    Bed bugs play no role in the control of other species because    they dont go after any other species. They only prefer to feast    on human beings (at least for the most part). Unless they    happen to transfer some wild disease, they may aggravate humans    but certainly dont kill them.

    The running theory is that bed bugs are descendants of bat    bugs, the latter of which decided (way back when human beings    were finger painting in caves) that human beings were far    more tasty than bats. At some point, these bed bug ancestors made    the decision to stick with humans exclusively and the rest is    history.  
    One thing that bed bugs havent done over the passage of    thousands and thousands of years is change much. Why bother?    Humans are yummy and readily available. Unfortunately, that    also means that bed bugs havent become an important and    inseparable part of the food chain either.  
    All they do is eat, breed, and come back for seconds.  
    One argument that can be made in favor of the existence of a    bed bugs environmental purpose is the spreading of disease.    That sounds weird, however, were applying purpose to bed    bugs and (outside of possible meals for spiders) there simply    isnt much to go on.  
    Once upon a time, it was assumed that bed bugs didnt really    pass on any diseases, at least not anything truly debilitating.    A study    conducted by the American Journal of Tropical Medicine and    Hygiene changed all of that.  
    The study found that Trypanosoma cruzi, a type of    parasite capable of spreading Chagas disease, can spread to    human beings via bed bug infestations and bites. Basically, the    bed bug delivers the vehicle and the vehicle delivers the    payload. Chagas disease is deadly, killing upwards of 50k    people each year.  
    Though it sounds ghastly, you might say that a bed bugs    environmental purpose is assistance in population control.  
    Theres very little in the way of scientific evidence that the    existence of bed bugs serves a necessary purpose. If they all    vanished overnight, we and the animals we share this planet    with would go on living just as we always have. In fact, many    of us would go on living in a more comfortable state,    especially at bedtime.  
    While that kind of determination wont blow anyones socks off,    its nice to know that bed bugs arent exactly a crucial    necessity. Sure, spiders eat them. But, thats the equivalent    of having a lone snack in the refrigerator that no one else    likes. Its all thats left so you might as well dig in.
