Hi, This is going to seem like a strange question, but I've asked others with no success. Is it possible for small, tiny (very tiny)black flies to live on a human? If so, what are these flies and what can I do to get rid of them? | |

Dear Chelseamom, First of all, please allow me to assure you I dont question your sanity. Rather I quite sympathize with what seems to be a very perplexing and extremely annoying problem. Such distressing matters are made all the worse when one cannot find answers, especially from the supposed experts. However, you wouldnt be the first person to experience an unusual health or pest problem and be forced by circumstance to have to solve the mystery largely on your own. Again, please see the disclaimer at the bottom of the page stating that we as Researchers can provide general information only, which is not to be construed as medical diagnosis or professional advice of any kind. That said, lets see if we can find some information to hopefully augment what you already know about possible causes for your unfortunate and upsetting experience with these flies, and provide you some new paths to pursue: Since you see these insects fly, it would seem unlikely that you are experiencing an infestation of body lice or other similar pests since they do not fly. This would include such creatures as mites, ticks, bedbugs and fleas. Nevertheless, just in the interest of thoroughness, here are a few links describing these common and unpleasant pests, which you might like to have to use in the process of elimination, if nothing else: Here is an excellent page with photos of most human pests. The page is from Australia, but the photograph collection is excellent and extensive, covering not only Australian but general pests, and could be quite useful in identification or the process of elimination: http://medent.usyd.edu.au/photos/insect%20photos.htm Lecture: Insects Living on You: http://www.ent.orst.edu/burgettm/ent300_lecture15.htm Get This Bug Off of Me http://www.uky.edu/Agriculture/Entomology/ythfacts/stories/hurtrnot.htm Cutaneous [skin] Parasite Home Page: http://www.geocities.com/Athens/Delphi/9542/index.html Article on Parasitic Skin Infestations: http://www.drmhijazy.com/english/chapters/chapter12_2.htm#136 In addition to the foregoing, as the comment below from austin_trill-ga suggests, there is a very unpleasant infestation of the human body by a fly larvae, known as myiasis, which is a combination of two Latin words meaning fly and disease. In these cases the human (or animal) host is bitten by an insect carrying the larvae of another, which, through the bite, is then deposited in the skin of the human or animal, where it fastens itself and then proceeds to feed off the living tissue as it grows and matures. When the larvae matures it leaves the host and goes off to infect another insect and repeat the cycle. Basically it means you have maggots growing in your body. Lovely prospect, isnt it? This type of insect infestation is not especially rare, but is often missed or misdiagnosed in the U.S. and other civilized countries as it is far more common in rural areas of South and Central America as well as Africa. Unless a doctor in the U.S. is made aware that this is a possibility (s)he is likely to not consider it. Usually when it is found here, it is in someone who has just returned from traveling in an area where the condition is endemic. However, even if this is a possibility for you, the usual symptoms of localised swelling, intermittent pain, fever, malaise and somtimes pruritis or itching do not seem to pertain to your situation. Again, though, here are some links with detailed descriptions of various types of myiasis, and the particular species of flies that cause it, the most common of which is the human bot fly: Exotic Myiasis http://medent.usyd.edu.au/fact/myiasis.html Discussion of intestinal myiasis: http://www.cdc.gov/epo/mmwr/preview/mmwrhtml/00000503.htm One very unsettling example of human myiasis: http://www.vexman.com/botfly.htm Human Infestation With Rodent Botfly Larvae http://www.sma.org/smj/97feb22.htm Human myiasis caused by Phormia regina [black blowfly] in Pennsylvania http://www.japmaonline.org/cgi/content/abstract/80/11/600 Abstract from Medscape article on myiasis: http://www.medscape.com/viewarticle/410129_print Myiasis and control (more on livestock, but still has good info): http://www.roberth.u-net.com/myiasis.htm So, searching further while keeping your description in mind, I came across some information about gnats, or the tiny little fruit flies most of us are familiar with. On reading some of those descriptions, combined with the identification you received from the U. of Colorado, and also taking into account my own experiences with these annoying little pests over the years, it occurred to me to suggest the possibility that you are indeed being annoyed by these critters. Some things to consider would be what personal products you use and your individual habits and surroundings. Since these flies are drawn to organic matter, fruits in particular, is there any chance the shampoo you use, for instance, may, as many do, have some kind of organic or fruit base, i.e. do you favor strawberry, or peach or green apple products? How about conditioners, lotions, body washes, etc.? Is it your habit to carry food or fruit with you in a bag or purse? Do you keep fruit out on the counter or table in your home? Do you have houseplants, or any slow moving drains where a gelatinous organic layer may have built up? It may be that, since it is an observed fact that these flies do congregate around a persons head, you could simply be attracting them without realizing it due to your habits or surroundings, and theyre just acompanying you where you go. Another related possibility could be that, even if you are not carrying them with you, since they are quite ubiquitous, you may just be inadvertently attracting them wherever you go by something about your person that you just don't realize, such as perfume or the things mentioned above. That is only a suggestion, of course, but if you think it has merit, here are some links for you to investigate: Identifying flies (some links have pictures): http://www.adamspestcontrol.com/resources/smallflies.htm http://www.growinglifestyle.com.au/h/pest/fly/ http://ipcm.wisc.edu/programs/school/section_5/flies.htm Insects and Related Pests of Man and Animals with drawings and detailed descriptions: http://ipm.ncsu.edu/AG369/ The Ultimate Source for Fly Facts: http://www.pestcontrol-products.com/fly_facts.htm Good short description of gnats: http://home.howstuffworks.com/question688.htm The Bug Guy page: http://www.bug-guy.com/ Fruit flies and gnats in particular: http://www.bug-guy.com/FRUIT%20FLIES-GNATS.htm How to get rid of fruit flies: http://biology.dal.ca/facultyWeb/lloyd/fliesinyourkitchen.htm More advice on elimination: http://www.cindisullivan.com/temp/000046.php http://www.atlanticextermco.com/fruitflies.htm Comprehensive academic discussion of flies with further links: http://www2.ncsu.edu/unity/lockers/ftp/bwiegman/fly_html/diptera.html And just for, er, fun, or interesting further reading, some stories of human infestations by insects can be found at: http://www.snopes.com/horrors/insects/ I do hope the information provided is helpful, and the links will give you useful avenues to pursue in your quest to discover what the pests troubling you could possibly be.

There was recently a news story about flies living _in_ a person: http://in.news.yahoo.com/030624/43/25eim.html Not for the faint of heart! His condition is known as myiasis. |

Byrd - In looking at the sites your provided links to, I found a picture of the fruit fly. The site say the fruit fly always has red eyes. The fly I caught does not have red eyes. It's very tiny, black, has wings that appear traslucent almost, and it is two winged. Any thoughts as to what it might be? And thank you for all your kindness and help. Thanks |

I HAVE THE SAME THING!!! There are eggs/larvae?? which are reddish in color, very sticky and caustic, exist almost everywhere, and are present in my stool and mestrual flow. The buggers are also on my head under scabs (feels like Jell-O when touched) and they are also coming out of my skin, between my teeth, and in my eyes. There are TONS of the flies around the house, esp. in the bathroom. I feel that I injected the eggs intravenously via the water supply (flies come out of the overflow holes in the tub and sink) or they existed in the cocaine (the flies love my spoons). Cocaine is injected WITHOUT cooking. YOU ARE NOT NUTS!! THANKS FOR POSTING!! |

I have a couple of links for you... Also, I too have little black flies coming off me. I was at the bar yesterday and my friend seated next to me swatted at one. I also had one fly out from underneath the do-rag I wear at all times now this morning, and had one underneath my fingernail (must have picked it out of my hair). Always feel something moving on my scalp, which is scabbed over with yucky egglike things underneath. Check these links out please!! http://www,morgellons.org http://explorepub.com/articles/omar_10_2.html#top Thanks! |

I'm not an expert, but I believe this story, and have some thoughts that may be of help. Could it be that the cats either had, have, or are carriers of microsporum? Fungal infections are easily spread, and are tenacious. The dermatophytes sometimes give off a very fruity odour (among other things). I think this can attract the fruit flies, who may set up 'home' on the cat. Similarly, a fungal lesion can be caught by the owner, who may have, e.g. an open sore, and who may develop a dermatophyte infection, e.g. tinea capitas. I wonder if this can predispose to infestation with fruit flies. I think this is more than possible, and identify with tender areas felt in scalp area. I think it is great that you researchers gave such a comprehensive and open minded answer to this query, as such suffering must be taken seriously if it is to be helped. Best wishes, Lalla. |

I have the same thing. I've identified it as the phorid fly (looks almost like a cross between a mosquito and a fruit fly). This has been making me miserable - just recently I've started smearing vaseline on all areas of my skin, waiting 5 minutes, and repeatedly the wiping the area - and they are coming out in droves. The problem is I don't know what to do about the ones in my scalp, nose, ears, and believe it or not eyes. I get alot of pink eye - usually after a larva gets into my eye. I've had this for 10 years and only recently (last 2 weeks) have figured it out. I went to an emergency room about 3 years ago w/ a fruit fly myiasis theory and was almost committed for 'delusional parasitosis'. A couple of dermatologists later - I modified the theory using demodex mites as the culprit. I bought a microscope to prove it - but could never get any good mite specimens. About a month ago I noticed rows of bumps on my scrotum that felt like they had a razor stubble like hair in the center of each of them. Attempts to mess them them resulted in red rashes which really hurt. I put vaseline on them in an attempt to sooth the area - and lo and behold the bastards started coming out. I have identified a couple different larvae, pupae, and eggs using my microscope - I again thought they were fruit flys - but none of the literature made any sense. I knew they were small flies and I ran across references to the phorid fly and how it infests dead bodies in morgues and mausoleums. I know that this is the culprit. What do I need to do to get confirmation of this (without getting committed)? Anyone who is experiencing the same - please email me - we can help each other. |

I think this problem is often compounded by a fungal scalp infection, which is commonly caught from cats, or from fomites from their fur, deposited on soft furnishings etc. As I've said, dermatophytes often give off a fruity odour, (particularly when dying), and this is attractive to the keen sense of smell possessed by fruit flies. Furthermore, some dermatophytes, (invisible to the naked eye), growing rapidly and unchecked, branch into hyphae, then myceliae, both of which are visible, looking like whiteish threads. Minute pores are propagated and dropped, increasing the infection. The resourceful hyphae can change shape, e.g. appear 'fluffy', can 'sprout' hooks that burrow painfully into the scalp, and can inject allergens into the sufferer. Painful furuncles, or furunculosis, can occur in the scalp, sometimes resulting in secondary infection, and increasing the attractiveness to egg-laying flies, (or other biting insects with the eggs already laid on them). Larvae may opportunistically burrow into the ready made furuncles, and scalp myiasis has begun. When the larvae develop into flies, (and I'm not sure about the process of this. Is the next stage the pupae? If so, is this reached after the larvae have emerged from their furuncle, and do these mature into flies, possibly in a sticky substance in the hair?). Maybe those of you with a scientific background would know. I identify with those who have seen the mature flies fly off the hair, often in response to stimuli, such as scratching, combing, or the application of a substance such as vaseline, or alcohol based solution or spray. I believe that the maggots (larvae) obtain all of the nourishment, from the host tissue, including any necrotic area within the small furuncle, while the mature fly's role is simply to live a very short time, and to lay eggs. (This may only be true of some species, I am not an expert). I am unsure if the pupae 'feed' or not, or if they excrete any waste products. Although the mature flies may not be causing direct physical harm to the host, I advise killing them lest they lay eggs, or breed anywhere in the immediate environment. Any signs of infestation in the house must be destroyed, and all bins etc. scrubbed daily with dishwashing fluid, and rubbish secured and put outside immediately. Fruit flies dislike the cold, so I advise keeping food in the freezer, and keeping the fridge thoroughly clean and cold. Permethrin or Malathion will kill mature flies on contact, and sprays may treat soft furnishings, but excessive human absorption next to the skin, e.g., can be toxic. Do not spray near uncovered food, and any that has come into contact with flies should be discarded. Fly larvae live in the fatty subcutaneous tissue, (particularly in a furuncle, which they can 'burrow' into, or even make by themselves, by using hooks at their front), for some time, as they feed and grow. They have exterior spiny processes, so the movement of the creature is painful to the victim. I believe that some species can live there for weeks. Sometimes the 'respiratory movements' of the maggot are observable in the furuncle, or the saliva test can be done, entailing putting (your own) saliva on the furuncular surface. If this then froths, the presence of a maggot is indicated. The exudate of a clear serous fluid may also be visible, although the presence of pus indicates a possibly secondary, or alternative diagnosis entirely, of infection, (also requiring treatment, in either circumstance). Some dermatologists will expertly excise the maggot surgically, but great care must be taken so as not to break off parts of the creature, as fragments can set up a foreign body or host immune response, (due to allergenic substances released by the maggot when cut). This condition is more common in places like Africa, but is now apparently being seen in developed nations, such as North America and elsewhere. In Africa, it is understood that maggots depend on oxygen for survival, so anecdotal reports abound on ways to block off their breathing hole, visible on the furuncular surface. People have reported doing this by making a completely airtight seal for approximately 12 hours, e.g. with chewing gum or vaseline. The hypoxia makes the creature come near the top of the breathing hole making skilled removal easier, (care taken not to break the creature into parts, for the reasons already mentioned). Sometimes, people in Africa resort to placing fatty bacon (or similar) above the furuncle to tempt the creature out, and the more skilled among them can facilitate this process by very judicious squeezing when they spy the head of the maggot emerging, as it looks for food. I think this technique might be difficult to perfect, given the advisability of not causing the aforementioned breakage of the creature, so total smothering of it might be the better option. I think, if the maggots die, they do not have to be removed, (but will simply be reabsorbed), but antibiotics may be needed for any secondary infection, and the wound may need expert cleaning, and the removal of any other insect parts or debris, such as wings, legs etc. A recent North American report talks about a hitherto unknown phenomenon (in this jurisdiction), where well nourished patients had such debris, and other insect life, including a live caterpillar in one case, in scalp wounds. The presence of these foreign bodies caused an immunological reaction, and the patients' conditions improved dramatically in direct response to the debris being removed by the dermatologist concerned, who is now alerting colleagues to this novel development. Interestingly, the patients all had a positive history of preceding fungal infections, which he thinks may have attracted the insects due to the smells given off by these. Medical experts would be interested to see an excised maggot, (e.g. on chewing gum, or bacon fat), so preserve larvae in a sealed container filled with an alcoholic solution. I am not sure how to kill any eggs or pupae on the hair, but daily washing with alternating (e.g., medicated, then antifungal, then baby) shampoos and conditioners would certainly help, as would the laundering of segregated bed linen and towels extremely frequently (after each contact with the scalp), in very hot water and biological soap powder. Clean all segregated combs and brushes, after each use, and also daily, with bleach or strong detergents. Vacuum any brushed out debris from the floor immediately, and empty bag or container, as fruit flies can breed within the vacuum cleaner. Bathe or shower daily, and use different towels for the body and the scalp, and preferably consign these immediately to the boil wash, perhaps along with your pillow slips and nightwear. Consider buying cheapish items that you will discard after your programme of 'fighting back' is over. Do not not wash your hair in the bath, as any microorganisms that reside on your skin, such as streptococcus faecalis from the anal region, or staphylococci from the skin or nostrils may migrate to the scalp lesions, or the infestation or infection may spread from the scalp to other areas. You may be scratching your scalp during sleep, so keep fingernails scrupiously scrubbed and trim, certainly before you put them near your mouth, or food. The last thing you want is to inadvertently swallow larvae, as this may lead to vomiting and diarrhoea, at the very least. I am not suggesting anyone with this problem is dirty, but I think that a full on attack on it is required. I think that the pupae and larvae develop at different rates, so the overall process might have to be repeated, depending on the severity of the infestation. Tinea capitas, (which, if present, must be treated with systemic medication and the application of local antifungal treatment, and is infectious to others), can extend to the eyebrows and eyelashes, and both scalp and ophthalmic myiasis are recognised (albeit rare) conditions. I advise consulting a dermatologist and ophthalmologist. The home environment must be thoroughly cleaned and vacuumed daily to remove the fungus, and any pets effectively treated, (cats, e.g. can be carriers of fungal infection, even if they display no obvious signs of this). I would restrict their movements, (e.g. to one room with no soft furnishings or carpet, which I would clean daily with a bleach or detergent solution), and certainly would not allow them near the beds or any household linen. The interesting thing is that cats with any wound, or simply with matted fur, are very prone to 'fly strike' (myiasis), as are other animals, such as sheep. I do not know if susceptible humans (maybe with a genetic predisposition to this condition) can fall victim to this by virtue of being in the same environment. I, too, in common with the professional researchers running this helpful site, am not advising anyone to follow the steps I have outlined as though this were any kind of medical diagnosis or treatment. However, I have gleaned a lot of this from material that I have researched within the professional literature, so you may like to give it some thought, and consider engaging in your own reading of such sources. I just feel very sorry for you all who are suffering from this condition, especially if you have perhaps sought expert medical advice and have not initially felt that you have been believed. I sympathise particularly with Chelseamom, as she feels that her life has been ruined, and that she cannot form a relationship. I think, because her infestation has apparently reached a 'steady state', and has been going on for roughly ten years, that she possibly does not realise just how run down and ill she really feels. Once she achieves a total cure, (and she will if she is determined to do so, although this will take a lot of time and repeated effort), she will be amazed at just how well she feels. She may benefit from a vitamin supplement, as sometimes maggots can 'compete' for some vitamins, but she should check this out with a physician beforehand. I certainly believe her about the myiasis, and strongly suspect a concomitant tinea infection, partly because of animals scratching when she goes near them, because research suggests that hyphae 'communicate' over short distances. I hope that none of the above is offensive to anyone, as I am only trying, albeit in an amateurish way, to offer some points that may be of help to you. If you check the relevant sites, you will see that this almost obsessive regimen of cleanliness is required to eradicate both hyphae and fly infestation, and it is absolutely no reflection on your previous standards of hygiene that you have fallen prey to this. It is more likely due to your genetic predisposition, and perhaps to the increased use of efficient pesticides within farm animals that has led to humans now being the target of 'fly strike'!
