Infestations can be very difficult to handle in online science outreach projects. We do our best to give the best possible advice, but ultimately it’s an issue where you need boots on the ground.
During our infestation post, we mentioned that there were mental illnesses which made people believe they’re infested with parasites. Even with boots on the ground, this line can be hard to draw. People who have had real infestations, like the one below, often exhibit a hyper-vigilance which keeps them repeatedly checking for insects for years to come.
In other cases, people have obsessive thoughts that they are infested. They’ll often go to entomologists, and claim they’re infested. They’ll bring samples or specimens, which are free of anything which infests homes, pets, or people. Often times, they’ll travel from medical professional to medical professional in hopes that the medical professional will be able to take care of the issue.
The former case is willing (and often relieved) to discover their infestation has not returned. The latter case is unwilling to accept that they are not infested, and will often become angry or confrontational when given the “all clear” from a doctor or an entomologist.
That latter case, where people are unwilling to accept they do not have an infestation, is a legitimate mental illness called Ekbom syndrome by entomologists. It’s something which is very commonly encountered by insect scientists. Despite that, we do not receive training on how to handle this sort of psychological issue during our education.
So to better educate myself how to properly handle this, I wanted to write a post on here which revolves around how people in the medical profession recognize and ultimately handle this condition.
Trigger warning: This post discusses psychiatric disorders and will describe some forms of self-harm. We will not post anything gory below the fold, but we will discuss topics which may disturb some readers. Due to the sensitive and uncertain nature of this topic, we have opted not to post any of the queries which prompted this post.
What is Ekbom syndrome?
The medical literature refers to Ekbom syndrome by several names, including delusory parasitosis, delusional infestation, and Morgellon’s. This condition is usually treated as a subset of hypochondria or body dysmorphic disorder, and the two main symptoms are typically listed as follows:
Conviction of being infested by pathogens without any medical evidence for this, ranging from overvalued ideas to a fixed, unshakable belief.
Abnormal sensations in the skin which cannot be explained by a parasitic infestation.
It’s important to note that these people often have genuine sensations in the skin which resemble crawling or pricking from insects. In some cases sufferers will also see parasites, even when they’re not seen by an independent observer.
Based on my experiences, I’d like to add a few things to this definition which may help people recognize this condition:
- Freely offer samples or photographs for analysis, which are free of parasites. This is called the ‘specimen sign’ or ‘matchbox sign’.
- Many patients display signs of self-mutilation to various degrees. This can include sending pictures of sebaceous glands dissected from skin, to picking at areas of the body including the eyes, or describing attempts to self-treat the parasites in other highly invasive ways.
- When asked to give a description of the parasite lifecycle or behavior, will offer up a detailed description which does not match with the lifecycles of any known parasite species.
- When asked to describe previous treatments, the parasites will seem nearly immortal.
- Highly emotional or desperate pleas (you are my only hope, they’re in my bloodstream, I believe I am dying, etc).
- Will mention that they’ve cycled through an impressive list of doctors, medical specialists, and pest control companies, each of which was unable to solve the problem.
- It’s common for cases to involve significant others or pets.
- Often times, they will move from home to home in an attempt to escape the ‘infestation’.
- Many will isolate themselves to prevent the ‘spread’ of the parasites to others.
- Are unwilling to consider a psychosomatic cause, and are deeply offended at the mere suggestion of a psychosomatic illness.
This combination of symptoms makes these cases extremely difficult to handle. The name favored by medical professionals, delusory parasitosis, actually makes these patients reject medical help because they feel attacked by the term ‘delusional’. As a result I favor the term Ekbom syndrome, which has less judgemental implications.
Regardless of semantics their concern over parasites is ultimately psychiatric, and entomologists really aren’t in a position to help because we’re not qualified to diagnose this condition. In some cases, I’ve seen pest control professionals attempt to walk people who display many symptoms of the list above through self-treatment of the home with pesticides. Ekbom sufferers have a tendency to misuse pesticides, so treatment advice can further endanger their health.
Although Ekbom syndrome is described as rare by the medical literature, people who suffer from this condition will often seek out entomologists for help. It’s not uncommon to see this condition in insect identification groups, or when working in extension.
In addition to this, there are a lot of online ‘support’ groups which have sprung up around this illness. The term Morgellons, commonly used by these groups, is generally accepted to be a form of Ekbom’s syndrome. This sort of internet phenomena creates a type of cultural identify for people that suffer from Ekbom, and allows them to maintain their beliefs of infestation.
There are also a host of small pharmaceutical companies which market products to Ekbom sufferers, sometimes using loopholes that exempt supplements and homeopathic products from the sorts of testing the FDA uses to ensure that larger drug companies sell safe and effective products.
Although some of the medical literature says the condition is rare, it’s common enough to have an entire culture and economy which revolves around it.
What Can You Do?
As an entomologist, you should never attempt to diagnose someone, because you are not a doctor. I also believe that we shouldn’t be walking people through home treatments online, because that opens up a whole host of liability issues. However, we also must recognize that we’re in a position where we encounter legitimate medical conditions which include mental illness.
Interactions are key to convincing these people to seek help, and they have to be done a certain way. In order to handle these cases more effectively, I reached out to some dermatologists to ask for advice on how to handle these interactions in practice. I was fortunate enough to hear back from some of them, who were kind enough to send me their clinical guidelines on patient interactions. I felt some of these would be useful to other outreach specialists, and have paraphrased them below.
- Your goal is not to convince the patient they are delusional. This is a situation which should be handled delicately, and with sensitivity. They wish for their symptoms to be relieved, and they believe you can help them. Their belief they are infested with parasites is a fixed one, and debate will not lead to a productive outcome for either party.
- Be sympathetic, without discouraging or encouraging their beliefs. These people have seen many medical professionals before, and will be sensitive to frustration directed towards them. As much as possible, greet them with enthusiasm and a positive attitude. Always treat their suffering as genuine, because they are genuinely suffering.
- Allow the patient to express themselves freely, and set well-defined boundaries. Allowing the person to talk will build a rapport, relieve some of their stress, and will let them know you are taking their concerns seriously. When speaking with them, stand side-to-side with them instead of in front of them. Set a time limit on the interaction, and schedule appointments for times when you do not feel rushed. Ask straightforward yes/no questions. Accept that demeaning comments are a manifestation of their condition, and their frustration at not being able to relieve their symptoms. They may have trouble recognizing professional boundaries, which should also be regarded as a manifestation of their condition. Above all, make it known that you cannot definitively diagnose their condition because you are not a medical professional.
- Work with the patient to find a qualified medical professional. Be up-front and tell the patient that this is an issue which you are not equipped to solve and that more sensitive tests are needed. Work with them as much as you can to find a qualified medical professional such as a family doctor or a dermatologist. Since they regard this as a skin condition, a dermatologist seems to be the easiest sell to me…although I have no way of knowing whether they seek one out.
When helping these people out, it’s important to remember that the biggest challenge is getting them to accept medical help of any kind. Developing a trusting relationship is key to getting them help, although this is not easily balanced with the challenge of maintaining professionalism.
It’s also important to note that an entomologist cannot definitively diagnose Ekbom’s, or prescribe helpful medications. They must ultimately be treated by a dermatologist or other medical professional.
The Bottom Line
The key to helping people who suffer from Ekbom’s is to get them to a medical professional, and there is a very specific way dermatologists interact with these people which increases their chances of accepting the proper kind of help. As with SciComm, effective interactions are key to convincing them to accept help.
Describing the sorts of interactions dermatologists use to convince these people to seek the right specialist is a complicated affair, because they interact with these people in a medical context whereas we do not. However, I think that understanding these interactions may put us in a better position to help them a bit more effectively.
For my part, I only interact with this condition online…but many of my colleagues deal with this condition in person. My advice-which is to seek a dermatologist-has always been and will always be the same. However, I do feel like I need to give this advice a little bit differently from now on.

My brother is suffering with this. He is a single dad and last year was so obsessed he ripped up the flooring, baseboards, walls, kitchen of the home and had to move in with me and my husband for 6 months. He seemed to be improving and only had a few scary episodes of not sleeping because bugs were on/in him. He is back home and now escalating again. We need help, are there any support groups out there? V. Candee
Hello, I think I might have encountered someone with something like this, but they said they have been to many doctors that haven’t helped them, is there any specialist in Utah that I could send them to?
Morgellons has been found to be linked to Lyme disease and sufferers are infected by borelia burgdorfi which should serve as a reminder to entomologists and physicians to never label someone delusional without thorough examination and, above all else, LISTENING to patients. How did they think it made sense that thousands of people would have the same objective findings and subjective complaints and draw the conclusion that they were suffering from delusional psychosis? The CDC gets the prize for epic fail on Morgellons. The reason that they dropped the ball was because they were only examining the fibers left behind in the wounds, finding them non-organic and stamping CRAZY on the patients forehead. Meanwhile, their wounds were infected and they suffered tremendously.
