So many of us or our family members have experienced this relatively mild though distressing infection. Pinworm is the most common worm infection in North America with up to 50% of some groups of school aged children getting infected. It is estimated that there are 500 million infections worldwide and 40 million at any one time in the U.S.
Pinworm, or Enterobius vermicularis, is a small intestinal roundworm about the size of a staple. The female adult worms leave the anus in the middle of the night while the person is sleeping to deposit her eggs around the skin of the perianal region.
The eggs become infectious within a couple of hours after being deposited and can survive for about 2 weeks outside the host.
Many people may be asymptomatic. In others there may be rectal itching and eczema, disturbed sleep, irritability, and secondary bacterial infection of scratched skin. Rarely worms are known to migrate into other areas like the vagina in young girls. Pinworms should be suspected in young girls with persistent vulvovaginitis.
The mode of infection with pinworm is through transfer of infective eggs by hand to mouth, frequently after scratching the perianal region and indirectly through clothing, bedding, food and other articles contaminated with eggs. Eggs get dispersed around the house, especially in the bedroom.
Pinworm infection is most common in school aged children, followed by preschoolers and is lowest in adults except for mothers of infected children. Whole families can get infected with this worm.
This infection is easily diagnosed by applying scotch-tape or a pinworm paddle to the perianal area and examining this microscopically for characteristic eggs. Specimen should be collected early morning before bathing or the passage of stools. Eggs are rarely found in stool samples.
In children over age two years, treatment usually includes either mebendazole (Vermox) or Pin-X (pyrantel pamoate), an over-the-counter alternative to Vermox that is available as a liquid.
One of the keys to treatment of pinworms is to repeat the dose in 2 weeks to be sure and kill newly hatched eggs. Also, since some family members may have a pinworm infestation without symptoms, it is sometimes recommended that the whole family be treated, taking caution in treating children under age 2 years and pregnant women (ask your doctor first).
Reinfection with pinworm occurs rather easily. Strict observance of good hand hygiene is essential (e.g. proper handwashing, maintaining clean short fingernails, avoiding nail biting, avoiding scratcing the perianal area) to prevent reinfection.
Other preventive measures include:
• Daily morning bathing and changing of underclothes helps remove a large proportion of pinworm eggs and can help prevent infection and reinfection. Showering may be preferred to avoid possible contamination of bath water.
• Careful handling (avoid shaking) and frequent laundering of underclothes, night clothes, towels, and bed sheets using hot water also helps reduce the chance of infection and reinfection by reducing environmental contamination with eggs.
• Clean and vacuum house daily for several days after treatment.

Why do they only come out at night and how do they know it’s night or bed time?
they are in connection with your mom so they kow when its bed time
It’s not just bed time about every 12 hours or when I am sleepy.
they are in connection with your mom so they know when it is a bed time
Oh boy. What I want to know is if they will crawl on over to my side of the bed and attack my precious anus?!
I just wanna know…like ik they dont cause any harm…but like can i use vasiline to stop the itching? if so that would be amazing
It’s not true that they only come out at night I experience it all day I can feel them coming out I can’t even sleep cuz of it
They come out all day. Infection is so bad the small microfilia come out of my ears and want go into my eyes. America is not a good place for this. Doctors don’t know what to do.
So true , i am at the point that , I’m. Really really sick. I just started eating garlic it’s helping But i went to emergency twice and they didn’t help me. I got the Reese’s and it’s in its way i am so swollen from this. Its really a horrible thing to go through.i i figured it out on my own. Good luck and try garlic cloves with honey just cut into slices put in a bowl with honey and drink water ..I’m eating 4 bug cloves a day and in 2 days i feel and see the difference.
Same I feel them during the day and they are out during the day for me but it’s worse at night where I haven’t slept a full night in a week and I haven’t got time to get medicine
I’ve been struggling with this shit for 12 months I cant get rid of these things I’ve tried almost everything….from doctor visits with negative results to upper and lower gi ….so lost dont know what to do I drink to stop feeling but it makes them worse
it’s daytime and i just saw one, they do come out at daytime :/
have you got rid of them?
What’s wrong with you guys, go to the chemist/drugstore and get some worming pills.
Ok like which one what’s the name of the medicine you use please help us my child of 3 years is suffering from this what can I do to help her
At night around 3pm two white colour worms came out from my 3 old daughter. She was crying all night and at 3pm i saw it for the first time in my life. Using earbud I removed it and applied coconut oil around her anus. Then she slept peacefully. It was a horrible night for us.
Warm baths and hydrocortisone cream help with the itch. I would make sure when I change you stand in the shower or tub. Gently remove your clothing keep disinfectant wipes by the toilet and wipe it after every use as well as cleaning tub or shower after every use. Shaving the area both front and back and in-between helps remove eggs
I believe pin-x or pyrantel paomate Is what you need Walgreens has it. I know it sounds nuts but listerine deluted w a lil water pat on the inside cheeks may slightly burn but not as bad as it already does and then a cooling numbness will allow your child to calm down and get some sleep.
Hahahah right?!?! Yuck
They are attracted to light, so at night if you go into a dark room and then shine a torch onto your anus you will see them come out if you have them. Also if you do have them then I suggest you go to the chemist and get medication for them right away.
OMG this is the worst I cant sleep and like it legit just feels like your being eaten by these worms and you just want it to stop but there is nothing you can do so you just SIT THERE
OMG! It is the same for me. My insurance won’t cover the meds.
I agree this is HELL. I’m a night owl & I cannot even think to do anything when I feel them. Always worse after going #2. I’m literally wanting to put the Reese’s pinworm med in a capsule and use as a suppository! I have already done so with black cumin oil, oregano & thyme essential oils & clove oil, coconut oil, flax seed oil, sadly it doesn’t make a diff for long, but it does help temporarily.
I have taken both 2 doses of reeses pinworm 2 weeks apart, as well as combatrin, which tastes like chocolate flavored exlax does & this is also made of the pyrantel pyramate. I read it kills them up to a year & works better than the banana chalk flavored stuff, but… Still having issues. Ready to Freakin snap! Probably resistant because I’ve done parasite cleanses recently with wormwood, black walnut & clove tincture…I mean how the hell are they still here. Has to be just resistant now or something! Lost.
im so done with this i have had this for a week now ugh im so mad i feel them every day
Hahahah right?!?! Yuck
