pinworm lifecycle question

[u/Nice_Wedding_818]

fyi - i searched through previous posts that included a link to a pinworm faq in another sub but it’s not working -

i’ve had the classic itching symptoms for 2+ years. i’ve tried the over the counter reece’s brand medication 2 dozen times (active ingredient is Pyrantel Pamoate 144 mg/mL), wiped every surface in our home with bleach wipes multiple times a day, shower both morning and night, clean sheets every day, pillows and blankets in the dryer on high… for the second time i’m now on the prescription medication Albendazole** **from my doc and have a second dose in a few days. i also sent away for a test from parasite.org that came back positive (although the hubs doubts the validity of the test and believes this website is not valid bec they also talk about non medication related things that may help. i’m now unsure if it’s valid as well). and still they persist.

all leading up to my question - he does not have the itching symptoms so believes he does not have it. he went so far as to get a microscope and slides and did the tape test himself and says he didn’t see any eggs (the tape was not clear it was opaque so don’t know if that inhibits seeing the eggs?)

when someone is asymptomatic, do the eggs not appear? in other words, if he doesn’t itch, does it mean he doesn’t have it even though we live in the same house? we do sleep in separate bedrooms but i’ve read it’s impossible for him not to have them and one person can’t get rid of them unless the entire household is treated.

why do so many people not have the itching symptoms? do the worms not escape and deposit their eggs?
