Help - live threadworms seen over 3 days after treatment

[MiddleTibble]

Does that mean the treatment hasn't worked or does it take this long to kill the buggers? Have been hoovering, dusting , and cleaning like a mad thing and want them gone.

I can't seem to find online how long it actually takes for the ovex stuff to kill them but found live one last night 80 hours after medication. Does this mean it hasn't worked or can it take this long to banish them from the first round of medication? I know we'll all take a second dose two weeks after the first, but the thought of this itching for two weeks is not worth thinking about.

old fashioned solution-think 70+ years ago- my mum used to extract them manually when they came out at night usually.
