Hi Cherry, when I had some sort of nasal parasites, mine were clear but with a red vein running down the length of them.
What I used besides the eucalyptus oil was dabbing hydrogen peroxide in the nasal area with a cotton swab. It seemed to really kill them immediately. I would then get another swab and clean out the nasal passages-- and that's when i'd drag out one or two of these thin clear worms. (They werent mucous either- but very firm with the mucous around them. If I rinsed them with water to see what they were, the mucous would wash away but they'd be there.)
Hydrogen peroxide really helped alot- with the cotton swabs. I will never be without cotton swabs since then and I still clean out my nasal passages with them as part of my hygene. Seems cleaning out the nose this way has also helped keep me from many sinus infections since then.
Many worms that end up in the nasal passages are merely larvea stages of adult worms in the digestive tract or lungs.
Cigarrette smoke -- including 2nd hand-- doesnt help matters with nasal parasites. neither does artificial chemical based air freshners or petroleum wax air freshner candles. I switched to essential oil freshners or natural scented candles
