Einleitung

Regelmässig kommt es 4-6 Wochen nach den großen Schulferien zu Läusealarm in Kindergärten und Schulen. Läuseträger werden gemobbt, obwohl jeder bei Haar-zu-Haar-Kontakten von Läusen befallen werden kann. Es treten meist nur befruchtete Weibchen auf einen neuen Wirt über. Daher dauert es 4-5 Wochen, bis überhaupt Läuse bemerkt werden. Wenn nicht gleichzeitig alle Kinder/Personen behandelt werden, kommt es zu anhaltenden kostenträchtigen Ping-Pong-Infektionen. Pflanzliche Mittel wirken wenig und wirken potenziell allergen. Insektizide können auf bereits resistente Läusestämme treffen. Di- und Cyclomethicone wie auch ein liquides Bioprodukt wirken erstickend, wobei allerdings bei den Silikonen die Gefahr der leichten Entflammbarkeit besteht. Alle Produkte müssen aber stets bis auf die Kopfhaut aufgebracht werden, weil dort die meisten Läuse sitzen.

Abstract

Head lice in contrast to body lice do no transmit agents of disease. Nevertheless they cause panics in childyards and schools when they occur after long school holidays, since lice are (erroneously) kept for signs of dirtiness and antisocial behaviour. Therefore it is most important that parents frankly inform the mothers of all comrades and that a common treatment action is initiated. Otherwise repeated costful ping-pong infections will occur. Treatment can be done by plant extracts (with low efficacy and risk of allergies), with insecticides under increasing resistance risks, and by glueing di- and cyclomethicones respectively by fluid compounds which block the entrance of oxygen into the tracheal system of the lice. In case of di- and cyclomethicones it is important to treat in absence of fire, since together with hair heavy ignitions occur. In any case, however, any remedy must be applicated in a way totally covering the skin at the hair basis, where lice are sucking.
