(Pediculus capitis)
Biology:
The females of the head lice are up to 3.5 mm in size, the males somewhat smaller. The wingless insects have clasp-like legs with which they can hold on tightly and move along the hair. Their color is reddish to dark grey. They are well adapted to the temperature of the skin surface (optimum: 27 ° – 30 °C), live exclusively on blood and have to suck several times a day. The females attach their approx. 0.8 mm eggs (nits) very firmly to the hairline with a water-insoluble substance. The entire development cycle from egg to adult takes about 3 weeks.
damage:
Head lice infestations are very unpleasant. The saliva that enters the scalp during biting and sucking causes unpleasant itching. Local skin reactions such as redness or wheals often occur. Scratching often causes bacteria to enter the wounds, which can lead to extensive eczema. The transmission of lice usually occurs through direct contact from person to person or through the sharing of e.g. hats, caps, cloths, combs, brushes, towels, beds and items of clothing.
Tip:
In case of head lice infestation, countermeasures should be taken immediately with products available in pharmacies and drugstores.
