Lice
We evaluate the efficacy of insecticides, repellents and also combs against head lice (Pediculus humanus capitis) according to the latest testmethods to be found in the scientific literature). Depending on the requirements, we conduct efficacy tests with formulations such as sprays, shampoos or treated textiles with adult lice and lice eggs at various ages.
Our test species is the body louse (Pediculus humanus humanus) which is closely related to the head louse (Pediculus humanus capitis). Both species are regarded morpho- or ecotypes of the same louse species and reveal almost identical appearance and biology.
Insecticides
Our standard test protocol closely mimics the conditions under which the test products are to be used.
Incubation of lice with test product on a hair strain 
Observation of lice mortality after treatment on a heating plate 
Treatment of lice with test product and incubation in a water bath 
Vital body lice egg
Repellents
We conduct efficacy tests with repellent products against adult lice according to the latest test methods to be found in the scientific literature, using real hairpieces, wigs, fabrics, hairbands etc. During the tests we observe whether the lice are repelled by the test product or whether, on the contrary, they enter the treated hair, remain and lay eggs there. Furthermore, it is evaluated if the test product dissolves the adhesive secretion with which the eggs are glued to the hair.
