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, repellents and combs
Our standard test protocol closely mimics the conditions under which the test products are to be used. 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.
