Laboratory Identification of Arthropod Ectoparasites

For areas where tick paralysis is a concern, Stone has suggested that forcible removal using forceps may enhance the release of the paralysis-causing toxin in ticks capable of causing tick paralysis. An alternative method in this setting is to apply a pyrethrum-based insecticide directly to the tick to rapidly kill and facilitate spontaneous detachment. Further studies are needed to evaluate this method
