A device 10 for removing an external parasite from a host comprises a substantially rectangular plate 11 having a projection 13 from a minor or major edge thereof The projection 13 is of a width less than half a length of the edge and comprises two prongs 134, 135 defining a first inward tapering V-shaped notch 131 between the prongs. The V-shaped notch 131 has a longitudinal axis aligned with an axis of the substantially rectangular plate 11. Opposed inner engagement faces of the prongs 134, 135 are chamfered for engaging substantially opposed sides respectively of the external parasite. One or more similar additional V-shaped notches 14, 15, smaller than the first V-shaped notch 131, may be provided on an edge opposed to the edge on which the projection 13 is located.
