Ticks are blood feeders with an almost worldwide distribution. Most active stages require blood as a nutritive source and, in the case of adults, for sperm or egg production. Because of the mechanical processes and salivary secretions associated with blood feeding, the tick-host parasitic interaction is complex.
Tick-transmitted diseases are a major health issue for dogs as well as for cats. Even with preventative measures with products which are both repellent and acaricidal tick control is crucial.
