Ticks

Adult females, once attached to an animal and fed, if they find a second tick in the same body to mate, lay about 10,000 eggs that hatch depending on the conditions from 3 weeks to months later. Dog ticks at appropriate temperatures live for about 2 months.
In Europe, tick-borne diseases are many and can be severe: Lyme disease, anaplasmosis, rickettsioses, babesiosis, viral crotonogenic encephalitis. The transmission of pathogens from infected ticks usually occurs from mid-spring to autumn and may end up in humans accidentally.
Pest control is done by spraying.
