As with fleas, the tick must not only be fought in the animal’s body, but also in the environment.
In all of its life stages (from larva to adult), the tick is very resistant. But the invisible forms of their life cycle, eggs and larvae, will remain in the environment and will survive for many months if appropriate measures are not taken.
In relation to public spaces. The most sensible solution to prevent the dog from catching ticks is to avoid taking it to infested places.
In the domestic environment, whether indoors or in the garden, all these places must be disinfected.
