4.4Special warnings for each target species
As the collar exerts its full effect after one week, the collar should preferably
be applied 1 week before animals are likely to become exposed to infestation.
Ticks and sandflies will be killed and fall off the host within 48 and 24 hours after
exposure respectively without having had a blood meal, as a rule. An attachment of
single ticks or bite of single sandflies after treatment cannot be excluded. For this
reason, a transmission of infectious diseases by ticks or sandflies cannot be
completely excluded if conditions are unfavourable.
For optimal control of flea infestations in multi-pet households, all dogs in the
household should be treated at the same time.
Fleas from pets often infest the animal’s basket, bedding and regular resting areas,
such as carpets and soft furnishings. These should be treated in cases of massive
infestation and upon the initiation of control measures with a suitable insecticide,
and vacuumed regularly.
