Treatment of nursing bitches and queens controls flea infestations on both dam and offspring. Should re-treatment be necessary earlier than four weeks, do not treat more frequently than weekly. Re-infestation from the emergence of new fleas in the environment may continue to occur for six weeks or longer after treatment is initiated. More than one treatment may therefore be required, depending on the level of fleas in the environment. To aid the reduction of environmental challenges, the additional use of a suitable environmental treatment against adult fleas and developing stages is recommended. In order to reduce further the environmental challenge, it is recommended that all cats, dogs and rabbits in the household are treated. The product remains effective if the animal becomes wet, for example after exposure to heavy rain or after swimming (dogs). However, re-treatment may become necessary, depending on the presence of fleas in the environment. In these cases do not treat more frequently than once weekly. In the case of biting louse infestation in dogs, a veterinary examination 30 days after treatment is recommended as some animals may require a second treatment.
