If it is not entirely consumed, redose once with the full recommended dose as soon as possible. In geographic areas where flea infestations are seasonal, the treatment schedule should begin several weeks prior to the expected onset of infestations. If there is risk of exposure to fleas year-round, then treatment should continue the entire year without interruption. Ask your veterinarian for details concerning your geographic area and the most effective treatment schedule for your pet. All cats within the household should be treated with lufenuron suspension or tablets.
Fleas can reproduce on untreated dogs and cats and allow infestations to persist.
Lufenuron controls flea populations by preventing the development of flea eggs and does not kill adult fleas. Concurrent use of insecticides may be necessary for adequate control of adult fleas. Based on results of clinical studies, this emergence generally occurs during the first 30 to 60 days. In cooler climates, immature fleas may take longer to complete the life cycle and emerge as adults. However, these adult fleas will be unable to reproduce.
