Reg. NO. 32573 P.C.P. ACT




EctoShield™ Topical Solution Medium and Large Cat will control fleas on cats within 1 day of treatment and will continue to protect the cat from further flea infestation for up to 4 weeks. Reinfestation from the emergence of new fleas in the environment may continue to occur for 6 weeks or longer after treatment is initiated. Reapply every 4 weeks for continual pest control in situations where there is an ongoing risk of pest infestation. Treatment must only be repeated if pest problem reoccurs. If re-treatment becomes necessary earlier than 4 weeks, do not re-treat more than once weekly. Shampooing of the cat may shorten the duration of flea protection, therefore, re-application following shampooing is recommended. For effective flea control, treatment of the pet should be combined with the sanitation of any area used by the pet. Vacuum floors, carpets and furniture (discard vacuum bag after use) and wash the pet’s bedding, living quarters and surrounding areas. If pest problems persist, an insecticidal premise treatment may be required. For use on pregnant/lactating animals consult your veterinarian. The successive feeding activity of fleas on pets may elicit a hypersensitivity skin disorder known as flea allergy dermatitis (FAD). Treatment of pets with EctoShield™ Topical Solution Medium and Large Cat rapidly kills fleas and may reduce the incidence of this condition. EctoShield™ Topical Solution Medium and Large Cat is safe to use concurrently with commonly used veterinary products. Consult your veterinarian before using on animals receiving drug treatment.
