9 count (3 x 3 ct) Sentry FiproGuard Plus IGR Flea and Tick Control for Large Dogs

Sentry Fiproguard Plus IGR Flea & Tick Control combines the pest-killing power of fipronil with a powerful IGR (insect growth regulator) to break the flea life cycle and provide fast, effective pest treatment. It remains effective even after bathing, water immersion, or exposure to sunlight.

• Kills fleas, flea eggs, ticks and chewing lice
• Breaks the flea life cycle
• Insect growth regulator kills eggs and prevents pupae development
• Remains effective after exposure to water or sunlight
• For large dogs 45-88 lbs (over 8 weeks old)

While fipronil kills and repels adult fleas, ticks and chewing lice, the IGR novaluron kills their eggs and larvae and prevents pupae development. Fiproguard Plus IGR kills adult fleas for up to 3 months, and ticks for 1 month.

Kills: All stages of brown dog ticks, American dog ticks, lone star ticks and deer ticks that may transmit Lyme disease. Fiproguard Plus IGR is recommended where tick and lice control is needed. Apply monthly if your dog is at high risk of flea reinfestation. Do not use on cats.
