Do fleas and ticks need to bite my pet to be killed by FRONTLINE PLUS ®/FRONTLINE TRI-ACT ®/FRONTLINE ® SPOT ON?

Answer

No. FRONTLINE PLUS®, FRONTLINE TRI-ACT® and FRONTLINE® SPOT ON act topically, which means that fleas and ticks are killed through contact with your pet’s skin and coat – they don’t need to bite to be killed.
