How Do Flea Medications Work
How flea medications work will depend to a large extent on the type of active ingredient that they have. One thing that these medications share in common is that the active ingredient can repel or poison any insect that feeds on pets. The effect of flea medications can last from 1-3 months and are formulated to provide long-lasting and continuous protection against fleas. Spot-on medications are applied to the back of your pet’s neck where he can't lick it off. Tablets are usually flavored and chewy, making it easier to give to pets. Newer flea medications are now formulated to contain ingredients that are effective against other parasites, like ticks, lice, and mites. Some are also effective against intestinal parasites and heartworms. Since flea medications contain chemicals, they are potentially toxic to pets if the appropriate dosage is not given.
