The only flea collar that appears to work well is the Seresto collar. And even then, I can have a slower rate of kill for the fleas. The top products on the market our oral products such as some Perica and next guard. For most pets, these are good options that I recommend to call your veterinarian first and doublecheck. Also, you will need to treat all the pets in the household for six months to make sure you get through the entire fleet lifecycle. Best of luck.

    I sent that message by mistake. The Seresto collar can have a slower rate of kill. The two best ora products are Simparica and Nexgard. You will need to treat all the pets in the house for an entire six months to get through the entire flea life cycle. Best of luck.*
