We don't have fleas, but we are surrounded by woods and field so we get plenty of ticks. I use K9 Advantix because it repels ticks and mosquitoes. When we used Frontline it would kill the ticks that bit, but it didn't stop the dogs from bringing them in. K9 Advantix really does repel the ticks and the dogs aren't bringing them in like they used to.
Now that I have an outdoor cat, I need to figure out what the best product for tick control will be for him.
