Hartz Flea & Tick Collar

I used to use these when I lived in Wisconsin. They did help a little, but I still found fleas and ticks on my dogs. They seemed to offer the best flea and tick control around the collar, which I guess makes sense. I have switched to topicals since I moved to Florida and had much better results. These were inexpensive and easy to use, but with the fleas and ticks in Floria, I need something more effective.

Pros: easy to use

Cons: didn't work well

I wanted to save some money by buying this, but ended up spending more. This collar does not work as it's supposed to. There were no fleas around the cat's neck, but they were everywhere else in the fur. So what's the point?

Pros: Pretty colors

Cons: No effect
