16-ounce spray bottle of Zodiac Flea and Tick control spray. It can be used on dogs or cats, kittens or puppies, and offers two month protection against fleas, ticks and even mosquitoes. My dogs absolutely hate this stuff. Buddy runs out in the yard and rolls in the dirt over and over trying to get it off. We tried the Sentry Pro flea and tick spray once and they hate it too. I don't use this spray often. It's toxic as hell and in order to be really effective you basically have to drench your dog in it (I'm exaggerating only a little). This could be considered one of the last lines of defense in the flea battle. We only go here when a flea has actually been sighted.
