We have better luck with the Tomcat bars, and like the rest of you, we really go through them this time of year. The Hawk bars are also green with a little different texture and color, but for some reason they don't seem to work as well for us.
Dogs love all of the bars, so be sure to use them in a bait station or keep an eye out for them if you think you have put them in places that dogs can't get to. Sometimes rats will pull them out and leave uneaten chunks that dogs can get at.
Never had much luck getting them to inadvertently accidentally eat the Rozol, Martins, Kaput, or any of those gopher baits. Very unfortunate that Traveler has to put up with those darn rats and mice getting into the bait that he keeps specifically for other purposes.
