Why am I seeing less activity on Final Blox Rodenticide than I saw with Contrac Blox?

I used contrac for 2 years. I purchased final last week. The mice are not eating up the final like they did the contrac. Can you give me some feedback regarding this? I have seen less drippings but a large amount of poison is still there.

Answer:

There are a few factors that may explain what you are seeing. First, different baits do have different food bases and different active ingredients, so sometimes one formulation is just more attractive to a rodent populaion than others. Another explanation - which sounds like what is happening here - is that the rodents are eating the bait you have put out, but you are just going through less bait. The active ingredient in Final Blox is more aggressive than that in Contrac, so it is very likely that the rodents will die before eating very much bait. Both Contrac and Final are single feed baits (the rodent only has to feed on it one time to consume a lethal dose), but since the rodents have more time to feed on Contrac before they die, we will sometimes go through more bait. As long as you are seeing the signs of rodent activity diminishing, then we would continue to monitor the area and supply fresh bait as long as you are seeing rodent activity.
