This product works so good. Its really hard to beat. Seems to work better than some blocks I tried. However in one farm shed the havoc xt blocks are being eaten by the field mice and rats that come in it pretty good. I put a few of the Blocks and a few of the Resolv packs in each box. Qne box they ate about equal amounts of each product. Usually more often the resolv will be eaten in most locations.
I read as much as I could about the many ways to kill the little furry creatures that tear up my landscaping from underground. I decided to get a pail of this stuff because of the convenience of the packs. I haven't seen a single new mound of dirt spring up or a single furry critter run across my yards since dispensing these packs about.
I had rats so bad in my barn, and this eradicated them and days. I also have dogs that were near it, but was told that this is non-toxic to pets unless they eat about 20 tablets of it. It's been three weeks. I have no rats and all my animals are fine. It was suggested to me by a friend and because I live in a country Where rodents always become a problem I will always keep this one stocked.
