Rats are very intelligent animals, and unless there are only a few of them that can be trapped out quickly, they will become trap wary. Traps that once worked will suddenly not be visited, they may be turned over or they may be soiled with urine and feces that tell other rats to keep away. When this occurs, the only solution may be a rat poison.
Poison formulas have come a long way since the early days of using toxic chemicals. Many are anticoagulants which, once ingested, cause internal bleeding. The rat goes into shock from loss of blood, feels no pain and succumbs. Care must be taken to hide the poison so that children, pets, and other wildlife don't consume it, and never distribute rat poison unless you are wearing gloves.
The poisons on this list were chosen because they are the most effective, easy to use, and affordable. Bait packs top the list because they keep the poison contained until eaten. That means safety first for children and pets alike.
The NEOGEN RODENTICIDE 40-Pack Havoc Mouse and Rat Killer is the most effective rat poison available. It is safely packaged so that rats must gnaw through it to eat, but the brodifacoum anticoagulant formula kills after one feeding. Read Full Review
The most effective, the easiest to use and the safest rat poison is NEOGEN RODENTICIDE 40-Pack Havoc Mouse and Rat Killer. The active ingredient is brodifacoum, which is a highly effective anticoagulant. In case of accidental poisoning, it responds well to the antidote Vitamin K. This poison is contained within a sealed package, and it is visibly marked as a poison. Rats gnaw through the package to get at the pellets. This method of distribution makes it safe to use, but it still must be concealed from children and pets for maximum safety. Rats will perish after one feeding.
The Neogen Rodenticide Havoc Chunks Bucket Rat and Mouse Killer are easy to place because of their block-like form. Distribute them on known rat runs for effective rat control after only one feeding. Read Full Review
Using the exact same formula as the Havoc 40-Pack Rat and Mouse killer listed above, the Neogen Rodenticide Havoc Chunks Bucket Rat and Mouse Killer is just as effective in an easy to use chunk block. The blocks are exposed so they must be completely hidden for safety, but rat runs behind cabinets or when dropped into holes are the perfect way to distribute these chunks. They are potent after one feeding, and Vitamin K is a highly effective antidote if ingested.

If you want safety overall, Tomcat Rat Killer ll with included locking bait station is a solid choice. Made of bromethalin, a substance that is toxic to the nervous system, once consumed, the rats central nervous system shuts down. There is no pain, and the rodent goes to sleep and never wakes up.
