Robait is an excellent product that attracts rodents better than any other attractant available. I have personally used it for over a decade now. Robait is unique in its ability to be distributed into an environment, where rodents can ingest it and become "hooked ". Once the rodent is "hooked " they will come to your trap baited with Robait, wherever you choose to place it. So you can place your traps in a convenient location for you to service them. Robait works Fast,many times I have caught an entire rat population the first night.
