Ditrac is a multi-feed rodenticide (rodents would have to feed multiple times to build up a lethal dose) and can take 3-7 days for the rodents to die. The amount of bait you use will be based on the size of your infestation. You should keep a steady supply of bait available for as long as you keep seeing activity.
