Rats and mice will not visit bait stations, regardless of their contents, if they are not conveniently located in areas where rodents are active. Where possible, place bait between the rodents' source of shelter and their food supply. Put bait boxes near rodent burrows, against walls or along travel routes used by the pests. Rodents usually will not go out of their way to find baits. House mice seldom venture more than a few feet from their nests or food sources, so place bait stations no more than 10 or 12 feet apart in areas where mice are active.
Rats are often suspicious of new or unfamiliar objects.
It may take several days for rats to enter and feed in bait stations. On farmsteads, bait station placement depends on building design and use.

Never place bait stations where livestock, pets or other animals can knock them over.
