The label is really vague on this, it basically says to keep pets and livestock away from bait. The application rate is 1 lb per acre, so it is almost impossible for the horses to consume any large quantitiy unless they eat it directly out of the container. Here is a link to the label -http://www.epestsupply.com/labels/advion_fire_g.pdf
There really isn't a set time frame to keep them away, and since the ants usually it pick up the bait within hours, I would just good judgement.
