How long does it take ants to die after being exposed to borax?

Ants typically begin to die within a few days after being exposed to borax. The timeline can vary depending on the species of ant and the amount of borax ingested. Generally, it can take anywhere from 24 hours to a week for the effects to manifest, as borax disrupts their digestive systems and leads to dehydration. Additionally, the slow-acting nature of borax allows for the bait to be carried back to the colony, affecting more ants over time.
