Mix Borax with honey (or a fat-based bait if ants target grease) into a paste, place teaspoon-sized dollops on cardstock near ant activity — Borax kills slowly enough that workers carry it back and collapse the colony, not just the visible ants.

Key takeaways

Borax kills the whole colony, not just visible ants — it acts slowly enough to spread

Borax kills the whole colony, not just visible ants — it acts slowly enough to spread

  • Borax kills slowly, so forager ants return to the colony and share the bait before dying.
  • This eliminates the source colony rather than just the ants entering your home.

Mix borax into honey until paste consistency; place ~1 tsp dollops on cardstock

  • Adjust ratio of borax to honey to achieve a paste — ants won't eat borax alone.
  • Refresh bait every few days; heavy infestations may consume a full placement within one day.

Match bait flavor to what ants are already eating, or they'll ignore it

  • Sugar ants → use honey or sugar; grease-seeking ants → use a fat-based bait instead.
  • Using the wrong attractant means ants won't consume the borax mixture.
