About this item
- Kills the entire colony, not just visible ants — the borax is slow-acting, so workers carry it back to the queen
- Pre-filled, ready-to-use — no setup time, just snap the tab and place
- 3-pack format works out to ~$1.08 per station vs ~$0.91 buying singles — buy the 3-pack only if you’ll use all 18 within ~2 years
- Made in USA, EPA-registered (Reg. No. 149-8), 50+ year-old product line
- 4.6★ across 150,000+ Amazon ratings — among the most-reviewed pest products on the platform
- Plastic station design is sealed — much less mess than gel-bait alternatives
- Works on most common household ants: sugar ants, odorous house ants, pavement ants, Argentine ants, ghost ants
