How many ant baits do you need and where to place them?
How many ant bait stations to buy and where to place them — by infested rooms or m² and infestation level, plus a natural DIY option.
Quick answer
Plan about 2 bait stations per infested room — or 1 every 8–10 m² of the affected zone — then multiply by infestation level (×1.5 for active trails, ×2 for a full invasion). Example: a kitchen plus a bathroom with steady trails → ~6 stations (2 rooms × 2 × 1.5), rounded up to whole packs (usually 4 per box). For gel, place a pea-sized drop every 30–50 cm along the trail.

⚠️ General quantity guidance, not pest-control advice. Follow the product label and keep baits out of reach of children and pets. Do not spray insecticide near the baits. For large infestations or carpenter ants in wood, call a professional.
Estimate: ~2 bait stations per infested room (×1.5 active trails, ×2 invasion), or ~1 every 10 m². Gel: one pea-sized drop every 30–50 cm along the trail. Place on the trail and at entry points, never where you clean with detergent.
How it works
Placement beats quantity: put baits right on the trail and next to entry points — skirting boards, cracks, under the sink, behind appliances — never where you wipe with detergent, which erases the scent trail. ⚠️ The number-one mistake is spraying insecticide near the bait: you kill the workers before they carry the poison back to the nest. Leave them alone for a few days — seeing more ants at first is normal and means it is working. Ready-made ant bait stations and ant gel target the nest; for a natural route, diatomaceous earth dusted into cracks works mechanically.
The moment most people throw the bait away is the moment it is working. These products are designed to be slow: the ants have to carry the poison home and share it before it acts, so a station crawling with ants for two or three days is exactly the intended behaviour — an instant kill would take out the foragers and leave the colony to send more. Resist spraying anything near the trail while the bait is out; you would be killing the couriers. Expect the traffic to build for a few days, then thin out, then stop, usually within one to two weeks.

Frequently asked questions
Where should I place ant baits?+
Directly on the visible trail and at entry points: along skirting boards, near wall cracks and window frames, under the sink and behind or beneath appliances. Put baits both low and high if ants climb the walls. Keep them out of reach of children and pets, and away from surfaces you clean with detergent.
How many metres apart should baits go?+
Roughly one bait station every 2–3 metres along an active trail, plus one at each entry point you can find. Gel is placed more densely — a small drop every 30–50 cm. More baits on the trail beat scattering them randomly around the room.
How long do ant baits take to work?+
Usually 3–7 days for a small colony, up to two weeks for large ones. Activity often spikes at first because workers keep feeding and carrying the bait to the nest — that is the goal. Do not remove or spray the trail during this window; let the colony take the bait home.
Bait, gel or spray — which is best?+
Baits and gel eliminate the nest because ants carry the poison inside; that is what actually solves the problem. Sprays only kill the ants you see and, used near a trail, are counterproductive — the survivors just reroute. Keep spray for an outdoor perimeter barrier, not on indoor trails you are baiting.
