There’s no single “best ant bait.” There’s the best bait for the ant you have. Pick a sugar bait for a protein-hungry ant and it will sit there untouched. This guide matches the common indoor ant baits to the ants they work on.
Short version:
- Small black or brown “sugar ants” in the kitchen: TERRO T300 liquid baits
- Ants ignore the sugar bait: Advion Ant Gel
- You want sealed stations (kids/pets): Combat Max bait stations
- Ants coming in from outside: add an outdoor perimeter bait
Why bait beats spray
Sprays kill the ants you can see, which are maybe 10% of the colony. The queen and the brood stay safe in the nest, and the colony recovers. Baits use a slow-acting poison that workers carry home and share, so the colony dies from the inside. For indoor ants, baiting is the approach university extension services recommend, and you should avoid spraying near baits while they work.
The comparison
| Bait | Active ingredient | Type | Best for |
|---|---|---|---|
| TERRO T300 | Borax 5.4% | Liquid (sugar) | Odorous house, Argentine, most “sugar ants” |
| Advion Ant Gel | Indoxacarb 0.05% | Gel | Wide range of species; ants that refuse Terro |
| Combat Max stations | Fipronil (check label for %) | Enclosed station | Homes with kids/pets; low-mess |
| Amdro / granular outdoor baits | Varies (e.g. hydramethylnon) | Granules | Outdoor perimeter, not indoors |
Always check the label on the package you buy. Formulations change.
Our picks
TERRO T300 Liquid Ant Baits
The default choice for the little ants trailing across your counter. Expect a swarm on the bait for the first few days. That’s the bait working. If it seems to fail, read why Terro sometimes doesn’t work.
- ✅ Very attractive to the most common kitchen ants
- ✅ Slow-acting borax gets shared with the colony
- ✅ Inexpensive, so you can place several at once
- ⚠️ Sugar-only, so protein-feeding ants may ignore it
- ⚠️ Can dry out quickly in warm rooms
Advion Ant Gel
Indoxacarb gel is a staple for pest control pros. Place pea-sized dots along trails and near entry points, never on surfaces you’ve just sprayed or cleaned with strong chemicals.
- ✅ Accepted by many species, including some that skip sugar baits
- ✅ Precise placement in cracks, behind appliances, along trails
- ⚠️ Costs more
- ⚠️ Small dots can be wiped up by accident, so place them out of the way
Combat Max Ant Killing Bait Stations
Uses fipronil. A good pick if you dislike open liquid baits or want something harder for curious hands and paws to get into. See our pet-safe ant control guide for placement tips.
- ✅ Bait sealed in a plastic station
- ✅ No liquid to spill or dry out
- ✅ Easy to tuck behind appliances
- ⚠️ Some ant populations take it more slowly than liquid baits
- ⚠️ Still a pesticide, so place it out of reach
How to bait properly (this matters more than the brand)
- Find the trail. Follow ants back toward where they enter: baseboards, window frames, outlets, the gap under the dishwasher.
- Put bait on the trail, as close to the entry point as you can.
- Use enough stations. One per active trail, minimum.
- Clean up competing food, but don’t wipe the trail with cleaners.
- No sprays anywhere near the bait.
- Wait two weeks. Replace empty or dried stations right away.
What about natural options?
Food-grade diatomaceous earth kills ants on contact by damaging their outer coating, but it only works while it’s dry and it doesn’t reach the colony. Use it as a barrier in dry voids, not as your main treatment. Vinegar and essential oils break up scent trails for a while but don’t kill the nest.
