10 Best Ant Baits 2026 in the United States

The TERRO T300-3SR Liquid Ant Killer is a popular choice for indoor ant control, especially effective against common household ants, including those attracted to sweets. It uses Sodium Tetraborate Decahydrate (a form of borax) as its active ingredient, which is a slow-acting poison that worker ants carry back to their colony, helping eliminate ants you rarely see. This makes it more thorough than sprays that only kill visible ants. The liquid bait comes ready to use in stations that are easy to place along baseboards, corners, or counters where ants often travel. You don’t need to do any complicated setup, so it’s convenient for most homes.

Being an indoor product, it’s designed for use inside the house rather than outdoors, where weather might affect performance. While borax is generally safe when used as directed, it should still be kept out of reach of children and pets. The bait’s effectiveness is usually noticeable within a few days, making it fairly fast-acting compared to some ant control methods. A potential downside is that this product targets sweet-eating ants specifically, so it may be less effective if you have ants attracted to protein or grease.

Since it works through ants feeding and sharing the bait, results can take a bit longer than instant kill sprays. This bait works best for indoor use against common sweet-seeking ants, offering an easy, low-effort solution that targets the whole colony rather than just the ants you see.

The TERRO T300B Indoor Liquid Ant Killer is a highly rated product that comes with 12 bait stations. It uses liquid bait with Borax as its active ingredient. This fast-acting solution is effective for a wide range of common household ants such as acrobat, crazy, ghost, little black, odorous house, and pavement ants.

The baits are designed for indoor use, making them suitable for placing along baseboards, in corners, and on counters where ants are commonly found. One of its main strengths is the ease of use; there's no setup required, just place the baits and let them work. The ants are attracted to the bait and carry it back to their colony, ensuring it kills the ants you see and those you don't. This provides a comprehensive solution to your ant problem.

However, it's important to note that this product is designed for indoor use only, so it may not be effective for outdoor ant issues. Additionally, while Borax is generally safe, it should still be kept out of reach of pets and children. If you are looking for a straightforward and effective indoor ant solution, the TERRO T300B is a solid choice.

The Ortho Orthene Fire Ant Killer1 is a granular outdoor treatment designed specifically for fire ants, including their queens, which helps tackle the entire colony rather than just visible workers. Its active ingredient is acephate, a common and effective chemical for insect control. This product is intended strictly for outdoor use, making it suitable for lawns, gardens, and around ornamental plants. It's very easy to use—simply sprinkle the granules directly on fire ant mounds without the need to water them in, which saves time and effort. Each 12 oz. bottle can treat up to 162 mounds, and the package includes two bottles, allowing treatment of a large area.

The granules begin working quickly, usually within an hour, so you won’t have to wait long to see results. Users generally find it effective against fire ants, which are notoriously tough to control. However, since it contains acephate, care should be taken to keep it away from children, pets, and water sources to avoid unintended exposure. This product is ideal for those dealing specifically with fire ants outdoors and looking for a fast, no-fuss treatment.

For broader ant problems or indoor use, other products might be more appropriate. Pairing this treatment with the Ortho Fire Ant Killer Broadcast Granules (sold separately) is recommended for optimal results.
