10 Best Ant Bait Killers 2026 in the United States

The TERRO T300B Indoor Liquid Ant Killer is designed for effective indoor ant control, featuring 12 bait stations and a fast-acting formula. One of the key strengths of this product is its ability to significantly reduce ant activity within days. The worker ants carry the liquid bait back to their colony, ensuring a widespread elimination of ants, including those not immediately visible. This makes the product highly effective against various common household ants such as acrobat, crazy, ghost, little black, odorous house, and pavement ants, particularly those that are attracted to sweet substances.

The bait stations are versatile and can be easily placed along baseboards, in corners, or on counters, allowing for targeted ant control in hotspots around the home. Additionally, the product is ready to use right out of the box, requiring no setup and making it very convenient for homeowners. The active ingredient in the bait is Borax, which is known for its effectiveness in killing ants but is also considered relatively safe for indoor use when used as directed. However, users should still exercise caution and keep the bait out of reach of pets and children.

One potential drawback is that while the product is effective, it relies on the ants taking the bait back to the colony, which might take some time and may not provide an instant solution. Some users might also find the sight of numerous ants attracted to the bait stations disconcerting before they are eventually eradicated.

The Ortho Fire Ant Killer Broadcast Granules offer a fast and effective way to protect your lawn from fire ants, killing mounds within 15 minutes and providing up to 6 months of protection. This product is designed as a preventive treatment to stop new fire ant mounds from forming by targeting flying queens. It covers a large area—up to 5,000 square feet—with a single 11.5-pound bag, making it suitable for medium to large lawns. The granule form is easy to apply using a spreader, and it requires watering in after application to activate the treatment.

This product works best as part of a two-step process: you first need to eliminate existing mounds with Ortho Orthene Fire Ant Killer before using these granules to prevent new ones. This could mean extra initial work and buying an additional product. While it targets fire ants specifically, it may have less effect on other ant species. Safety-wise, it is meant for outdoor use and should be handled with care, following label instructions to minimize environmental impact.

Customers appreciate its rapid action and long duration of effectiveness, which helps reduce repeated treatments. This product suits homeowners looking for a reliable, long-term fire ant control solution but who don’t mind first tackling existing mounds separately.

Raid Ant Killer Baits come as small, solid traps designed for indoor use, making them convenient for placing in areas like kitchens, basements, and pantries where ants commonly appear. The active ingredient, Avermectin B1 at a very low concentration (0.01%), works by being carried back to the colony by ants, targeting the queen and other ants to help eliminate the entire colony over time. This bait system lasts up to three months, which means you don't have to replace the traps frequently, and placing all traps at once can improve results. The child-resistant design adds a safety layer, making it a reasonable choice for homes with kids.

This bait is suitable for homeowners seeking a straightforward, low-maintenance solution to reduce ant infestations inside the home, while those dealing with multiple or outdoor ant problems might need to explore additional options.
