10 Best Indoor Ant Killers 2025 in the United States

The TERRO T300B Indoor Liquid Ant Killer comes with 12 bait stations, making it versatile for placing around your home where ants are most active. It uses liquid baits with Borax as the active ingredient to attract and kill common household ants, including those you can't see. One of its main strengths is its fast-acting formula; you can expect a noticeable reduction in ant activity within days as it targets the entire colony. This makes it highly effective for long-term control of ants.

The product is designed to be user-friendly; there is no setup required, so you can simply place the baits and let them work. This ease of use is particularly appealing for busy households. However, a potential drawback is the safety concern if you have small children or pets, as Borax can be harmful if ingested. It's important to place the bait stations in locations that are out of reach of kids and pets.

Another consideration is that while it’s effective indoors, it might not be suitable for outdoor use. Additionally, while it kills the ants you don't see, this means you'll need to maintain the bait stations until the colony is entirely eradicated, which might require some patience. The TERRO T300B is regarded for its reliability and effectiveness for indoor ant problems.

The Hot Shot Pest Control Fogger is a convenient indoor solution for tackling heavy ant infestations, along with other pests like roaches and spiders. It uses a combination of active ingredients, Tetramethrin and Cypermethrin, which effectively kill insects on contact.

It's designed for use in various enclosed spaces such as homes, garages, and storage areas, and each can covers a substantial area of 2,000 cubic feet, making it suitable for larger infestations. Users have appreciated its non-staining formula, avoiding any wet, messy residue post-application. The fogger's effectiveness lasts up to 2 months, providing a long-term solution to pest control problems.

However, it's essential to note that this product involves the dispersal of chemicals, which may raise safety concerns for households with children or pets. Users should ensure the treated areas are well-ventilated and avoid direct exposure during and after application. The need for multiple cans (18 provided in a 6-pack) might be seen as excessive for smaller spaces. The Hot Shot Fogger is effective and easy to use for significant pest issues but requires careful handling to ensure safety.
