10 Best Indoor Ant Killers 2025 in the United States

The TERRO Ant Killer Bait Stations T300-3SR is a popular choice for those dealing with indoor ant infestations. Utilizing liquid bait, it effectively targets common household ants, especially those attracted to sweet substances. The active ingredient, Sodium Tetraborate Decahydrate (Borax), is known for its ability to kill ants by disrupting their digestive systems. This ensures the bait is lethal not only to visible ants but also to the entire colony, making it an effective long-term solution by reducing ant activity within days as worker ants spread the poison throughout the colony.

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 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. This product's standout feature is its ability to create a fine mist that penetrates deep into cracks and crevices, ensuring hidden bugs are also eliminated.
