10 Best Carpenter Ant Baits 2025 in the United States

The TERRO T300B Indoor Liquid Ant Killer is a widely popular choice for addressing ant infestations inside the home. It uses Borax as the active ingredient, which is effective in eliminating ants by allowing them to carry the bait back to their colony. This approach ensures that even hidden ants are targeted and eradicated. The formulation is a liquid, which is generally more attractive to ants, especially sweet-eating varieties like acrobat, crazy, ghost, and little black ants.

Users have reported a noticeable reduction in ant activity within days, which speaks to its fast-acting nature and effectiveness duration. The product comes with 12 bait stations which are easy to place around the house in areas such as baseboards, corners, and counters without any complicated setup, making it user-friendly. Safety is a consideration, especially in homes with pets and children, as Borax, while effective, requires careful placement to avoid accidental ingestion.

One potential drawback is that it is specifically designed for sweet-eating ants, so it may not be as effective for other types of ants. Additionally, since it is an indoor solution, it doesn't address outdoor ant issues. The small size and lightweight nature of the bait stations make them convenient to use and store. This product is best suited for individuals dealing with common household ants indoors who are looking for an easy-to-use and effective solution.

The BASF Advance 375A Granular Ant Bait is designed to target a wide variety of ants, including carpenter ants, making it a versatile choice if you’re dealing with multiple ant species around your home or lawn. It uses a low concentration (0.011%) of abamectin as the active ingredient, which works slowly to let ants carry the bait back to their colony, effectively spreading the treatment and killing more ants over time. The granular form comes in different grit sizes, helping many kinds of ants pick it up easily.

This product can be used both indoors and outdoors, offering flexible application options—you can apply it in bait stations, around the perimeter of your house, or directly on ant mounds. This makes it practical for treating ants in various settings such as homes, hotels, or lawns. Since it is toxic to humans, pets, fish, and wildlife, it is important to follow the label instructions carefully to stay safe.

Ease of use is good due to its ready-to-use format and multiple ways to apply it, though caution is necessary to avoid unintended exposure. If you need a strong, ready-to-use bait that targets many ant species including carpenter ants, this product provides a reliable solution. Be mindful of safety precautions when using it around children, pets, or wildlife.

Advion Ant Gel Bait is a convenient and effective option for controlling carpenter ants and other common ant species both indoors and outdoors. Its active ingredient, 0.05% indoxacarb, is a powerful but non-repellent chemical that ants don’t avoid, which helps ensure better bait uptake and colony elimination. This gel formulation is odorless and can be applied precisely into cracks, crevices, and other hard-to-reach spots where ants hide, making it fairly easy to use for most homeowners.

The bait specifically appeals to sugar-seeking ants, covering a wide range of species including carpenter ants. Designed to minimize risks to people and pets, the product targets ants rather than non-target insects. Users have noted its quick action and lasting control, helping keep ant problems at bay for a significant period after application. The gel comes in compact syringes that are easy to store and handle without mess.

While effective against many ant types, careful placement of the bait enhances results, and consistent monitoring is advised to detect any new infestations early. Like most bait products, full colony elimination may require some time, so patience is necessary when using the gel. This product represents a strong choice for those seeking a user-friendly, targeted solution for carpenter ants and other ant issues around the home.
