Does Terro Kill Carpenter Ants?

Ants 1

In the battle against household pests, one product often comes up in conversation: Terro. Known for its range of pest control products, Terro is a popular choice for those looking to eliminate unwanted intruders. But when it comes to one specific pest, carpenter ants, does Terro live up to its reputation?


Yes, Terro does kill carpenter ants. The brand offers specific products such as the Carpenter Ant & Termite Killer spray and liquid ant baits that are effective against carpenter ants. However, the effectiveness can vary depending on the ants’ feeding cycle and the proper application of the products.

What is Terro?

Terro is a brand that offers a suite of pest control products, including sprays, granules, and most notably, their liquid ant baits. The brand’s products are designed to eliminate a variety of pests, from ants and cockroaches to spiders and other insects.

How Does Terro Work?

Terro products, particularly their liquid ant baits, work through a combination of borax, sugar, and water. This combination attracts ants that consume common sweets such as syrup, honey, jelly, sugar, and fruit. The borax in the bait interferes with the ants’ digestive system, killing them slowly.

This slow death allows each foraging ant to make several trips to the bait, delivering the toxin back to the colony, and eventually eliminating it. However, it’s important to note that this method’s effectiveness relies on catching carpenter ants during a phase of their feeding cycle when they are actively seeking sweets.

Terro Products for Carpenter Ants

For carpenter ants specifically, Terro offers the Carpenter Ant & Termite Killer spray. The spray uses Deltamethrin, a synthetic pyrethroid insecticide, to kill carpenter ants, termites, and other pests on contact, providing residual control for up to four months.

In addition to the contact killer, Terro also offers liquid ant baits that can be effective against carpenter ants under certain conditions. If the ants are in a feeding cycle for sweets, the liquid ant baits can successfully eliminate the colony.

How to Apply Terro Products

Using Terro products effectively requires proper application. First, identify the infested areas. Then, prepare the product for use. If using the Carpenter Ant & Termite Killer spray, ensure the nozzle is in the “on” position. Spray the infested areas until slightly moist, and treat any ant hills and trails as well. Monitor the areas and reapply as needed. When using indoors, apply the product in areas where pests tend to crawl and hide.

Potential Drawbacks and Risks

While Terro products can be effective, there are potential drawbacks and risks. The liquid bait can cause colony segmentation if used in the wrong ant hills. Spillage is also a risk, particularly around children and pets. Additionally, the bait may not consistently attract carpenter ants, and other treatments may be necessary.

Comparing Terro to Other Ant-Killing Products

When compared to other ant-killing products on the market, Terro holds its own. It has a solid reputation, with many positive reviews and recommendations. However, its effectiveness against carpenter ants can vary depending on the ants’ feeding cycle and preference for sweets.

In conclusion, Terro can be an effective solution for dealing with carpenter ants when used correctly and in the right circumstances. A combination of Terro Liquid Ant Baits and Carpenter Ant & Termite Killer spray can provide optimal results for controlling carpenter ant infestations. However, as with all pest control methods, continued monitoring and treatment may be necessary to fully eliminate the problem.
