There are several ways to kill carpenter ants, including using insecticides, baits, and natural remedies. Here are some methods to get rid of carpenter ants:

1. Insecticides: Using an insecticide that contains pyrethroids is the most common way to get rid of carpenter ants. The key is to get the insecticidal spray or dust into the nest. One good non-repellent spray for carpenter ants is Termidor SC.

2. Baits: Baits can be used to help kill off the population of carpenter ants. A combination of bait and a time-release pesticide is effective. The bait will attract the ants, and the pesticide will kill them.

3. Natural remedies: There are several natural remedies that can be used to kill carpenter ants. For example, mixing water with dish soap in an empty spray bottle and spraying it onto the affected area in your home can be effective. The solution is harmful and toxic to the carpenter ants, so it works well. Another natural remedy is to use diatomaceous earth or boric acid, which are non-pesticidal ant killers.

Its important to note that prevention is always the best form of pest control. Keeping your home clean, particularly the kitchen, flooring, windowsills, and countertops, can help prevent carpenter ants from entering your home.
