What is the best way to kill black ants inside a house?

I’ve been dealing with black ants since 3 month. They showed up in March and would not leave so we decided to buy ants killing medicine in our house. It helped kill the ants and a few spiders but about 2 days after that they started showing up again.

Please if you have any recommendations on spray/traps/homemade traps or anything else please let me know! I can’t take these ants anymore.

Hi Swity,
I shall try to solve your problems by suggesting. Please try any of this method.

Get some food-grade diatomaceous earth, available at garden center, and, of course, the internet. The link below goes into detail how it works. And, it works! It will kill ants as well as deter them, and no toxic chemical can do that. So safe for humans and pets, you can it eat or even dust it deep in their coats to help control fleas.

Sprinkle around trails, areas where you see them, and round the perimeter of your home. The thing is, you need to find out where they’re coming in, or nesting, and focus on those areas. Even hospitals (!) get ant infestations, so don’t feel as if you’re doing something wrong or attracting them. One thing I would be concerned about is that they are carpenter ants. If they are, then you need to determine where they are nesting as they can seriously damage wood, and focus on those areas. If they appear to be coming from the sink area, they might be using your pipes as a highway to your kitchen.

The magic doesn’t happen overnight, but it does happen. You’ll start to see fewer and fewer ants until maybe just a rogue one wandering around. I have a small organic farm, diatomaceous earth is all I use to control creepy-crawlies, and it is very effective when used as directed.

2nd method 

You can Use cedar oil and water mixture 50-50 and spray around windows and door openings. It will kill the ones it lands on, and repel others from entering for months. Non-toxic to animals and humans, but repels ALL INSECTS. Not to be used directly on tiny animals such as hamsters, gerbils, mice, etc. but safe on all pets, people, etc.

3rd Method 

In this method, You need to spray outside to keep them from coming in. Spray the perimeter of your house and make sure that all connections in (plumbing) are caulked and sealed.
It’s essential to remove their food sources. Make sure everything is sealed and keep the pet food up and away unless it is feeding time.

Thanks for you questions.
