Spring and fall brings ants to the homes of those of us in Kansas.
I have been ant free for over five years. My neighbors all have ants in their kitchen but I have not had an infestation in a long time. I will occasionally see one ant. . . I declare war and their surrender is immediate.
There are many natural products that will help keep ants out of your home. I used to use Raid and I would spray and spray until the ants were gone. I would put ant traps around my kitchen and in the corners. I would sprinkle the ant barrier around the house. Then I got a puppy and had a toddler that put EVERYTHING into her mouth. We stopped all of that immediately.
I will say that I don't do much about the ants outside. They're outside and they can stay outside. If you want to find out how to get them out of your yard, this isn't the post for you. If you want to find out how to keep them out of your house, keep reading.
First, clean up all your spills immediately. It's not just sugar the ants are after, it's grease, too. Dog food is greasy. Ants will be around your dog food bowls so pick them up after Fido is done eating. If you leave food out always, invest in a raised bowl and periodically pick up the chunks he drops if your dog is a messy eater.
Second, start using vinegar. Go buy a HUGE bottle of white vinegar. Get the cheap brand; you aren't trying to impress anyone. It will cost around three dollars. Wipe down all your counters and your floors with the vinegar (dilute with water, I go 50/50). Wipe underneath your sink with it. Don't like the smell? Turn it into citrus vinegar. Use orange peels; ants hate orange oil. You can also add peppermint or spearmint oil to the vinegar. They hate that, too.
Put some vinegar and water in a spray bottle. I go 50/50. Add your oils if you want. Spray around your door frames and window sills. Take a towel with you; these areas get dusty so you can wipe it off after you spray. You're cleaning and fighting ants all at once!
You can take your spray bottle outside, if you want. Spray around your doors and around your window wells.
Do you have ants on the carpet? Borax is your friend! Lightly sprinkle some Borax on the carpets. Keep your kids and pets off from it - be smart! I used to sprinkle it at the start of nap time and vacuum it up right after she woke up. You want to let it sit for at least ten minutes.
I was told that the vinegar destroys the ants scent trail. Keep using the vinegar until all the ants have found a new kitchen to stalk! It's worked for us for five years!
