How can I stop an invasion of ants in my kitchen?

I had an invasion soemhow they found their way into my kiitchen I used boric acid mixed with sugar it worked becuase I have not seen any more ants again

Either you are unknowingly putting them in the fridge when you put something in it or the rubber seal around the door is not sealing. Sprinkle Jiffy Muffin mix where you see ants and along baseboards. Ants cannot digest it. They take it back to the nest and it kills them. If they are really severe use some home pest spray and spray along baseboards.

Diatomaceous Earth in the house and around the perimeter of your house. It's good even if it gets wet.

You can try this, it's safe for children and pets. Some people scoff at this method, but I've heard it works.

I've heard cleaning the areas with Windex helps to repel ants.

I use packaged cornbread mix that says it is sweetened and put it where they are. They will take it to the mound, everyone will eat it and die, they can't digest the cornmeal, but will take it because it is sweetened. Little goes a long way.

I read this from : Itsmemic

Medicated powder from the Dollar Tree. It has eucalyptus in it...menthol...I puff it around my homes foundation..and inside under my birdcages in the cracks under moldings. Work immediately and they never come back. I do this at the first sign of ants..in one day..GONE. The powder is in a very large container and lasts quite awhile too !! And smells great !

Not toxic to my birds OR dog

What if you make a barrier around the house.

I did some research, since we know what works for one person doesn't always work for another. I found this site and it's pretty informative. I know some tips you may not be able to use but there are some good ones also that will hopefully help.

Ants are so weird. One time I found them inside the freezer in the garage!! What would possess them to go inside a freezer only to die? They must have sent signals back or something ~ there were no ant trails only a freezer full of dead ants. Hasn't happened since.

Hi Evelyn - Those little buggers are relentless, aren't they?!? This is the most effective method and all-natural spray DIY that we use with ants. It's best indoors, but will also work outside with more frequent applications. Hope this helps! Hugs, Holly

If you see ants, wipe them up with a solution of 50-50 vinegar and water, or straight vinegar. White vinegar kills ants and also repels them. If you have an ant problem, try using diluted vinegar to clean hard surfaces, including floors and countertops, throughout your home.
