Start looking at your baseboards like a detective. See that tiny gap where the wall meets the floor? To an ant, that’s a five-star entrance. A little tube of caulk costs less than a latte.
Seal up holes around pipes under the sink, too. It’s boring work, but it’s like locking your front door. You wouldn’t leave your actual door wide open at night, so why leave a micro-door for ants?
And check your window screens. A single tear is basically a velvet rope for a six-legged VIP. Patch it with a little clear nail polish in a pinch.
The Diatomaceous Earth Surprise
If the vinegar fails, bring out the big gun: diatomaceous earth. It sounds like a dinosaur bone, but it’s just a white powder that looks innocent. To an ant, it’s like walking through shattered glass.
Little Black Ants In House
Sprinkle a thin line near where they enter—like a tiny ghost fence. They walk over it, and it dries them out (gross, but effective). You can get it at any hardware store for pocket change.
Just wear a mask when you sprinkle it. You don’t want to breathe that stuff in. It’s ant-kryptonite, not a seasoning.
