Borax works best. It's also very good for eliminating a flea infestation.
For ants, look for wherever they are marching in a line and place your remedy on that line, preferably near a corner/against a wall.
Pour ½ cup (100 g) of sugar and 1 ½ tablespoons (38 g) of borax into a jar,
then slowly stir in 1 ½ cups (350 mL) of warm water.[1] Mix until the sugar
and borax are completely dissolved and the mixture becomes a paste-like
consistency.[2] The water can be any temperature, but warm water helps
the sugar and borax dissolve better.
Alternatively, mix 3 parts sugar and one part borax together, then sprinkle
the powder across your doorway and window ledges. Carrillo says to “use
a duster to apply a thin layer,” or the ants will avoid it.[3]
https://www.wikihow.com/Kill-Ants-Using-BoraxMy results have varied depending on the type of ant. In general, I like the DIY version. The ants carry the borax/sugar paste back to the farm where others will partake, killing more of them than only surface treating with poisons. I put out the treatment in the morning, the ants have a party circling the bait all day, and by dark they've left the scene. I put out fresh bait the next day, and most times I get no return guests -- a good indication the party is over for them!
Terro works better on smaller ants IMO. Regardless, the treatment must be placed very low so ants can access it. I use waxed paper from flyers I get in the mail and insidevnewspapers. Terro has a variety of distribution methods including a squeeze bottle where you can disperse it on cardboard, paper, tile, etc. The plastic housing versions might be better if you have pets.
I was doing very well for the last 2 years having no real invasions. That changed this weekend after the neighbor tented his house for termites. The very next day, there was a large army of ants in in the kitchen! I predict the next termite swarming period will see them divert to my place as well.
If you search for borax roach killer, you'll see those products and DIY instructions overlap with ant killer. One solution for both pests.
