I used the glue traps because I have kids and a cat. They usually emerge around baseboards etc I think, so I put one trap near the back of the stove and one on the baseboard under the dishwasher.
The ants disappeared so I thought the traps were working, then they reappeared. Then they disappeared for good so something worked!
Ants don't like mint so if you want a natural solution to use in the kitchen, try dried mint. It can be messy but it works. I have used it to keep them away from the sugar bowl (now I keep the sugar bowl in the fridge if I have visitors who take sugar in their tea). I have also used essential oil of peppermint on a scrap of papertowel, pushed into corners where I thought they might be coming in.
If I see one running across the counter, I squish it with my hands (quickly, yuck!) I have become (nearly) immune to the yuck factor. I also use vinegar spray and make sure they don't get the news back to the nest.
Good luck with your problem. Hope your traps work.
