This is War!

My wife use a special chalk aside from spray. I don't know this kind of ants why they always coming to our house and find for food.

Like one of the responders, i like to use special chalk that have been mixed with anti-ant chemical. I usually draw the chalk on the legs of the table, so ant couldn't go near the food. Sometimes i still see ants in my house, but none of them go near my food because of the chalk.

I had that problem in my last place and the exterminator came to fumigate. We were moving a week later. There are no ants in the new place where I am living now.

Leave out a bottle of maple syrup, the kind with the plastic top that has a hole in it for pouring. Make sure it is about half full and don't close the cover. The ants crawl in because they smell the sugary syrup and then fall in and drown. This is a good way to direct the ants away from the rest of your food while you wait for them to find the ant bait traps and carry the poison back to the colony. However, different kinds of ants behave differently, so always research the right bait or poison for the type of ant you have. If they are the large carpenter ants, their nest is most likely outside and they have ways into the house, where they chew on wood that is soft from moisture or rotted and find ways into your kitchen. Usually, the entry point will be near a sink or other water source.

We had that problem for a while, but now the ants and the mice spend all their time and energy on fighting each other and leave us in peace. Well, it would be peace if we could convince our younger dog to stop barking instructions to the ants. Lash

We get invaded every year. I used to use a borax and sugar mixed in hot water, then dip strips of paper towel in and put in strategic places. Borax is the main ingredient in most ant poison. This year we had the tiny ants that came in and the extra large carpenter ants outside. I think they were from the same colony. The borax didn't faze them. I tried all kinds of ant poison. No help. I was so frustrated and angry. They were all over the dog pen. Can't poison the dog pen! I just lost it one day. I started filling buckets with soapy water and pouring over them. I poured it over the dog houses, all over the patio (they had a trail there that even bleach wouldn't keep them from using), lifting the dog houses and soaking underneath. I went through an entire container of dish soap, refilling that bucket. I knew water wouldn't slow them down. I tried drowning them before. I was just so angry, I wanted to do something to harass them like they were doing to me. It actually worked! No more ants in the house. No more ant mounds in the pen. Well, there were still ants there. But it wasn't like before. They weren't covering everything like a living mat anymore. Hey, dish soap is cheap. I used Dawn that time. I "washed" the remaining ants a week later, with Palmolive. They didn't like that either. I can even use it in the chicken pen. The stupid chickens won't eat ants. But this has cut down on the population extremely well.
