We have a problem with carpenter ants. In the wooden ceilings dropping sawdust
in a few places in the house. All our neighbors had the same problems.
I have been making up and replenishing saucers of Boric acid and sugar
and water and see them eating from these.
I also spread spent coffee grounds around the base of the house and
pulled up most of the ivy touching the house.
Other than cinnamon, which I will also try, any suggestions?
Our landlord uses harsh chemicals that we would rather not live with.

    Most those harsh chemicals break sown in the soil to harmless constituents in a matter of days.

    What I'd do is keep up with the boric acid ( it works but it's slow) and try to track a column of ants. That'll take some doing. But, when you find the nest you can use the harsh chemicals on the little fukers and kill 'em where they live.
    They like old dying trees and stumps best-est.

    I had success with this combination (but with regular black ants -- two separate colonies):

    mix together
    peanut butter with grape jelly and boric acid (I forget the ratio)
    force some straws into the mixture
    place straws in areas where animals (esp. raccoons) won't have access to them

    Ants look for protein and sweets. I think I wrote about my experience in this tribe. Took about 2.5 days for the two separate colonies to trek in and out of my apartment and eat from the PJ&J&BA mix. Must've been thousands upon thousands of ants, as the stream was thick and steady -- saw even some queen ants -- until the trail diminished to just a few.

      I have had success with a bowl of molasses and sugar. I add in sugar until it is extremely thick. then i set it next to the and trail and just let them crawl in and get stuck. They crawl over each other until the top of the bowl is covered. Scrape em off and let it keep sitting there.

      I know the sweets and boric acid works for the little ants, but does it also work for carpenter ants?

      I didn't think they were attracted to the same bait.

      That would be nice if they were.

        The carpenter ants feed regularily at our saucers filled with the boric acid acid,
        sugar and water brew. It is a long process and the numbers are dwindling.
        we just discovered a heavily traveled pathway to our house in the power lines.
        I got some of that gooey paste you use on tree bases to keep ants off for the power lines.
        I will put out little bowls of uncooked grits for them too.

    Well biggest issue is finding the queen. If it is in the attic you need to find the material they have infected cut it out and replace it. I treat the timbers with copper sulphate <very mild and will not be a problem behind drywall. The other thing they need is a source of water. Make sure you have no leaky pipes.

    Clear all vegetation away from the foundation. This also includes woodpiles ect. They also frequently walk up the walls behind the siding to access harder to get to boards. The little sawdust piles are a good hint as to their entry point.

    Chances are if they have been at it a while there is some extensive inwall damage

    Goodluck

      JSin is exactly correct.

      The water the ants harvest is used to rot the wood. They can harvest water from pipes that are merely bare inside the walls. Humidity around cold water pipes gives rise to condensation build up on 'em and the ants will harvest it from the pipes. Leaky toilets and faucets are the number one cause of this.
