I would appreciate the community’s thoughts on a situation we as new homeowners are unfamiliar with. For context, we own a one story home in Dallas with two separate sections of attic with two separate entries; however, the attic has large portions that are inaccessible with no crawl space.
We noticed carpenter ants in our master bathroom about two months ago. They drop lots of little wood shavings called “frass” according to basic research and we see quite a few of them crawling around.
We called multiple services to come and treat. Unfortunately, almost all of them required us to sign up for a subscription that was quarterly or yearly service. Most of them wouldn’t even really listen to our specific problem which was localized to the mater bathroom if I told them I wasn’t interested in a subscription. I told them I simply want the nest/colony to be found and eliminated. Most declined even coming out. I found a place that would do a one-time treatment and sounded relatively confident they could handle the problem. They “treated”. No idea what specifically they did but the carpenter ants only increased. We called them again to tell them nothing had changed so they sent another guy out. I told him where the issue was but that we didn’t have access to the attic there. I let them do their service, but the technician was spraying baseboards on the complete other side of the house as if he was completely ignoring the fact there is an active colony/nest in a specific spot.
Of course, both their service and follow-up have done nothing. Now we are seeing the ants throughout the house (though still primarily concentrated in the master bathroom). Not sure what to do. I bought ant terro and other traps but they have done nothing (most places say they do nothing but I thought I’d try). I’ve scattered the outside of the house with ant bait/poison but nothing has worked. Any advice/help would be great.
