I have used your products in the past, most recently using a great paint additive that worked on my home’s exterior trim and cedar barnsiding to repel insects, bees, etc. I am now confronted with a problem with carpenter ants and need some advice.
A few years ago carpenter ants entered through a second floor bedroom window sill and the company that monitors my Sentricon system drilled holes in the drywall beneath the sill and dusted. Since that time I have observed one or two stray ants in that area; however, this week the same thing happened in another bedroom on the opposite side of the house…should I have that same treatment repeated there? Do you have any suggestions for me or products that I, as a homeowner should be using? I asked the representative if, while painters are here doing interior painting I should just have the drilling and dusting done throughout the second floor beneath windows and I was told not to and that the dusting only lasts 3-6 months…I am now at a loss because painting is expensive and drilling, dusting, then repainting is costly…please advise about any outdoor and indoor treatments I can pursue…thank you!
If you read through our CARPENTER ANT CONTROL ARTICLE, you’ll learn this ant tends to create several nests which “network” together thus forming one super colony. So though it sounds like you were able to get one nest some time ago, it no doubt had links to other nests which are now sending in support to try and reconnect. At this point they’ve either established a nest on your home or will if you allow them to go about their travels untreated.
Based on how many you’re reporting, I don’t know that dusting will resolve the level of activity you’re seeing. As our article explains, this approach is best only when you’re sure there are ants in the void you’re treating. And if in fact they were in any of these other window sill areas, I think you’d be seeing a lot more activity. No doubt DRIONE would be the product to use if this was happening but again, I don’t think that treatment will help the best for what’s happening now.
What should be done is a perimeter treatment using TERMIDOR and PHANTOM. Simply spraying the foundation around the outside of the home will have a big impact. Any ants walking over the treatment will bring the active back to their nest which in turn will kill the colony. This means you’ll be able to get these satellite nests without having to know exactly where any are located.
If you’re seeing any ants inside the home, use the Phantom along baseboards and other areas they’re active. It’s odorless, goes on dry and won’t make a mess when used properly. It works just like the Termidor but is best suited for use inside. A combination of these two products will no doubt take care of these ants whether they’re nesting in the home now or trying to create a new nest.
