I have large black wood ants nesting in my door frame. The back door of my house started to have saw dust fall from the frame and when I took a closer look, I spotted several large black ants run into the crack between the molding and the wall of my house. I know they’re living in there and want them gone as quickly as possible. I haven’t done anything yet but figure there should be a good spray to use. What would you suggest?
Wood ants are what we call carpenter ants. Though they don’t eat wood, they can chew through it and commonly will do so when making a nest. I suggest you read our on line article on WOOD ANT CONTROL to better understand this pest and what you should be on the lookout for to make sure they don’t make nests in other parts of the home.
As you’ll learn from our on line article, this ant loves to nest in small voids or spaces like the location you’re seeing them at now. To treat such locations thoroughly, the use of some DRIONE DUST is most appropriate. It will do a great job of penetrating all the spaces where they might be and will quickly kill them all. I suggest you also spray the outside of the building with some SUSPEND to make sure there aren’t other nests close by that can continue to thrive.
