I have Carpenter Ants infesting my patio. They were there last year, and back again this spring. I sprayed a product called Natural Pest solution ant repel product around the perimeter of my home liberally. What a joke, $25 to feed the ants. They loved it.
I can't afford to redo the patio, yet the negative pitch providing a moist puddled environment is certainly what is providing their breeding ground.
So, I went outside and sprayed a section of the perimeter of my foundation where they like to gather with Windex, and they stayed away from the barrier. I also sprayed a couple of them with it and they struggled, then died within less than a minute of contact.
Is there a home made solution that you can recommend that I can spray my foundation walls with to repel C-Ants? I'm thinking of spraying the Windex, but I don't know how long this will repel them, because I do not believe it will have a residual/long lasting effect.
