I have peonies planted in the front of my house. Every year for the last several years when they are getting ready to bloom I've had a problem with ants in the house. This year I started seeing them around the front door so I set out an ant trap. No ant problem in the house but no peonies either.
They've looked like this for about a week now. I think I may have spotted one or two stray ants the other day on them but that was it.
Maybe I should just move them to the back of the yard so they're far enough away from the house that I won't have to worry about the ants coming in.
