Help! Ants keep trying to nest in my indoor plants and I can’t get rid of them. I take the plant outside and heavily water the plant to wash the ants out. Wipe the ants off the shelf and have tried ant traps and they just keep coming back. The ants are not tending any pests like aphids or scales and I spray the plant down with diluted isopropyl just in case. What can I do to get rid of the ants? Ants seem to really like the heart fern
