Ants in my house!

[Cookiemonster]

Hello all,

I grow indoors, and recently have found some of my plants next to a window with ants- on the new growths with the sticky sweet sap. I have checked for aphids and nothing- I have been spraying every morning just incase with Safers insecticidal if there are any aphids- still no buggers, but I am finding the ants crawling on the new growths- i think they want that sugar-
I want them gone!
Is there anything I can spray indoors that is safe for me? Would it be safe to spray them outdoors with bayers rose& shrub stuff and bring the plants inside when they're dry.
Thanks
