Thank you Anne. I tried the lemon juice and the cinnamon both.
And that seems to be working. I've had ants other years and used ant buttons, which worked fine. But this year the ants are very, very tiny and I don't think they can even get inside those ant buttons. Raid Home & Garden works a bit but didn't stop others from returning. It seems to be under control since I tried the lemon and cinnamon. I'll know in the morning if that has cured the situation. If not, I will try the boric acid. Thanks again.
