These ants recently invaded my house although I've seen them in the backyard for a while. These ants are very very fast and easily startle when I breathe over them. They come out both day and night. They seem to be black color with the naked eyes. I'm already having a hard time getting rid of grease/thief ants in the house for a while and now this second invasion. Help!
I would say, that it is a Nylanderia, but I am not very fit in ants from there. But iIf you could post your question Hyperlinks sind nur für registrierte Nutzer sichtbar, I think there's someone who could help you.
