We have ants coming in from certain corners in our apartment, we keep fairly clean and tidy and have lived here for about 2 years before they started showing up.

Initially we thought they were termites however when I mentioned to the REA that there was a possibility it could be ants coming from another apartment she aggressively said it was our responsibility

We have tried multiple baits but the frass (ant poop) still pops up each morning. We are on the ground floor so either coming from another apartment or from outside.

Any tips will be greatly appreciated
