it's the time of year when ants come up through the added bit of our house, built right on the ground. With hindsight we would have dug a cavity between the floor & the ground.
I have an elaborate combination of ant poison, bicarbonate of soda (like a little castle), & then chilli flakes (looks pretty). The chilli and baking soda are deterrents from them coming further in to the room, the ant stuff is supposed to help actually get to the nest, but they come back every year. advice is welcome!
