Back in the Skalitsa farmhouse we have now a swarm of ants that had invaded the sitting room. tis didn't happen last year. As I surveyed the front of the house, they had access through a previously cemented and sealed gulley as the bottom of the wall. they had systematically made holes in the cement and this now will have to be re-cemented to stop them coming in again. Looks like this will have to be done every two years.
