We've been battling ants in our kitchen for the last few weeks.
I thought I had got rid of them with putting down Nippon liquid over few days on pieces of card. One night a load of them were feeding on them, and in the days that followed, ant activity significantly dropped. but it didn't stop entirely. There was always one or two stray ants wandering around somewhere, and I would sweep them up and put them outside.
But this has continued for the last couple of weeks - despite me putting down fresh Nippon every couple of days or so. Now they seem to walk past the poison and not go near it, let alone eat it!!! Are they immune to it now??
What can we do??
