Great ant ? ? invasion

We had a big problem with ants a few years ago, none of the sprays or liquids seemed to work, then we discovered the flattish, round ant stations sold at Wilko, and they worked a treat, in fact, haven`t had any problems since then.

I’ve had 2 invasions this year in different places luckily I spotted them pretty quickly. I have an aerosol ant spray I use across the doorway that they seem to use to come in. Once they are dead I clear them up and then disinfect where they’ve been then a good spraying outside the doors seems to stop them.
