Many thanks Both. Judi where did you buy that bowl? It might just work unless one of the Terrorists decide to try and sit in it or drink the water.
Wolfie, I've used Maton outside the house and spray all around window nd door frames, which works. However, these are realky tiny and I have no idea where they are coming from. I also use the green traps from Mercadona and put them behind all the kickboards in the kitchen but it hasn't deterred them. The Cats bowls are now on top of the worktop, so no signs of these pesky ants this morning.
