Each year I have a problem with ants in my kitchen, and each year I use an ant killer. (I actually hate killing them, and never kill them in the garden). However I'm having a new kitchen fitted and the builders have just pulled some boarding off the wall, and there are thousands and thousands of ants. How can I get rid of them permanently? PS they also come up into the bathroom which is on the ground floor and in the MIDDLE of the house - no outside walls. PLEASE help.
We had a problem with ants in the kitchen. Rather than put down ant powder we bought "ant stop, bait station" a round device from Tescos about 3" diameter which contains poison. They enter through a hole in the device and take it back to their nest. They last for about 3 months. Since then we have been clear of them.
Yes. You need to get rid of the Queen ant, and the way to do that is to put down poison "food" that the worker ants will take back to the nest to feed to the others including the queen.
You can buy Ant Bait Stations from garden centres and good hardware shops. They're plastic disks which contain poisoned bait which the ants love, take back to their nests and it kills them all. Very effective and much better than having to spread messy ant powder all over the place. Just notice that rov1200 has already posted about this. These products are very effective and totally solved our ant infestation.
