i just got a pif paf spray it sprays automatically every 15 min and lasts for 4 weeks and is meant to prevent ants and cockroaches etc as ive had annoying ants in my new villa.... i leave alot of powder down that controls them abit but got the spray yesterday and have had alot less ants today so i think its working... U can get it in spinneys or c4.
ACE had some gel traps and spray, but you need to make sure it goes directly into the nests and follow instructions. The trick is to find the nests and kill them, very hard.
Very hard to totally get rid of. You can put ant powder in the top of the nest so that any ants coming in or out will take the powder wherever they go. Put powder inside your sliding doors to stop them coming inside, especially in the winter when it's damp and going to rain, they seem to know and come inside eurgh!!! Apart from that not a lot really. Good luck, you seem to hate them as much as I do.
