i have been trying for a couple of months to eradicate ants from my kitchen.
i can't see a nest, or any obvious place they could be coming from.
it started off with the odd one or two on the floor, the occasional one on the worktop.
i bought an ant killing spray, spray it liberally, wash my kitchen floor & work tops down with vinegar & water (i was told vinegar supposedly deters them), it seems like they're gone, don't see one for a few weeks.
then today, they're back. a horde of them on my worktop, the odd one on the floor, the final straw was opening one of my high-up cupboards & finding a couple trying to get in there. i even spied one running up the kitchen door!
my mum mentioned some gadget thing that supposedly gets them all within 6 days, but it was reliant upon you putting it near the nest/point of entry (& i can't bloody find it) so not sure it would work.
what can i do, is there any products you would recommend, it's driving me mad & it's giving me the major boak.
