I thought I'd cured the problem. On Saturday night I went into our conservatory and it was like a horror scene - the place was alive with flying ants. We were on our way out so I shut up the house and by the time I went down on Sunday morning most were gone. I quickly sealed where I thought they'd been coming in (where the glass meets the wood frame and where the wood frame meets the tiled floor) and that solved it for a couple of days but today they are back again. There is a mixture of flying and normal ants. I've seen them on the patio and imagine they must be living under the pavers.
Will B&Q have stuff to get rid of them? I was reluctant to use poison (I have 2 cats and dog) but I can't litterally re-seal the entire conservatory pre-empting where they might get through again.
Anyone have any flying ant/ant experience?!
