I have flies in my flat. I only have one but as soon as I get rid of it, another one comes. I have stopped opening my windows and tonight I saw another one. I thought I saw one the other day but thought I was imagining it because my windows are kept closed which is a pity because I like fresh air coming into my place. I am now convinced that the fly I thought I saw the other day was a fly and this one tonight was the same one. Do the lurk and hide and then fly around when they want to because when I did not see it for a few days I thought oh good no more of these.
Can anyoen offer a solution. Pest control are not interested in helping me
