I live surrounded by corn fields out in Winwick and the little beggars drive me barmy!!! They seem to love crawling up those hairs on the back of your neck just enough to irritate and has already been pointed out they get everywhere and somehow behind any pictures' pane of glass!!
Odd thing is they seem to all disappear around 7ish .... not sure if the temp drop causes them to go wherever but I can have hundreds crawling on the wall and 10 mins later none!! Very Strange!!
Think they should be stalked like they seemingly stalk me!!
