A removable insect screen 1 adapted to be received in a window or door frame comprises a central passage 3, attachment means 5 adapted to contact at least one inner surface of the window or door frame and a screen 4 which is positioned within and substantially fills the central passage. The attachment means may be moveable between a first position, in which it is housed within the frame, and a second position, in which one or more retaining elements protrude from the frame. The retaining elements may be biased towards the second position and the screen may be formed from a porous or mesh material. |
