You can fill small holes in metal screens with epoxy  Also, patch kits are often available at home supply and hardware stores; follow the kit instructions to repair the tear.  To patch a hole, cut a patch just barely larger than the hole. Apply a thin layer of fast-drying glue along the edges of the patch, and press it in place.  To avoid sticking fingers to glue, use low-tack painter’s tape to hold the screen together as it dries; cut a piece of tape larger than the patch, gently tape it to the patch, and leave until dry. To make your own patch for a metal screen, cut a patch from a length of screening. Trim edges of the hole into a neat square opening. Make sure the patch is 1/2 inch larger all around than the hole to be repaired; bend edges’ teeth into right angles. Set patch over opening so teeth penetrate the screen. Turn screen over; bend teeth flat on other side to hold in place
