How a bead curtain works as a fly screen
Flies navigate mostly by sight, reading the light and shadow of an open doorway. A dense bamboo bead curtain breaks that pattern up, so the doorway stops looking like a doorway and most flies simply don't bother. Air, people and pets pass straight through; the flies, mostly, don't.
Why bamboo beats a mesh screen
A fitted mesh fly screen door means brackets, measuring and often drilling. A bamboo bead curtain hangs from two hooks above the frame in about two minutes, looks far nicer, and you can walk through it with your hands full. The weight of real bamboo also means the strands swing back into place quickly rather than tangling.
Will it fit my door?
Every curtain is 90 cm wide and 200 cm long, which suits a standard UK interior or back doorway, making it an easy door fly screen to fit. Hang it to clear the floor by an inch, or brush it lightly, for the best coverage along the bottom.
Does it keep every fly out?
Honestly, no — nothing does. But for houseflies, bluebottles and the rest, most of the time, a dense bamboo curtain is the difference between an open door you enjoy and an open door you regret.
