Hanging Bednets: A Design Stuck in Time
Millions of people rely on a mosquito bednet whose design has not changed in 80 years:
The Humphrey Bogart classic film, The Maltese Falcon from 1941. This bednet is 85 years old. It is the very same design still in use today. What if the most effective weapon against malaria just needed a redesign?
How Hanging Nets Are Installed
A hanging bednet is basically a rectangular box of fabric that hangs from the walls or ceiling. The user ties 4 looped strings to the net and secures 4 nails or hooks to the walls (or the ceiling). Because the strings are a fixed length, users need to confirm the net fits the space before hanging. Once hung the net is spread over the bed or sleeping mat and the strings are adjusted to hold it tautly in place. As shown in this video - starting 45 seconds - this is not a one-person job. Even three people will find it challenging.
If users want to move it -- even just a short distance or to another room -- they must start over completely. For many families, that means a slow, frustrating process — or no net at all.
Every night, the net must be tucked under the mattress or sleeping pad — every edge, every corner. One unconscious shift in the night can open a gap — and that is enough for mosquitoes to enter.
Why Setup Is a Huge Problem
The traditional hanging design assumes every room has four strong walls, a flat bed and enough space to hang a large box of fabric. If the nails are too close or too far apart, the net sags or will not hang at all. In crowded spaces, installation is practically impossible. In shared rooms, repositioning the net means retying, rehanging and resetting everything.
Many people sleep outdoors. Without walls to hang from, the net collapses onto the sleeper's skin — and mosquitoes can bite right through it. If the net tears, there is no easy repair method.
These issues make consistent use nearly impossible , causing many to stop using hanging nets -- and leaving them unprotected from mosquitoes.
What a Redesigned Bednet Should Do
A 21st-century net should support itself without strings, walls, or hooks, keep fabric off the skin, seal automatically, and take less than a minute to set up.
Materials should be what they are now: insecticide-treated mesh fabric - which is very advanced technically and is improving frequently - and approved by the WHO.
The net should work on a mattress, floor mat, bunk bed, cot or emergency shelter—indoors and outdoors—with no nails, no strings, no guesswork.
In Summary
Bednets can save millions of lives -- but only if people use them. After 80 years, the traditional hanging bednet that millions rely on for protection needs a major redesign. If we can upgrade pens, phones, cars, lightbulbs and watches - almost everything - we can certainly upgrade the world's most important weapon against mosquitoes.
