As the British summer finally arrives, so does the inevitable swarm of pesky flies invading our homes. But before you reach for expensive chemical sprays or futuristic gadgets, a solution might already be sitting by your kitchen sink.
Experts have revealed a remarkably simple and cheap trick using a staple found in almost every UK household: washing-up liquid. A few drops of a brand like Fairy Liquid, combined with water in a spray bottle, can act as a powerful and natural fly deterrent.
Why This Simple Hack Works So Well
The science behind this method is surprisingly straightforward. Flies are equipped with complex respiratory systems and are highly reliant on the surface tension of water. Washing-up liquid is a surfactant, meaning it breaks down that surface tension.
When sprayed directly onto a fly, the soapy solution effectively suffocates the insect by clogging its spiracles (the tiny breathing holes on its body). It also damages the fly's exoskeleton and weighs down its wings, preventing escape. For those who'd rather not kill them, a light mist around windows and door frames acts as a powerful repellent barrier that flies are keen to avoid.
How To Make Your Own Fly Repellent Spray
Creating this effective pest control solution takes less than a minute:
- Grab a clean spray bottle – an old cleaning product bottle is perfect, just ensure it's thoroughly rinsed.
- Fill it almost to the top with water.
- Add a generous squeeze of washing-up liquid – roughly a tablespoon is plenty.
- Gently swirl the bottle to mix – avoid shaking to prevent too many suds.
"A simple spray made from washing-up liquid and water can be a highly effective tool against flies," confirmed one pest control expert. "It's a safe, affordable, and immediate method that doesn't involve harsh chemicals near your food or surfaces."
A Natural and Cost-Effective Alternative
This hack highlights a shift towards natural, DIY solutions for common household problems. With a bottle of own-brand washing-up liquid costing as little as 30p, it presents a fraction of the cost of commercial fly sprays, electronic zappers, or professional exterminator calls.
So, the next time a fly buzzes past your ear, you know exactly what to do. This humble kitchen hero isn't just for cleaning plates—it's your secret weapon for a peaceful, fly-free summer.
