Silverfish in the Home: How a British Engineer Solved the Problem — Without a Single Chemical
It always starts the same way. You flick on the bathroom light at 2am, and something long, silver and fast darts across the tiles and disappears behind the skirting board. If you've ever felt that little shudder, you already know what a silverfish is — and you know they never seem to come alone.
For thousands of UK households it's a quiet, embarrassing battle that drags on for years. And according to a growing number of experts, almost everything people are told to do about it is wrong.
People assume silverfish are a sign of a dirty home. They're not. It's a structural problem — moisture, warmth and tiny hiding places. You can scrub a house spotless and still have them. — Dr. Sarah Whitfield, entomologist, University of Leeds
Why the usual methods fail — and quietly drain your wallet
Karen Willis, a 42-year-old from Nottingham, reckons she spent more than £400 over two years trying to get rid of them. "Traps, sprays, gels, little plug-in gadgets, essential oils — you name it, I bought it," she says. "It worked for a week, then they were back like nothing happened."
Her experience lines up with what specialists have been saying for a while. Most shop-bought solutions treat the symptom, not the source. Sticky traps catch the handful of insects out in the open while two hundred more breed behind the walls. Chemical sprays are unpleasant around children and pets, and silverfish quickly build a resistance to them. And the home remedies — lavender, lemon peel, cloves — might smell lovely, but they don't touch a real infestation.
Most of what's sold for silverfish is, frankly, a waste of money. It gives people the feeling of doing something while the actual colony is left untouched. — Dr. Sarah Whitfield, University of Leeds
The Sheffield engineer who got fed up and built his own solution
David Hart never set out to launch a product. A retired electrical engineer from Sheffield, he simply got tired of watching his wife refuse to go into their own bathroom at night.
"I'm an engineer. If something's broken, I want to understand why," he says. So he did what engineers do — he went to the research. What caught his attention was a body of work on how certain high-frequency ultrasonic pulses interfere with the way small insects sense and navigate their surroundings.
Working at his own bench, David built a compact plug-in unit that emits a continuous, precisely-tuned ultrasonic signal — completely inaudible to people and pets, but deeply disruptive to silverfish and other crawling insects. He tested it in his own home first. The result, in his words: "After about three weeks, we simply stopped seeing them." No spraying, no dead insects to clean up — just a quiet device left plugged into the wall, working around the clock.
That device became BugShield, and you can see the technology and current availability on the official Domivelo store here.
How the ultrasonic technology actually works
BugShield emits patented ultrasonic sine-wave pulses in the 30–50 kHz range. Humans can't hear it and it's harmless to mammals, but for silverfish it scrambles the signals they rely on to orient themselves and feed. The treated area quickly becomes somewhere they instinctively avoid, so existing populations move out and die off.
Because it works on their senses rather than with poison, insects can't build a resistance to it the way they do with sprays. It draws about as little power as a small LED night-light, needs no refills or maintenance, and is completely safe to leave running around children and pets. You plug it in, and you leave it.

Why is BugShield so often sold out?
Because each unit is made and quality-checked in small batches here in Britain rather than mass-produced overseas, stock is limited. BugShield has already sold out several times this year, with some customers waiting weeks for the next run. It's in stock right now — but during the last 50% promotion the full allocation was gone within hours, and once this batch sells out the price returns to the regular £99.98.
The bottom line
You've two choices. You can keep sharing your home with silverfish and keep spending on sprays and traps that don't hold — or you can plug in a small, silent device that's already worked for more than 15,000 UK households, with 94% reporting they were free of silverfish within about three weeks. With a 90-day money-back guarantee, the only thing you're really risking is finally being rid of them.
