Somerset Farmer Shares the Simple Fix That Finally Stopped Mice Destroying His Chicken Coop and Tractor Cab

"I was finding droppings in the feed bins every single morning. Went through traps, poison, the lot. Then my daughter told me about these pouches and I thought she was having me on."

Dave Pearson has been farming for over thirty years. He runs about 140 acres of mixed arable land and keeps roughly 200 free-range laying hens on his holding just outside Yeovil in Somerset. For the last few years, though, mice have been making his life a misery.

"It started getting properly bad about three winters back," Dave told me when I visited his farm last month. "You'd open the coop first thing in the morning and there'd be droppings everywhere. In the nest boxes, all through the feeders, on the floor. The hens were unsettled. Egg numbers dropped right off. I was chucking away feed every other day because it had been got at."

But the chicken coop was only half the headache. Mice had also set up camp in his tractor cab, his grain store, and the barn where he parks the quad bike and keeps his tools over winter.

"You'd sit down in the cab and there's shredded insulation everywhere. They'd properly gone to town on the wiring loom under the dash. My mechanic said he sees it all the time, farm vehicles sitting idle over winter. Cost me close to eight hundred quid to sort that out."

Why Mice on Farms Are Getting Worse

Dave is far from alone with this. According to the British Pest Control Association, rodent call-outs for agricultural properties went up by more than 20% between 2022 and 2024. Milder winters mean mice are breeding for longer, and modern farming equipment, with all its electronics and insulated cabling, gives them plenty of material to chew through.

Where Mice Typically Nest on UK Farms

"I tried everything going," Dave says. "Snap traps everywhere, those ultrasonic plug-in things from the internet, even had the pest bloke out twice. The traps catch a few but there's always more where they came from. And poison - well, you can't be putting poison down where you've got chickens roaming about, can you? I actually lost a hen and the vet reckoned she'd eaten a poisoned mouse. That was it for me with poison."

Chewed wiring inside a tractor cab. Repairs like this can cost farmers hundreds of pounds each year.

The National Farmers' Union estimates that rodent damage costs UK agriculture around £20 million a year, much of it from contaminated animal feed and damaged machinery wiring. But for individual farmers like Dave, it's the daily frustration that really wears you down.

How Dave Found a Different Approach

It was Dave's daughter Lauren who spotted something online last autumn. "She rang me up and said, 'Dad, have you seen these repellent pouches? They're made from essential oils, you just leave them where the mice are getting in.' I thought she was having a laugh, honestly. Peppermint oil keeping mice out? Sounded like something off one of those daytime telly adverts."

But Dave was fed up enough to try anything. He ordered a pack of PRACTS HOMECARE Rodent Repellent Pouches and scattered them around the worst spots on the farm: two in the chicken coop, one in the tractor cab, two near the feed bins, and one in the barn.

"I'm not exaggerating when I say within about four days, the droppings had stopped in the coop. I kept checking because I thought it might be a fluke. After a fortnight, there was nothing. Not a single dropping anywhere. The hens settled back down and we were getting proper egg numbers again within about three weeks."

How the Pouches Actually Work

I asked Dave to walk me through what he did, because it really is straightforward.

1
Take a pouch out of the pack Each one contains a concentrated blend of peppermint, cinnamon, castor oil and cedarwood. These are scents that mice absolutely hate, but they're harmless to poultry, dogs, cats and other farm animals.
2
Place them wherever mice are a problem In the coop near nest boxes, inside the tractor cab, by the feed store, in the barn. Anywhere you've seen droppings or damage. No wires, no plugging in, no batteries.
3
Mice clear off within days The essential oils create a scent barrier that mice simply won't cross. They move on and find somewhere else. Each pouch stays effective for up to 90 days, so one set covers you for a full season.

The key selling point for farmers is the safety angle. No poison means no risk to your hens, no secondary poisoning risk to barn cats or working dogs, and no worry about contaminated eggs or meat. And unlike traps, you don't have to check them, empty them, or reset them every day. You just pop the pouches in place and crack on.

The Difference on Dave's Farm

BEFORE: Droppings daily, contaminated feed, stressed hens, fewer eggs
AFTER: No droppings, clean feed, settled hens, egg numbers back to normal

"The tractor's been clear as well," Dave says, showing me the cab. "Popped one on the dash and one under the seat back in October. It's June now and not a bit of damage. My neighbour Keith, dairy farmer up the road, he came over and saw the state of the coop compared to what it was like. Ordered himself three packs straight away."

"Honestly, the amount of money I've wasted on traps and pest control visits over the years, and these little pouches for a fraction of the cost have done a better job than any of it. I feel a bit daft for not finding them sooner."

I've got about 40 hens and a handful of ducks. Mice were getting into the feed bins, the coop, even the duck house. Couldn't put poison down because of the birds. Stuck these pouches in about three weeks ago and there's been a massive difference. No droppings at all in the nest boxes now. Really chuffed.

Mice chewed through the loom in the combine last autumn. Cost a fortune and nearly put us behind on harvest. Put these in all the cabs and the grain dryer shed over winter. Come spring, not a bit of damage anywhere. Proper job. Well worth it when you think what the mechanic charges.

Was properly sceptical because I've wasted money on all sorts over the years. But these actually work. Took about five days to see a difference in the hen house. My husband stuck a couple in his workshop too and says it's cleared up in there. Only four stars because I wish they were a touch cheaper, but they do the job so I can't moan really.

On my third pack now. Use them in the hen houses, cattle shed, and all the machinery over winter. Saves me a fortune in pest control. The smell's actually quite pleasant, sort of minty. Chickens don't mind it a bit. Dead handy wee things, wouldn't be without them now.

Common Questions From Farmers

Are these definitely safe around chickens and poultry? +
Yes, completely safe. The pouches contain only natural essential oils: peppermint, cinnamon, castor oil and cedarwood. They're non-toxic and won't cause any harm to poultry, other livestock, farm cats or working dogs. That's the main reason farmers prefer them over poison-based solutions.
How many do I need for a chicken coop? +
For a standard coop housing up to about 20 hens, two or three pouches should do the trick. Put one near the nest boxes, one close to the feeder, and one by the doorway or any gaps where mice might get in. For bigger walk-in poultry houses, you might want four to six. Each pack has 12 pouches, so one pack usually covers the coop plus a couple of other trouble spots.
Do they work in tractor cabs and farm machinery? +
Absolutely. A lot of farmers buy these specifically for protecting machinery over winter. Just tuck one on the dashboard or under the seat of any vehicle that's going to sit idle for a while. They work really well in combine cabs, telehandlers, quad bikes, and any enclosed space where mice like to nest.
How long does each pouch last? +
Each pouch stays effective for up to 90 days. Most farmers swap them out once a quarter. In very draughty or exposed spots they might need replacing slightly sooner, around 60 days or so, but for enclosed spaces like cabs and coops they last the full three months.
What if they don't work for me? +
PRACTS HOMECARE offers a full 60-day money-back guarantee, no quibble. If you're not seeing results, just return them for a complete refund. Based on what we've heard from agricultural users though, the vast majority notice a real difference within the first week or so.
Will they work on rats as well, or just mice? +
The pouches are designed to repel all common rodents, including rats and mice. Several farmers we spoke to reported good results with both, though rats can be more persistent so you may need a few extra pouches in problem areas.

No poison. No traps. No fuss. Just place the pouches and get on with your day.

Ordered some after reading this. Put them in my grain store and the chicken run on Tuesday. By Friday the droppings had pretty much stopped. Absolutely brilliant. The wife's happy because the coop doesn't stink of mothballs anymore either, these smell quite nice actually. Minty.

We've spent hundreds on the pest control man over the years and tried everything. These little pouches have done more than all of it put together. I keep bantams and the mice were actually eating the eggs. Not any more! Honestly can't say enough good things about them.

Cheers for this article. I'm a contract farmer in Lincs and mice have been a right pain in the combine and the seed drill. Put pouches in both over winter and everything's been clear this spring. Already told half the farmers round here about them. Saving me a packet in mechanic bills.

Anyone know if they work on rats as well or is it just mice? We've got a bit of both near the feed store. Ordered some anyway but would be good to know.

Emma, I haven't had rats myself but it says on the pack it works on all rodents. Definitely worth a go. The mice have completely gone from mine, so I'd think it'd at least help with rats too.

On my third pack now. Run a smallish poultry setup in Norfolk, about 300 layers. These are just part of my routine at this point. Swap them out every three months and haven't had a mouse problem since last September. Best money I've spent on pest control, full stop. Those ultrasonic gadgets did absolutely nothing by comparison.
