Those of us old enough to remember . . .
. . . will recall the astounding results achieved by the Chinese when they decided to 'deal' with the problem of birds eating crops.
The European Commission (EC) has found €1,777,985 for research on rat-repelling laser fences. The thinking behind the “LIFE Laser Fence” is that birds and rodents chew on plenty of crops, which costs farmers money and reduce productivity. Plenty of farmers fight back using poisons which do the job, but can also prove fatal for …
And it's worth remembering.
And those of us smart enough to spot the subtle difference in approach between deterrent and elimination will understand why learning a lesson from an entirely different situation is not actually helpful.
The lasers scare the pests away. They do not kill them.
Going to have to be a very clever laser that distinguishes rats and pests from protected species that it is illegal to interfere with. In fact that reason will likely make this illegal to use in the UK. Shine this at a natterjack toad or a barn owl and cause them to do something that injures them and you'll be heading for a fine or even prison sentence..
Either they're testing this near my office, or they should be. A pigeon flew down the chimney next to my desk this morning, and perched on the back of one of our swivel chairs.
The windows don't open very wide, so I was expecting a bit of a struggle to get the bugger out - and a laser would have come in useful for that too. Managed it with the minimum of flapping and shitting - either from pigeon or me.
Seems like a better solution than random slaughter of wildlife though.
The best method is get a cat.
Adopt a neighbour's cat and encourage it to treat your garden as its home territory - a strategically placed planter of catnip and the giving of treats works wonders and the really good thing with this approach is that you don't have to worry about actually looking after a cat...
Otherwise get a Jack Russell, no cats, mice, rats...
I'd advise against giving it too much food, you don't want it getting overly attached, just interested and to know that's a friendly place, then it'll poop elsewhere making your garden part of the heart of it's territory rather than at the edge.
The key is being nice to it when you see it (or just ignoring it entirely) and putting out small treats every few days, but not daily.
My granny use to do this all the time, kept the cats out of her flower beds and in her neighbours lol
"We currently have the other issue that our neighbours "Ninja cat" sneaking in and nicking our cat's food"
"You can get cat flaps with RFID readers that read the chip in your cat, and only lets the right one(s) in."
My Sister has one and worked well for a while, then the neighbours cat worked out he could get in by tailgating (literally) my sisters cat.... they are damn crafty.
"The best method is get a cat. They don't tend to crap in their own garden, and they are territorial, so generally keep other cats away..."
Not. PBS (here on the left side of the pond) aired a show of a cat population in a small Brit town. "50 felines from the Surrey village of Shamley Green were fitted with GPS collars and 'cat cams'". In viewing the episode, it was discovered that while cats do avoid each other, they end up "sharing" an area by taking shifts. In fact, they discovered that (for the people who had cat doors), other cats come into their homes while the owners are not there and eat the food and share the house!
Thus, getting a cat will not eliminate or keep other cats away, it will simply cause your property to be time shared.

What about if you get a lion?
I admit you may be introducing an even worse poo problem. Although I believe you can sell it to other people to put in their gardens to keep cats away. There's also the problem of food, they're not cheap to feed, and if you're really unlucky, you may be on the menu yourself.
What is "humanus humanus"? Do you mean Pediculus humanus, or perhaps Homo sapiens sapiens?

And even birds get used to it after a while.
I visited a cow barn in the Netherlands where they had this system to deter birds. This system moved the beams around the barn. All that happened is that the birds flew from one part of the barn where the laser was pointing to the other part, and kept feeding, whereas initially it would scare them away.
>Birds apparently “perceive the approaching laser beam as a physical danger” and therefore go away instead of stopping to munch on crops.
So they starve to death? Is that the outcome we really want?
We aren't actually short of food, so this is just about profits. Perhaps we should rethink our ecological policy.
Please go re-read the article, slowly and with someone to help with the big words.
It's about stopping or cutting back on the use of poison which causes collateral damage through unintended victims and ultimately finds its way back into the human foodchain through a lengthy but documented process.
OK, it won't happen in the same way, and maybe not so easily. But academic cooperation takes place all round the world; people who want solutions to a problem can deal with any university that's best placed to supply them. It makes no sense to suggest that the criteria for this sort of collaboration are exclusively political or ideological.
Enough of the hand-wringing already.
and maybe not so easily
It's the entire string of maybe-not-so-easily's applied across so many areas like the economy, trade, research, policing, security and travel which is exactly what is worrying so many people. It looks like the government has decided that immigration is the prime concern and everything else should be sacrificed -- if necessary -- upon that altar.
If curbing immigration would solve enough problems to compensate, maybe then it would be worth it, but I don't see that getting to the root causes of our problems with housing, healthcare, education and the deficit. All that's going to happen is that there will be less money available and these problems will simply get worse. But you don't want to hear any of that hand-wringing, do you?
Good news!
Invention is a public good - it matters not one jot whether the mad scientists laughing as they burn through rat retinas are British, French or Korean.
Farmer Giles still gets the benefit simply by buying the resulting products.
So, out of the great pantheon of things that may (or mayn't) be affected by something they we will (or won't) do, leading (or not) to some decisions that no-one can predict, let alone map the consequences off, this is not one of them.
