Two Hour Coypu Fence Assault

Yesterday I made a temporoary repair to a new hole in the fence. Which you can see in the footage below.

The coypu twins arrived at 3:30 AM and were at the fence until 5:45 AM. I have forty 15 second clips of them chewing and digging.

Look at the size of the teeth on this little bugger.



The three strand electric fence has been disturbed and the witness sticks away from the fence near this corner have been moved.

My guess is they gave up on the wire fence and risked the electrice fence as dawn approached. Having been shocked they went in the pond away from the electricity.

I’ll probably put a fourth strand in the electric fence this afternoon.

The local farm store sells a battery operated electrificator which has 2.8 Joule pulses at ten thousand volts. That is more than a factor of ten higher…

Might be worth a hundred euros…

I have ordered some more fencing to repair where there are other holes.

The Coypu Saga Continued…

I extended a single strand electric fence over the most recently chewed hole and plugged in the HV.

I went out to inspect this morning…





The wire had been moved upwards and the support posts twisted consistent with an ingress attempt. The witness sticks around the pond had been moved so I assumed success.


Around 9pm CET time there is a movement to the left consistent with a shocked Coypu running off.


Around 4AM the camera is triggered but no Coypu recorded. You can see the wire twisted up. The blighter came back. It is probably hungry as the river is in flood so no access to bank and river bed food.


Just before dawn getting a hurry up shock on the way out.


It looks as though he is learning to take the risk for the reward.

I guess a shock to the nose is worse than to the back.

I will put two strands across the hole later today.

Coypu Chewing Fence – Caught in the Act!

Herewith the evidence for the prosecution M’Lord…


Big Daddy Coypu chewing the fence and making ingress yesterday evening…


This looks to be sound evidence. He was back again just before 4AM. I think he “plops” into the river, floats downstream and then returns to his rounds. He has made several holes. To the right you can see small logs blocking his previous forays.

Time for boiling oil from the parapets or greased lightning.

….It’s electrifying…

Coypu – Nutria – A Global Problem?

Based on last night’s trail cam the little blighters did not come up off the full river, nor did they cross the bridge. It is pissing down today. I walked around the pond and at the edge of the property I noticed what appears to be a freshly chewed hole in the wire mesh fence. The mesh wire is more than a couple of millimetres thick. That is some chewing.

I’ll monitor the hole tonight and if they come through, I will extend a single strand of the electric fence to cover the hole. I might run it wilderness side to protect the fence.

From the internet these coypu are a problem in Europe, Japan and USA.

I have read some interesting ideas some of which might not be accurate. The Americans prefer guns. Though on one forum I saw juicy fruit chewing gum mentioned.  Juicy fruit has a strong odour. The protagonist suggests that the Coypu cannot pass this so they die of constipation. Another suggestion was chocolate Ex-lax laxative. Apparently, this causes them to shit themselves to death.

When I was a kid, as a prank, I offered one of my school friends some Ex-lax. I even told him it was laxative chocolate. He ate it, nevertheless. Half an hour later he had to leave class in something of a rush. People sometimes do not believe the truth.

Clearly, coypu are something of a hobby / irritation for many around the globe.

They were introduced into Japan during the second world war to provide fur…

You learn something new every day…

We have some lemon flavoured Movicol in the drugs store and I can probably source some industrial grade Pico-lax before my next colonoscopy…we have loperamide and racecadotril or acetorphan, too.

Hmn….
