What is safe to put in water troughs to kill Mosquito larvae and algae??
Our lambs refuse to drink out of the troughs (I don't blame them) and the cows are not impressed.
Any advise appreciated thank you

Can you take all the current water out and put new water in? Putting more stuff into unpalatable water probably isn't going to solve the problem.

Hi, the best thing for mosquitoes in water troughs is put a few drops of cooking oil in the trough, it shouldn't affect the cattle at all, what it does prevent the mosquitoes coming up to breath. We have used it on fish ponds so it is safe, and works well. Good luck.

Cheers

We have already changed the water and scrubbed the trough twice and they just come back :(

We will try that, thanks :-)

I doubt very much that it is the mosquito making the water unpalatable, more likely they dont like the flavour of the water as I have never seen stock put off by algae or mosquito when they are thirsty.
Goldfish eat the larva if that is a big issue for you
A small amount of copper sulphate in troughs - 1/2 to 1 tspn will stop the algae

An egg cup of kerosene will do the job. The film on the water prevents the wrigglers from breathing air.
When cattle and sheep drink they break through the oily barrier and suck water from below the surface so they don't ingest the minute amount of oil.

there are better types of trough available now. The old concrete ones attract mossies and algae. Have a look on Trade Me.......

5 acres, Ferguson 35X and implements, Hanmay pto shredder, BMW Z3, Countax ride on mower, chooks, Dorper and Wiltshire sheep. Bosky wood burning central heating stove and radiators. Retro caravan. Growing our own food and preserving it. Small vineyard, crap wine. :)

We got some trough block from farmlands and it has kept the water free of bugs and algae

Will that work for the tanks we use for drinking water? Might be better for us than mozzie larvae - but doesn't it go rancid?

Hi, the cooking oil would be safe to use in tank water which you would drink. There maybe a slight oily film on a glass of water. I would check that there exits and entrances to your water tank are reasonably sealed to stop the mozzies entering. You could use some Janola in the tank that would kill the mozzies which could help instantly to clear the water. Somebody on here will have the quantity for Janola, you would have to let us know the size of tank, and then we could give you the dilution for the Janola. It is quite safe to drink and it clears the water of the bugs. Cheers.

Cows and sheep dont care that there is mosquito larvae in there - you do. Its most likely something else causing them not to drink. Duck shit in the bottom is a common cause, blue green algae is another one. You could go to Farmlands and get a sample of caramel flavouring and see if that makes a difference. If they are thirsty they will drink from it.

The tanks are about 5000 gallons, about 22.500 litres I think.

All plastic water tanks need to have a vent in the top otherwise they collapse when you stuck the water out. Cooking oil works in a tank as it floats on the surface, you draw water from the bottom

We got it sorted with trough block and a fantastic idea I had of circulating the water, which also keeps it cooler.
