mosquitos in our tank, how to kill

[stupidfarang]

Hi, we have mosquito's by the thousands in a sewage tank, what can we use to kill them?

[cooked]

Spray with a normal insecticide, if possible empty the tank? Then scatter a small amount of Proline 1% SG or similar to prevent larvae from developing. Repeat. You can get Proline at the local clinic or in pharmacies.

Thank you for the info, have just moved into the house a month ago, the owner came yesterday an placed oil in the tank then another liquid "PANDA" brand not sure what it is, anyway it has worked. I will try the Proline 1% SG next month or when ever the mosquito's return.

Very thin layer of oil on the surface works by blocking the breathing tube on the larvae.

 

Anything that breathes through it's bum can't be good.

They won't come back if there is oil in the tank. The larvae can't breathe with a layer of oil obstructing their access to air.

Never heard of  mosquitos in a sewage [septic] tank.

You would think it would be too toxic for anything but bacteria to live in.

In any other kind of a tank the introduction of small fish usually solve the problem.  They eat the luk nahm as fast as they appear.

We have little fish in our lotus ponds and no problems with mosquitos.

Fish  can not  survive in a toilet tank. They  require dissolved oxygen.

Please try the oil-only solutions recommended in this thread ... any chemicals you add will likely leach into your environment and make life difficult for frogs ...

Harmless to aquatic life.

It's obvious it's a fresh water tank. Mozzies can't live in sh-t.

Still use only oil, fewer chemicals the better.

Can be worse when they speak out of it.

[stupidfarang]

thank you everyone for the info, appreciated

The local ah ba ta gives out these little packets of granules to put in ponds etc. for free.  

[HighPriority]

Seal the tank openings.

If you want to kill all just drop some bleach (clorox). It will kill everything very fast.

[anterian]

they use surface tension to cling to the surface and breath adding washing up liquid lowers the surface tension such that they cannot cling, so sink and drown.

Interesting. 

[Snow Leopard]

I know what does work for sure. It would depend on the environmental situation you have and the size of tank involved. A few drops of diesel will kill the lot instantly.

Yes a couple of drops of baby oil will do the trick

In Oz a small amount of kerosene is even put into rain water tanks, i was told it prevents mozys laying their eggs.

[Iron Tongue]

Yes, as a kid, I always saw people using kerosene to keep mosquitoes away from open water.

 

Bleach works, but it evaporates really quickly so you'll need to check it daily.

maybe OP meant to write; Sullage Tank? 

i.e. for grey water 

 

 

maybe throw some fish in... not necessarily goldfish, being to dainty. Then keep replacing the dead fish each morning... they crave mozzie  wrigglers

I think that breathing method might apply to Australian politicians ... they certainly seem to talk through their bums lol ????

Not limited to only Aussie Pols sir!

Kerosene was the go in drinking waterfront tanks or septics not the people.

Yes they can, we have a barrel with a bag of buffalo sh*t dissolved in it,for fertilizer

and it's full of mosquito larva, also reading a story where this farmer in

Thailand grows Mosquito larvae under his chicken pens,full of water and

chicken poo,and sells the mosquito larvae to freeze dryers who sell for fish food.

Oil is the best and safest way to get rid of them.

I suppose my meaning was on the under ground tanks that hold everything from the toilet etc, the soakaway types that don't go to the sewage system, but I take your point.

[Foexie]

Hi,

 

what kind of tank do you use? Is it one what have to be emptied or is it one with 2 compartments what is used as a water cleaning system?

 

Because the second one uses bacteria. And i think it is not a good idea to use chloride or any other chemical product to kill them ( even an oily seal). Because this could also kill your tank bacteria.

 

I have one like that also but i have a constant airpump working what make the water bubbling. This airinfusion also helps to make the water cleaning more easy for the little friends.

 

And mosquietoes only lay eggs in standing water. So i think this is the easiest and healthiest way to get rid of them.

[zyxwv]

a little kerosene is what I put in my water tank. The kerosene stays on the top (kills mosquitoes) and the fresh water (water tank) is still fresh when comes out of tap at bottom.

Yes. They must be getting in somewhere which shouldn't be happening. For health reasons it should be a sealed environment.
