There is an open drain with dirty stagnant water near my house in a gated village. The committee say they are not able to resolve the problem. I have read today that water like this during the approaching rainy season encourages the breeding of mosquitoes and greatly increases the risk of dengue fever. 

Can anyone recommend an approach to resolve this problem with for example regular spraying.

I would appreciate if the comedians on the forum directed their humour to other topics as I have existing medical problems and trying to avert further issues is a serious matter to me.

Spraying with insecticide will help but the spray will quickly be washed away when it rains

 

Better approach is just use insect repellent when you go out...or if possible avoid walking near it. The mosquito doesn:t fly very far from its breeding site.

The local government do some spraying around these parts at certain times of the year.

 

They occasionally spray something from a pickup in the middle of the night, I've seen it go past the house a couple of times, it's a noisy thing.

 

I believe they do this in areas where there are problems.

 

if I were you I'd spray it myself and when it rains just spray again, not sure how easy it is to get your hands on the proper insecticide for that particular type of mosquito though but I'm sure it's available somewhere.

 

 

They are not able to resolve it? More like they can't be bothered to. My legs, especially the ankles are covered in mozzy spray, every time I leave the house. And the room is sprayed each time we leave. Stay away from any open drains.

Put tiger balm on your skin.

Thanks for the advice. Is there an insect repellent you would recommend. Also any electric powered small machine that is effective.

In the first place, aedes mosquitoes choose clear clean water to breed so there is nothing to worry about.

Screens on doors and windows are a must in Thailand.Ponds, dams ,man made canals are everywhere mostly for irrigation it’s impossible to eradicate every suspect waterway.Fish eat larvae introduce some Tilapia a very hardy Thai fish that you can also eat when fully developed so 2 purposes taken care of.Sorry that’s all I can suggest we do that in our lake and it works not many mozzies.

 

We used something called '15', available everywhere.

It comes as a lotion and as tissues.

I'm not sure if it's good for the skin, but it works.

 

Additional, as already suggested, avoid any place

containing water, flower pots etc.

You might too search here on Thaivisa: 'dengue'

A lot of information. May be too much.

May be some friendly asking could help?   -   Committee? - Village head?!

In our village it took me and 5 other people last August, after suffering from dengue,

to start a spraying session. They repeated that later twice.

It's a very bad smell, sure not healthy but it seems to kill the mozzies.

Better close every door/window!  -  Better close every door/window!  -  Better close every door/window!

After spraying no more dengue cases in our village, in our Amphoe.

This everyone should understand.

Good luck!

 

Sorry, I forgot something:

 

For every woman, child or man Dengue might be a very bad thing!

Do you know what was used for the spraying sessions

Sorry, no.

But I'm sure, it's something not available at BigC or Tesco-Lotus.

Noticed this perfume before at other places too, Hua Hin, ChiangMai, ...

Take care!

Actually the dirty water ability to live is why they as such a problem in populated areas (unlike Malaria).

The highest average number of larvae can live in bathroom waste water with 160 gr soil which is an average of 18 on larval stage, 18 pupal stage and 18 adult stage. From the analysis given, it can be concluded that the A.aegypti mosquitoes can breed well in polluted water in direct contact with the ground.

Dengue fever is maybe a bigger problem than Covid in asia.

 

But nobody wants to make statistic on it, why is it not so interesting ?

 

Actually there is solutions to fight dengue, but it is only done in low scale why ?

 

Thailand tourist authorities should have more interest in this problem, if dengue fever will shows big numbers the western tourist will be scared away again.

 

Now the rainseason is comming the dengue threat will grow to a much higher level.

 

I know a village where they do spray something, I dont know what it is or where to buy it. I have a farrang friend living there, the village is spraying good except close to the farrang house. In my village we are all equal, here they do nothing to fight dengue. I got the idea that the dengue fight is giving out to the village level, that could be an explanation to the low level of dengue fight.

 

To me it seems like farrangs also in this way had to take of them selves.

 

I would like to know about this spray chemical, where to get it, then I will spray around mine and my farrang friends houses.

The chemicals used for outdoor spraying are harmful if inhaled or much contact with skin, need special equipment to safely use it.

 

Don:t try to dabble with that

 

Just apply insect repellant when you go out

 

7-11 sells several brands, they all seem to work. I would probably start with one of the natural citronella ones, if that doesn't work then switch to the chemicals

It's a job for the authorities spraying the whole village.

Suppose, it's not useful to spray only one's garden, while

the mozzies fly in from neighbouring areas.

Is it worth pouring bleach on to the metal grating above the stagnant water

I don:t think so

I like to use a bit of common with these mozzies.

 

Firstly; take away their holding areas. Secondly; make their environment uncomfortable. Thirdly; know what to do if you think you are infected.

 

Search areas that are out of the wind and quiet. Spray the area.

 

Go to a neem tree, get leaves, and use the leaves to deter the mozzies.

 

@Frotting (TVF member) did some great posts on Dengue fever some time back. Well worth a look, if infected. Natural cure.

 

And lastly; build up your immune system; just in case.

You can try pouring a little bit of cooking oil onto the water in the drain which will settle into a very thin film on the surface and stop larvae from breeding. Not an ideal solution but better than nothing.

Havnt read the article just saw the headline I suggest get a couple of live fish and throw them in the water they will eat the mozzies

A small amount of kerosene sprayed on the surface will help. 

I think I read the "average" person can sleep 33 years with no mosquito net in Northern Thailand and not get dengue.

 

But you are probably not in Northern Thailand and you're probably not average. ????

Like one of the member mention,  if possible put in some tough fish ( that can live in sever conditions) cat fish,  talipia etc, maybe if the fish survive then that will definitely helps. Best of luck.

I understand that mossies don't like oily substances. I don't know if your stagnant water is 'still' water, or if the water flowing - (as in a stream).

If the water is still, try adding a cup of soapy liquid to the water and maybe stir it a little.

Depends on the amount of water you have, too.

You could try bleach as an alternative?

The mossies like still water. If the water is flowing, you won't get them laying their eggs - so you would be safe as far as that water is concerned.

I was thinking of a litre of motor oil, the larvae can't breathe through the film. Environmental vandalism I know, but it is a question of the OP's priorities.

Tilapia is native to Africa and the Middle east but is now farmed pretty much world wide.  Also they eat plants so I don't think they would help with mosquitos.

take vitamen b+ pills and they wont bite you and poor some sump oil in the water and mossys cant breed in it

 

The Aa Ba Ta where I live will give you free packets of mosquito larvae killer if you go ask. 

Quote:-

A thin coating of oil on top of water suffocates mosquito larvae, killing them quickly. Use natural oils, such as olive oil or vegetable oil, for this control method. You also can use cinnamon oil. You only need 1 teaspoon of oil per gallon of water.

 

This method reduces the surface tension of the water and the larvae cannot get air through their breathing tubes.
