If your pond is not stagnant, you shouldn't have mosquitos. If there is a current in the water, I believe mosquito's won't survive. Besides, the fish would eat any larvae in the pond. What you likely have is midge.... they're a small insect, always swarming around the pond, sometimes in large numbers. They're harmless and won't bite you, and their larvae is the bloodworms commonly found in the filter chambers. These also make good food for the fish.

Re: [timmychan] mosquitoes - how to rid them?? [In reply to] Can't Post

use UV light .. very effective .. u can see a layar of mosquitoes on the surface of your filter. I personally did not cover the filter so can attract mosquitoes to go and lay egg .. then the UV light will just kill them. Help to reduce the mosquitoes arond your house area as well. I still remember the builder of the ponds complaint about mosquitoes problem when they dig the ponds .. its like if you stay out for 5 minutes you will sure get bite from them. With the UV on ... this problem gone ... a lot less mosquitoes now .

I think I killed more than 5,000+ mosquitoes, or more ?

cwloo,

When you say you leave your lid off the filter, isn't it then exposed to direct sun light ?. If this is the case how do you keep your water params down ?.

Hi Cwloo...I thought UV light is harmful to human body?!! I heard from someone once put in this forum that UV light can also cause blindness if someone stare at the light even for a short moment. How do you keep you UV light to kill the mosquitoes and their eggs? Do you meant you keep the UV light on without cover? Isn't that a bit dangerious if someone (ie a child) go to touch it or look at it? Please explain. Thanks.

Re: [DANNY] mosquitoes - how to rid them?? [In reply to] Can't Post

no , the UV light is cover, it's only the filter is not cover.. I put the UV light inside a box which face down to the filter. Thus the blue light will attract mosquitoes to come at night and get kills later.

The UV won't cause blindness if u only look at it for a short moment, by short I mean less than few seconds. If you scare that the kids go around the UV light you can put a timmer on it and only swtich it on at night.

This could mean that your UV light is near the end of lifespan. Remember if you switch on the UV for 24hrs a day it lifespan is only 6 months. Try to change the UV bulb and check the effect, dont forget to ask for UV light that kill gems .. as some of the shop sell the wrong one to you.

Re: [cwloo] mosquitoes - how to rid them?? [In reply to] Can't Post

Hi all!

My opinion, i don't like to use UV, cause it's harmful to every living thing! and we have to use it very very carefully. For my choice, i won't use a UV unless there are no more chances left. I do have a UV light too, last time i use it for 24/7! everyday! although is not a really big unit(not sure the size) but it really cost alot buying that unit and for the electricity bill! and UV causes alot of problems too! like always getting brown color substance! i think it might be the "dead body" of the algea!

Thinking of Mosquitoes surviving, in the filter chambers, in the pond...is this possible? I don't think its possible is the pond is alwasy moving, water in the filter chamber is always flowing. and are they really mosquito larvers? or are they those red worms?

Regards,
John

John,

If you DIY your own UV light it is not that expensive.. Just buy the light bulb, normal light transformer or those fluorescent light bulb kits and you are ready to go.

Yes, it's really larvers inside the filters as you can see them "swim" around the surface of the filters. I'll get some shots when I got myself a digital camera.

I found in my high mosquito area...that to get rid of larva, don't have as many adults. My answer was bats. Bats eat thousands of them a night. So Has anyone tryed putting up bat boxes on their properties? Any little bit helps and I don't get bit by the adults near as much as I used to!

Aren't Bat droppings toxic to koi ?

here in the UK, I have never seen a bat. So I guess it would be used by birds instead which is no good.

In my opinion, not a good idea to have bats around the house let alone near the koi pond!

Bat bites could cause rabiesa as well as a host of other diseases. Crazy And yes, bat droppings would created a lot of mess and most likely toxic to kois!

Better not to introduce bats to the neighbourhood as it would cause a nuisance as well. There are other ways to get rid of mozzies. I have gardeb spiders to do the job and you can also plant mosquito repellent plants near your pond.

Re: [andyng] mosquitoes - how to rid them?? [In reply to] Can't Post

spiders are good but will not be able to totally get rid of the mosquitos.
just to re-cap:
1)My pond no mosquitoes or larvae
2)Mosquitoes and larvae in filter chambers
3)Lots of newly emerged mosquitoes in chambers - can't fly properly yet, wings not steady
4)Has UV light (20 watts) in filter chambers
5)Water flowing in pond and chambers
6)Have applied "abate" (mosquitoe larvae) insecticide into pond but can only last a week or so. After changing / topping up water for a week or so, the mosquitoes and larvae are back.
7)I believe "dimilin" will have the same effect as in "abate" in (6) above???
8)Have asked around aquirium, fish farm and hardware shop in Kuala Lumpur but can't find "dimilin". Anyone can recommend where to find??
8)Malaysia is a hot tropical country and plenty of mosquitoes. Any good long term suggestion to get rid of the mosquitoes and larvae??

Thanks and regards

I used Dimilin to good effect but it has to be in 2 to 3 week cycles in order to kill the emerging eggs as well. The treatment will also kill any anchor worms. Dimilin basically prevent the moulting cycle of crustaceans like invertibrates.

You can buy dimilin from Cheras Aquarium , Jln Ulu Pudu(further up from jusco maluri and landmark is the Gerakan HQ Building) at Rm 1.20 per gram. Dosinage is ~ 1 gram per 1000 gal.

Re: [timmychan] mosquitoes - how to rid them?? [In reply to] Can't Post

Why don't you guys prevent them to lay eggs and multiply in you ponds, I myself use the preventive strike, I use 10-20 "Leuciscus Idus" (I am dutch don't know how you call this in english) Those are school fish, pretty, fast, and when musquito-proof they love them and can live weeks with only the natural food supplie -> midge-egs/larves. Another advantage is when they are big enough that they are also heron-proof

Can't do that because they will only last about 2 seconds in my pond. Other than Koi, I have lots of Malaysian river fish like red kelah, tapah, temoleh, sebarau, arowana, kalui, jelawat, patin, etc. They are predatory fish and love small fishes.

I thought these are water mosquitos which do not bite. Most filter tanks have them which are being ignored as they are not harmful to human. Correct me if I am wrong.

In case yours are those harmful mosquitos, why don't try cover your filter tank with those fine aluminium net which only cost S$1.00 per ft run of 1 metre wide. I have tried that and is found to be effective but I didn't put it now as I think they are harmless water mosquitos .

Best regards

    I seem to have seen some aquarium shops selling snail killer in different brands. As I am not bordered by snail, I do not pay much attention. If the kois were to eat up all the eggs before the snails are hatched, then it shouldn't be a problem right?Sly

    Hello from NY!

    According to another Koi forum (Water Gardening Magazine's) a product sold here in the US, called a "mosquito dunk" (or mosquito donut) is the thing to use. It is inexpensive (one place charged 20 for $20) and harmless to frogs, fish and pets (one woman's puppies ate some before she put them in the pond. They had did not get sick at all and are now mosquito free.)

    It is a biological control, not a chemical control and in wide use here now that the West Nile Virus is spreading across the US.

    When put in ponds, they are supposed to be anchored so they will not float, but I would put them in the filter box then they Koi could not get to them.

    See if you can find them in stores that sell plants or home improvement items.

    Hi friend of NY, welcome to this forum !!Sly

    It sounds like something good for the pond owners who are annoyed by the mosquitos problem since it is harmless to kois and most animals. The price also seems reasonable provided the dossage is not that large for mega pond and frequency of replenishmet in not that high. It is definitely worth a trial if any one can find this product and post it in the forum on the brand name, price and where to get.

    By the way , can you provide the website of the Water Gardening Magazine for us to check on the particulars. Tks and regards.

    Hi, Koifun! Thankyou for the warm welcome.

    Here is the website for Water Gardens magazine:
    http://www.watergardens.com

    WARNING!!! They have a terrific forum subsite. The forum titles here are:
    Pond Chat - all kinds of pond chat & photos
    Party Line - socializing for ponders
    Pond & People Gallery - the name says it all
    Aquatic Plant Exchange - Plant sharing (one should be aware of your states/countries plant import restrictions so you don't accidentally get in trouble with the authorities if they track your shipment)

    Now you will be spending all your free time on the internet!
    Sly

    I've also researched the net for inexpensive mosquito dunks and find that they are not as cheap as I quoted. I've checked around (including Ebay) and find that mastersons.net will sell 20 for $US 29.99 ($1.50 each.)

    On online store, www.daydreamergardens.com, had the following information on the dunks:

    Bacillus thuringiensis (BT). One dunk provides protection for 100 square feet of water for up to 30 days. The agent, Bacillus thuringiensis (BT), comes in the form of a floating doughnut and slowly dissolves into surrounding water. While floating, they slowly release a natural mosquito-killing biocontrol agent at the waters surface. This agent gradually settles in the water where it is eaten by mosquito larvae growing there. Alternate wetting and drying will not reduce their effectiveness. Unused dunks will remain active indefinitely.

    To prevent dunks from being washed away, anchor them using a string tied through the center hole, or they can be staked in place. Each Dunk treats 100 sq. ft of water surface regardless of depth. Mosquito larvae will feed on them and will be killed continuously. They do not hurt fish, birds, or children. You can use them in birdbaths, shallow puddles of standing water and even in areas that are only sometimes covered in water. One can find both items in hardware stores and some companies do sell them via mail order.

    What about mosquito fish (Gambusia affinis)? Are they an option for you? I've found baby fish and tadpoles living in my filter box before. If you wish, I can post something about these little guys. It was copied and saved for my future use.

    I hope this helps. I, too have mosquitoes in my filter box and will go out and buy a package today. Take care!

    Hi Deb

    Thanks for your quick response.

    I have visited the website http://www.thewatergardenshop.com/1332.html which shows pictures of the donuts u mentioned. With this picture, it is definitely easier to scout around in the local shops. For me, this donut may be good for keeping mosquitos away from my water plants in my big water pot which is always filled to the brim with water. I currently use a type of mosquitos control chemicals to prevent larvas. It works but it is toxic to touch - becos of its toxicity and bad smell, I have to wash my hand now and then when accidentally touch the water.

    I will find out more from the other websites recommended by you when I have more time later.

    Have a nice week ends. Cool

    Your house is quite a distance from my place. I stay in Saladaeung, near Silom.

    I saw a lot of advertisement from Shipmate and always wanted to go there. How are the koi there? BTW, have you been to the place near Lapow the Saki dealer? I went there once and the fish are very nice but expensive. Some of the 40cm kohaku are selling at 20k baht.

    Will give you a call to chit chat later.

    understand that dimilin is about RM1.20 per gram from cheras aquarium. (work out to RM300 per packet of 250 gram)
    i found a farm dealer who is willing to supply at much cheaper price but will only sell in minimum one carton. one cartons contains 20 packets of 250 gram per packet.

    Anyone interested? i was thinking of buying one carton provided i can get at least 10 person to show interest first. you dont have to pay first but if about 10 person interested i can proceed to buy and sell to anyone interested. Price RM120 per packet of 250 gram. you collect from my office in KL golden triangle. i do make a nominal profit to cover for my time, effort and up-front money and risk can't sell the balance. then have to use the 5 kilo of dimilin as stock for next 10 years to kill off mosquitos.
    Anyone interested please e-mail your interest to me at timmychan@tm.net.my. no money needed to show interest but please be genuine so that i can proceed to purchase.
    would be good since dengue epedemic in KL / selangor now and reduce risk being fine by the authority for breeding mosquitoes.

    The chemical name for DIMILIN is DIFLUBENZURON. DIMILIN is a tradename belonging to Bayer> The local appointed agent is Halex (M) S/D. It comes in a powder form of 25% active and balance inert filler. I get it from the appointed agent at RM55 per bottle of 250 gm.

    I have tried for several years to get bats into my two bat houses, to no avail.. Not sure why.

    There are MANY myths regarding these creatures, and the risk of getting rabbies is grossly exaggerated. Probably more likely to get it from many other animals in the neighborhhod than from bats, which first of all, tend to be nocturnal so the opportunities for contact are much more limited. Check out www.BatCon.org for more info..

    Also, bats eat thousands of insects each nite, while Purple Martins (which have their own web site and need humans to provide homes for them) eat as many beneficial insects as mosquitoes, despite the common belief that they are great mosquitoe killers.

    As for bat dung, just keep your houses away from the pond. While water may help attract them, a good pond location may not be the best place for your bat houses.

    I wonder why do we have to use uv filterPirate and chemicalsMad to ge rid of mosquitoes.

    The easiers solution is to put some mosquito fish Smile(aka longkang fish in Malaysia) in to the filter and the pond. These little guppy like fish will survive in very adverse condition and will eat away all the mosquito larvae.

    It cost a ringgit for a bag full.Wink

    U see, many of the koi keepers keep very heavy aeration in their filter chambers to promote bacterial growth to 'super charge' thier filters for better performance. There's so much air pumped in (using large hi-blows) that the surface of the water in the filter chamber is so turbulent it's likened to putting your fish in a washing machine - they won't survive long being tossed around all day and night.

    There will however sometimes be dead spots in places in the filter where these mozzie larvae somehow or other manage to survive where no fish canCrazy.

    ..... hence the need to find other means of controlling pesky mosquitoes.

    That said however, my very large filter (which is not super aerated) is home to a myraid of fish to control mosquitoes. I have hundreds of nice fancy tail guppies (all from probably less than 10 fish), fancy goldfish and even discus! That said again, my filter is probably bigger than many people's pond!Laugh

    Gambusia (AKA Mosquito fish)
    They are $27/Box of 500.

    They are a HOOT for the kids. They are like tiny parania to anything that lands on the surface. I used to feed tubifect (sp?) worms. The Koi would eat chunk whole, but the Gambusia would make the water foam as they tried to tear pieces off the hunks.

    In bad winters, they don't make it, but at $27/box who cares...

    Ah.... the joys of being in Malaysia. Gambusia (aka mosquito fish, wild guppy and in malaysia also commonly known as 'longkang fish'- literally translates to ditch/drain fish).

    This fish, commonly sold as feeders cost more like RM5 for 500 of 'em! (Roughly translates to US$1.25). Plus, there are no winters in tropical Malaysia so U'd soon get about 1000 of 'em in the pond.

    Down side with these fish is disease. Many of 'em carry parasites and when you have expensive kois, the risk of getting them sick by introducing gambusia is not to be taken lightly.

    I don't worry about disease TOO much, as they are breed in fl. I don't think they have had to add any new ones in years... as long as there are two left before the weekend there will be enough to ship monday... or so it seems.

    Hello Timmychan

    Please think twice before using dimilin in any pond, while it may be a very effective poison for killing mosquitoe larvae, it kills many more things for a long time in water, including dragonfly larvae

    If you let dragonflies lay their eggs in your ponds, the baby dragonflies will eat all your mosquitoe larvae, very easily. Dimilin will kill the very thing that will naturally eat mosquitoes!

    A flying dragonfly might eat 200 mosquitoes a day, and the larvae of dragonfly will eat ALL the aquatic larvae of mosquitoe.

    If ever dimilin spreads from your pond to local streams it will kill many useful insects making the mosquitoe problem much worse, when the dimilin washes away the mosquitoes will rush in and 'explode' numbers with no natural predators to eat them

    Another simple natural way to keep mosquitoes away is to find a small type of fish, very tiny, which likes eating mosquitoe larvae that can live in the same pond as your koi

    Poisons, while they may seem to work very well for a time, often make a problem much worse, dimilin in even very small quantities kills many many good insects and crustaceans for a long time, making your pond, stream or lake a much poorer place

    Hi Andy,

    I have tried a few ways to rid the mozz, but to no avail. At the moment I have a few guppies (wild low quality type) to do the job. I introduced 3 female & 2 males 6 weeks ago & the result is promising. The guppies reproduced some young ones,but unfortunately the young ones are depleting by the days & I found a couple of the young fellow in my skimmer tank.

    Cheers

    Generally, the most common insect that swarms a pond & esp the filters are midge. They are attracted by foul water. This is a tell tale sign that your water is dirty and has decaying matters. Some mosquitoes are also attracted to such water conditions. Other types of mosquitoes only like clean water. If you keep your water clean and aerate your filetrs well, you wont have insect problems. I have not seen Midges ever since I became the enslaved koi keeper!Unimpressed

    >>what's the common denominator for ponds that seem to attract more mosquitoes than normal?

    The common denominator is a lack of natural predators.

    On any permanent healthy pond there is a wide range of natural predators such as water beetles, dragonfly larvae and small fish which ruthlessly eat every small insect like mosquitoe larvae

    However, with widespread use of poisons in agriculture and lawn products, many aquatic habitats are destroyed of natural species of insect. So polluted pools, temporary ponds, little puddles in the forks of trees, discarded litter like car wheels, tins and tubs that collect water long enough for mosquitoes to colonise, soon invade polluted ponds when the poisons have washed away

    A healthy diverse water garden is in effect going to destroy mosquitoes in large numbers...

    Here's a simple question:

    Where are you likely to see Mosquito Larvae?

    Standing Water?

    Moving Water?

    Mosquitos do NOT like to breed in moving water and that's why you most often see mosquito larvae in puddles, standing bucket of water ..etc. But seldom see them in moving water.

    Mosquitos can be erradicated with something called Mosquito Dunk .. or .. by natural predators such as "Mosquito Fish" which BTW multiplies like Rabbits! Buy a few Mosquito Fish and within just a few months you will have thousands of them!

    Bran,

    I wouldn't consider my pond water is moving, @ 5ft/min. Our pond water movement is limited to the length & breadth of our pond. However I am very sure that the mosquitoes larvae actually came into the filter drums via the main pond. For those filter that are not fully sealed may not see the amount of mosquitoes reproduced daily because once able to fly will be flown away. I am very sure about it because all my filter drums are fully capped plus a plastic mesh with rings to form a proper seal.

    There is no chance for a single mosquitoes to get into the filter drums to lay its eggs, the only way to get into the filter drums are from the pond. The amount of dead & alive mosquitoes found in the filter drums are unbelievable. I have to use maration spray ready when ever I want to open the filter drums.

    Normally I don't see any mosquitoes flying around, but I can only see spider web strategically built on 1 side of the pond. This means there are few flying around, like most of us don't see them until they bite.

    Recently I use local guppy (or may be is called mosquitoes eating fish). I think this fish helps. I can't confirm it now coz 2 weeks ago the town council guys spray the whole area with dangue mosquitoes chemical.

    The result is what I observed so far.

    Cheers

    I had a similar experience. This may be redundant to what others may have already told you... but her goes. I had a new pond last summer... with no fish in it yet. I noticed one day that the edgewater was thick with larvae. Since they take about a week to hatch, I rushed into action. I bought the reccomended number of BTI "mosquito dunk" donuts. BTI is a natural bacteria strain that is absolutely harmless to fish or anything other than mosquito larvae. In the larvae though, it multiplies and bursts their gullets. In our case, the outbreak was staggering, so I opted for the quick-treatment option: Instead of just floating them in the water, I crumbled the donuts up and sprinkled them into the edgewater. Four days later.... not a larva in sight.

    Some people have already mentioned the Mosquito Fish (Gambusia Affinis), but I have to tell you they are super efficient in eating those pesky larvae. I noticed that I had hundreds of mosquito larvae in my 200 gallon fishless pond and put about 10-15 of those mosquito fish in the pond and within an hour they had cleared ALL larvae from the pond. I take it you're from Kuala Lumpur, but for people in the US: You can get these fish for free from your local Fish and Game Store, or pick up a free bag at the Vector Control Center. If you're in LA go to: http://www.lawestvector.org/
