Mosquito Killing Pond - FAST & CHEAP!

I brainstormed up this project when I got attacked to death by mosquitos on my front lawn, this summer.

It turns out the neighbors had left a garbage can full of water when they moved out. My husband dumped the water, but the damage was done and the buggers were buzzing all over us in the evenings.

Well, I decided to throw something a little earth-friendly together. Citronella wasn't acceptable, because I have dogs and that stuff is pure torture to their noses. Pesticides should be illegal, so I wasn't about to do that. This project is what I came up with.

Hope it works as well for you as it did for me!

This project should take you all of a half hour to assemble, and a couple minutes a week to maintain. The cost is ridiculously cheap. Time spent on getting supplies will vary. Ok, let's get started!

Step 1: Get it together...

Here are the items you will need:

1) Cat litter box OR another wide, shallow, waterproof vessel to contain your mosquito-eaters. Tall is no good. Without surface tension, the fish will die from oxygen deprivation. Just like with a fish tank... tall = less oxygen / wide = more oxygen. Heck, you could even use an old fish tank, if you have one lying around.

2) Water conditioner, to make the water safe for the fish. Read the instructions on the bottle. I eyeballed the measurements, once I had read the amount per gallon. It's not rocket science, so don't panic! Most pet suppliers will carry this sort of stuff as well. Inexpensive and a little goes a long way.

3) Guppies! You can get them at most aquatic-dealer pet shops, as they are used to feed to larger fish. They're also common as heck in ponds just about everywhere. They're those tiny tiny fish that crowd together and somehow manage to survive in the most stagnant looking waters. They cost about a dollar for a dozen. The amount you purchase will depend on the size of your container. Warning- They breed like mad. I wouldn't recommend starting with more than one dozen for most containers!

4)Plants. More on that later.

You could collect a bit of duckweed or other native species from your local pond or lake to make sure it will tolerate your climate. You could also try to get a live small bait species from the local sporting goods store to reduce the chances of introducing a non-native species.

My method is quite effective. I bo't a $10 semi rigid kids wading pool and put about 3-5" of water in it. The ladies lay their eggs in it, and as the wigglers develop I dump it on the lawn. This has to be done every three days before the wigglers can get airborne. I also add about a 1/4 tsp of dish detergent so there is no surface tension. Something else that is fairly effective is using a dome lidded barbecue with the small vent hole in the top. In late evening, get a bricket going in there. It gives off a little heat but it's greatest power is the carbon dioxide it gives off. Blood insects are attracted to CO2. A friend found her barbecue full to the top vent holes in the top, all dead. - thousands of them.

I'm actually really tempted to make a waterfall type pond on my back porch. We have mosquito's in our house and on the porch. They are everywhere right now. I live in Florida and they are around at least half of the year, if not more.

I wouldn't mind getting fancy guppies if we do a nice pond... then it would be worth keeping and taking care of. Either way, this is a great idea and I might be doing it VERY soon. I am so tired of getting bit by mosquito's!!! Ugh.

I don't think mosquitos would even lay in your pond if it has a water fountain, so it won't be a problem for you :) Mosquitos prefer to lay their eggs in stagnant water.

I live on a rock ridge, so all my gardening is done in raised beds and pots. For some reason or other this seems to attract a large number of dragonflies.

I don't worry about mosquito nymphs 'cause as soon as the little buggers take to the air my own personal airborne strike force takes them down.

'Course at night I get the benefits of my bat houses.

Then sometimes I set out containers of water and let the mosquitoes waste their eggs, because when the nymphs get to the hatching stage I use the water to keep my compost bins moist (and add some protein).

Can't get much lazier than that.

another way if keeping bugs away is useing marigolds. bugs dont like the smell. i use them in my food garden and they are great for tomatos! eather way its another poison free way to try to keep bugs away.
gemtree in reply to d2j5Aug 6, 2011. 8:50 AM
I bought lots of marigolds one year and the bugs ate them FIRST. Then when they decimated the marigolds, they ate everything else. *sigh* I learned that in Texas, grow spinach in the winter. NOTHING keeps the bugs off them in the spring/summer.
d2j5 in reply to gemtreeAug 8, 2011. 2:01 PM
im sorry it didnt work :/ it works up in mass. though
Tarantulady (author) in reply to d2j5Jul 28, 2009. 12:50 PM
Holy crap! I have to consider that for this year. I like flowers, and marigolds don't seem to get murdered easily by me. I never heard of this. Thanks!
d2j5 in reply to TarantuladyAug 5, 2009. 4:40 PM
i know that the sent from the marigolds doesnt have a wide range so you might need quite a few planters around a deck or sitting area to help
gemtree says: Aug 6, 2011. 8:59 AM
Hm, I really LIKE this idea. I have a hot tub in the back that I don't use. It is FULL of mosquito larvae. I treat it occasionally with Bacillus Thuringis. (sp?) That usually works but I just don't want to go buy another bottle of it. It is expensive. I am sure cheap fish food costs less.
gemtree in reply to gemtreeAug 6, 2011. 9:05 AM
I forgot to add, I make small cement watering bowls for animals. I suppose I could make much larger ones for a guppy/mosquito pond. Dig out a hole and line it with wire mesh and fill the mesh in with a cement and acrylic mix for waterproofing the cement for a low pond. Let it cure a few weeks then let it sit with water for awhile before putting in the fish. In Texas, we have mosquitoes all year round.

I have a friend that has a well with water just a foot from the top and his yard was filled with mosquitoes.
I went to a fish store and bought a dozen goldfish and a small can of food to ease the mind of my friends Dad.
I dumped the goldfish into the well and a month later there were no more mosquitoes. The well was 6 feet deep so the fish had lotsa room to move around.
The next spring the fish were bigger and just waiting for the bugs to drop by.
These feeder goldfish got to be 4 inches long and had babies.
I joked that they should sell tickets to go fishing.

i love ur idea! now THATs a good way to biologically control ur pesky skeeter population!
DIY-Guy says: Nov 1, 2010. 1:12 PM
Mosquito larva cannot breach the surface tension caused by vegetable oil on the surface of the water. They die without oxygen, they cannot leave the water as they mature. They get stuck at the surface film!

Cheap, "eco-friendly" and simple.

This works for watering troughs that do not constantly overflow, puddles, unwanted ponds, ornamental ponds, garbage cans, etc.

 dunno if you get a product called 'Dettol' in yr part of the world like we do in South Africa and Zimbabwe, but if you do, mix a 50/50 mix of dettol and water into a fine mist spray bottle and apply liberally to onseself for a mozzie free time!
StuNutt in reply to Ole ballySep 5, 2010. 11:17 AM
Ah, Dettol! But your wife/girlfriend won't come near you either :D
matrix828 says: Apr 12, 2010. 1:19 PM
your guppys will get killed by the fully grown mosquitos. the larvae will probaly kill them aswell. good idea tho. try piranahs next time ^.^

sorry, WRONG!!!!!!!

This is great. A long time ago when aquiriums were all the rage but electicity was not, the goal was a balance between plants and fish and the result was clear water and healthy fish. I did this same thing a few years ago with tadpoles (224 of them and don't ask me how I know) and was rewarded with a mosquito free back yard for about a year - this year's cold spell was the end of that though as I guess the frogs got wiped out. Thank you for a very creative idea. Feeder guppies in my town are 20 cents each.
Chewie42 says: Jun 18, 2010. 5:38 PM
you should rig up a solar powered air pump for the fishes..they would live longer cool project
Bigos says: Apr 7, 2010. 10:42 AM
Thanks for this project and thanks to all the others who posted other ways to kill the little buggers.

I can't remember who told me about this, but if you take a white plate and fill it about half full of water and put a drop or two of dishwashing soap into it the mosquitos will come by and get a drink due to their need for water, fly off about maybe ten feet and fall to the ground dead.  The soap kills them and one drink is all it takes.  The purpose of the white plate is to attract them so I'm told.  After use you can throw the soap on the lawn, it will only help loosen the soil, no harm done!  I would put the plate where pets can't get to it - if they drink the water it could cause them to get dirrhea, not a good thing.  If larvae are found in a puddle, adding a few drops of the soap will kill them also. 
When I was growing up we used a waterer for hogs that used an open top 55 gallon drum and we kept a small bottle of soap down there in case mosquitos laid eggs in the water there, add a few drops and the next day they're dead.

Search for Bat House- there are instructions (and probably instructables) online. Bats eat a LOT of mozzies.

Also, hang some hummingbird feeders. While they do love sugar-water, hummingbirds obtain their protein from eating small flying insects like gnats and mozzies. Planting hummingbird-friendly flowers will help as well.

Putting out ponds like yours will help reduce future generations, as will doing a sweep of the neighborhood for standing water. Be sure to check your gutters and any other areas where water can accumulate. Mozzies will breed in as little as a bottle-cap full of water, but simply *can't* breed unless they do have standing water.

If you want a bigger pondlet, you might add a simple air pump to move the water around a little. Aquarium stores sell pumps for $5-$10, add an airstone and some clear tubing and you've got a good way to agitate the water enough to make a big difference in the fishes health. Most pumps aren't waterproof, so protect it from the rain.

Cool, thanks for the pointers! Since I made this instructable, I moved homes and my boyfriend did plant some hummingbird plants and it definitely seems to make a difference. Plus they're way freaking cuter than guppies <_<
annchanted says: Dec 11, 2008. 11:34 AM
I like your idea. I have been an avid guppy keeper and breeder for a couple of years now. Guppies are known to eat several times their weight in mosquito larva every day. However, guppies are not the same thing as the dollar-per-dozen "feeder fish" you mentioned that are fed to larger fish. Guppies are prized by many aquarium keepers and cost approximately $2 to $4 per fish. Either way, with guppies or feeder fish, you should have pretty much the same result. Great idea!
Tarantulady (author) in reply to annchantedAug 26, 2009. 1:47 PM
Where I live, we have 3 common kinds of feeder. Feeder "comets" (the un-fancy goldfish), feeder "rosies" a type of cultivated minnow, and feeder guppies. The feeder guppies are the natural ones that aren't fancy and don't have the awesome sexy fins. They sell them for smaller carnivore fish and also for firebelly toads bc it's hilarious when they eat them. I think maybe they don't sell the same feeders in different areas bc of the climate or something.
nekoheehee in reply to annchantedJan 21, 2009. 3:49 AM
see now that's kinda funny because you're both right. my mom used to breed guppies for years and years and she had some nice colorful prize winners (at local fairs and what not). but then we've also gotten bland dull guppies at pet stores for next to nothing. It really depends on the breed and where your shopping.
Tarantulady (author) in reply to nekoheeheeJan 22, 2009. 8:05 AM
Everyone's right! XD They're the same exact species. One is the dull, drabber natural form of the animal (although the males are still pretty if you look closely)... The other is the more cultivated form. The natural form is more hardy because the fancy ones are mutants ;) I wouldn't spend the money on the fancies for a pond, since that could get expensive as heck and they aren't very tough!
annchanted in reply to nekoheeheeJan 21, 2009. 6:43 AM
I think the guppies you are talking about are what we call in my area "feeder fish," which are little ten-for-a-dollar fish that you use to feed other bigger fish. I guess some people call them guppies, but, in this area, the only fish we call "guppies" are the pretty, colorful ones with the flowing tails and fins who give birth to live babies as opposed to laying eggs, which I believe the feeder fish lay eggs. They are actually part of the koi family. It probably just depends on what are you live. Let's just chalk it up to that.
nekoheehee in reply to annchantedJan 21, 2009. 2:15 PM
No, I vividly remember the live birth of the "not so colorful guppies" and my mom cross breading colorful and not colorful. we also had a mixture of wild and domestic guppies in our tank and there is a visible difference with some breeds. my mom claimed that the wild ones weren't so inclined to die from temperature shift and made for a healthier breed. I respectfully stand my by "depends on the breed and where you shop" statement. but in the end I think feeder fish would work better in some cases then your average domestic guppy. feeder fish have a higher tolerance to temperature change and can resist sickness better then guppies. random note: I once saw a gold fish for $200. I asked the clerk at the pet shop "what is it made of gold?!" he said he had no idea why so much but was willing to bet it granted wishes.
Rotten194 in reply to nekoheeheeMay 31, 2009. 2:36 PM
And you could hook up internet for your $200 Miracle goldfish with this so he can communicate with his worshipers.
Tarantulady (author) in reply to Rotten194Aug 26, 2009. 1:48 PM
lol
annchanted in reply to nekoheeheeJan 22, 2009. 6:27 AM
You are correct that the feeder fish are much hardier. I had one that I picked up just to see what it grew into and it lived longer than any of my other fish.
Tarantulady (author) in reply to annchantedDec 17, 2008. 10:38 PM
Thanks! I swear the animals I am using are guppies :o They just aren't the cultivated, fancy ones! They are the common, wild form. They use them to feed to small predatory fish in the pet trade, although many places don't carry them, but instead carry comets (common gold) and rosy red minnows, etc. I would never use the $2-$4 guppies, because they're so fancy I just can't bear the thought of putting them outside where I can't see them, lol. I live in NJ. Maybe they're more expensive for you where you live? If they aren't guppies, I would be shocked, because they look identical to the fancy guppies except very plain, etc. Now I'm totally intrigued and I'll have to look into similar species and see if the common name doesn't cover them. :o Thanks for the food for thought n_n

You might consider using the mosquito larvae as an asset. Back several years ago when I was keeping several tanks running I would harvest mosquito larvae and feed it to my fish. I set up a couple of mosquito hatcheries out of old plastic garbage cans. I'd put some dead leaves in the bottom then put the water in. You want to put the hatchery out of where it will be receiving a lot of direct sunlight. Too much heat and your water won't have the bacterial bloom the potential mother mosquito is looking for. After waiting and watching you should start seeing mosquito larvae coming to the surface to breathe. Its a simple matter to dip them out with a fine fish net. I would usually rinse them off before feeding to the fish. Angel fish, in particular, seemed to relish the larvae. If you are diligent in your harvesting you will not be adding to the mosquito population, in fact, you will be removing many mosquitos from the surroundings. After the hatchery had run a few weeks I would make one last harvest and then dump the remaining water and dead leaves on the lawn. Any remaining larvae would soon dry out and shuffle off this mortal coil. I would then gather some fresh dead leaves, and start the cycle all over again. Oh, and when you are harvesting the most mature larvae have a decidedly comma look to them. Those are the ones you especially want to get. I did this before the problems with avian flu and West nile virus. This could possibly constitute a danger but so long as you practice good hygene regarding the aquarium I don't think it will be any problem. Also in the years I did this I never ran across a mosquito in the house. The fish took care of all of the larvae.

We now have a 180 gallon aquarium so this idea is awesome. Thanks so much bc it's more fun (and cheaper) than getting frozen bloodworms all the time.

BT is right. Most folks don't have access to " mosquito fish. I am lucky enough to live in an area that they are native to. The common pond or lake guppy is tough enough to survive our local temperature swings. I do bring them in if it gets down into the 20f. I went one set further by building a solar powered fountain, complete with running streams, water falls and a mill with a turning water wheel. All this action quits when the sun goes down and the "skitters " come out and find the calm waters to lay their eggs. It's a cute double duty mosquito trap full of hungry mouths. And yes I am sorry I didn't make an instructable out of it.

I work in a pet shop, so I'm actually going to see if I can order these through our supplier. Thanks for the tip.
