Q: We love sitting by our pond, but the mosquitoes are active this year. How can we control them

Scott – Tampa, FL

A: There’s nothing as irritating as a mosquito. They buzz, they bite, they feed on blood, they leave behind itchy welts and, in some cases, transmit dangerous diseases like malaria, dengue, yellow fever, West Nile virus, dog heartworm and equine encephalitis. No, they’re certainly not a welcome pondside guest!

Controlling these tiny bloodsuckers requires a four-pronged approach. Here’s what we recommend:

1. Move the Water: A female mosquito prefers to lay her eggs in stagnant water that’s full of algae, plankton, fungi and bacteria, so your first priority should be moving your water with an Airmax® Aeration System near the area where you sit. The agitated water will make her think twice about calling that part of your pond home.

2. Destroy Their Habitat: When the mosquito larvae—or wigglers—hatch, they nibble on all those tiny plants and microorganisms that are floating by as they develop into pupae—or tumblers—and, eventually, adults. So the second item on your to-do list is to cut down on all the debris around the edge of your pond, or at least in the area where you hang out the most, with a pond rake and weed cutter.

3. Put Mosquito Fish to Work: If you don’t already have a fish population living in your lake, consider adding some mosquito fish, which are small fish that gobble the wigglers and tumblers. The American Mosquito Control Association recommends adding predacious minnows or native fish to lakes and ponds for biological control of the insects.

4. Use Mosquito Dunks: If you find you’re still having problems with the vampire bugs, try some Summit® Mosquito Bits® & Dunks®. These handy-dandy little disks and crumbles contain Bt-israelensis (Bt-i), a specially formulated biological pesticide designed to destroy mosquitoes. You simply toss them in your pond or lake and they’ll provide relief for up to 30 days. Plus, they’re safe for use around fish and plants.

Unfortunately, mosquitoes are part of life with a lake or pond. But with a little aeration, physical control, biological control and, if necessary, chemical control, you can keep these irritating bloodsuckers managed so you can enjoy relaxing evenings by your pond.

  1. Thanks Greg… Happy Pondering…. Nelle

  2. NELLE ,YOUR QUESTION ABOUT GOING IN POND WATER MY VERY ON THE CONDITION. MINE, I GO IN. I EVEN HAVE NEIGHBORS ASK IF THEY CAN GO IN, I SAY OK, JUST DON’T CHASE HE FISH OR
    DISRUPT THE PLANTS. THERE MAYBE AT TIMES WHEN ADDING CHEMICALS I DON’T WANT THEM IN. WITH THE PEE GRAVEL AND RIVER ROCKS THERE ARE NO SHARP EDGES. NO WALKING ON THE WATER FALL. OTHER WISE IT IS OK. I GIVE THE POND CHEMS.
    TO WORK, FOR 2 DAYS BEFORE. REMEMBER MINE HAS A LINER.
    WE HAVE NEVER HAD A PROBLEM. I GO IN AND REPLANT MY PLANTS ALL THE TIME. KOIS WILL MOVE AROUND IRISES. GOLD
    FISH ARE VARY DESTRUCTIVE TO PLANTS. MAKE SURE NO KIDS
    PEE IN THE POND, IT BREAKS DOWN A POND VERY FAST. I DON’T HAVE KIDS JUST MY WIFE. SHE SITS WITH HER FEET IN IT. ADD
    ACUU CLEAR OR AQUA CLEAR ONE DAY LATER. THAT HELPS RE-BALANCE YOUR POND BACK , IF YOU THINK IT IS DIRTY FROM THEM WALKING AROUND IN IT. A SLUDGE ADDITIVE, I ADD IN THE FALL. WHEN THE DUCKS ARE GONE SOUTH , THEN I ADD IT.

    I HOPE THIS GIVES YOU AN IDEA OF WHAT , I DO. GOOD LUCK!!!

    • Greg, you are as handy as a watch pocket on overalls, You have given me such good info… I just wanted to make sure the koi poop wouldn’t be unhealthy. I am going to revamp my plants and thanks to your info, I’m going to play in the pond on Saturday ( I won’t do much playing but a lot of work) Oh by the way, we don’t allow animals or kids in the pond..I’m off to home depot to get more pea gravel and rocks. Nelle

      • NELLE, WHEN YOU GO IN A LAKE, DO YOU SEE WHAT YOU ARE WALKING ON?!! THE MUD BOTTOM THEIR IS THE SAME AS IN MY POND, BUT MINE IS CLEANER BECAUSE CHEMICALS ARE ADDED !! SO WHICH WAY DO YOU GO, IN OR OUT!! ME, I GO IN !!! YOU ARE
        NOT DRINKING THE WATER EITHER WAY. DOGS THAT HAVE GONE
        ACCIDENTALLY HAVE NOT GOTTEN SICK. THEY JUST GO BACK IN FOR MORE,UNTIL I CHASE THEM OUT. THEN I GO BACK IN TO
        REARRANGE MY PLANTS IF NEED BE. I HAVE NEVER WORN WADERS UNLESS THE WATER WAS VERY COLD, EARLY SPRING.
        NELLE ,EVER DAY I AM LEARNING SOMETHING NEW ABOUT MY POND. A LOT OF THINGS I END UP DOING ARE TRIAL & ERROR.
        YOU CAN NOT BE AFRAID TO TRY NEW THING, JUST REMEMBER WHAT WORKS & WHAT DOES NOT!!! FOR ( 8 ) YEARS I HAVE BEEN EXPERIMENTING DIFFERENT THINGS,AND STILL LEARNING.
        THERE IS ALWAYS SOMETHING NEW GOING ON,FISH,PLANTS ,PUMPS WATER CONDITION,LIGHTS,AND ALGAE. OH,THE OTHER THING I FOR GOT IS NIGHTLY CRITTERS TRYING TO GET IN IT.

        ALWAYS SOMETHING !!! YOUR PONDERING FRIEND – GREG

  3. NELLE , IT HAS A LINER , IT IS MAN MADE. IT IS 25 X 19. IT HOLDS 3,000 GALLONS OF WATER,IT CIRCULATES 5,000 AN HOUR. THERE IS 8.5 TONS OF ROCK IN IT. THEY USED A BACK HOE TO PACE THE BOLDER’S AROUND IN IT. THE SHALLOW END IS 18 INCHES. THE DEEP END IS 5 FT. THERE ARE 6 8 – 7 3 KOI’S , 1 5 DIFFERENT KINDS OF WATER LILY’S. PATTI HAS 3 0 DIFFERENT KINDS OF HOSTA’S SOME ARE 7 – 7 1/2 FEET ACROSS. THE HOSTA’S HOLD THE HILL TOGETHER FOR THE WATER FALL THAT IS 18 FEET LONG. THERE IS A BUBBLING WATER FALL ROCK AT THE FAR END THAT IS 5 FEET ACROSS. THERE ARE 5 UNDERWATER LIGHTS AND 6 ABOVE GROUND LIGHTS. THERE ALSO IS A WOODEN SWING TO SIT IN A THE OPPOSITE SIDE OF THE ROCK. THE 8.5 TONS OF ROCK DOES NOT INCLUDE THE WATERFALL NOR THE BRIM. THE BRIM IS 2 1 /2 FT HIGH SO THE RACCOON’S CAN NOT GET IN TO IT. THEY DON’T WALK DOWN HILL, TOO STEEP. RACCOON’S ARE ALSO NOT DIVERS.!!

    NELLE , I HOPE THIS GIVES YOU AN IDEA OF OUR POND !!!! I HOPE ALL YOU OTHER PONDERS HAVE AS MUCH FUN YOURS, AS WE DO.!!!

    • Sounds beautiful… Greg, is it safe to go into the water without waders? I’ve always jumped in and re-arranged the plants with no side effects, but someone told me it was not healthy to get into pond water…I will be in the water re-planting My Iris and water lillies. I love my Koi, they are so pleasing… they don’t bark, yell or scream at you… they appreciate all those little pellets. LOL Thanks for your info… Nelle

      • NELLE , THE OTHER REASON THAT KOI MOVE PEE GRAVEL AROUND IS FOR RUBBING THERE SCALES AGAINST THE ROCKS, FOR CLEANING SLIME OFF, IN OTHER WORDS FOR SCRATCHING AND MAKING A NEST. EVEN THOUGH THEY ARE LIVE BERING.
        I HAVE TO RE SHOVEL MINE BACK ONTO A LEDGE FOR MY WATER LILY’S EVERY YEAR. I HAVE ( 4 ) LEDGES OR STEPS.
        I BORDER THE PEE GRAVEL, AROUND THE LILY’S WITH RIVER ROCK AND LAY A LAYER ON TOP ALSO, SO THE PLANT DOES NOT MOVE OR FLOAT AROUND. MAKE A BORDER YOU WILL BE GLAD YOU DID.

        GOOD LUCK ,IT DOES HAPPEN ALL THE TIME.

  4. AS FAR AS MOSQUITOES GO. WE PLANTED CITRONELLA LEMON BALM PLANTS & WE SIT THERE UNTIL 10:30 OR 11:00 PM. NONE AROUND,MAYBE 1 OR 2 THAT IS IT. WE LIKE IT, IT WORKS WELL. WE EVEN GIVE SOME TO FRIENDS. IT IS AGGRESSIVE BUT WHO CARES. IT SMELLS & TASTES LIKE LEMON. BEATS SPRAYS.

  5. Thanks Greg, I’ll check that out.. As for the dirt, it was in the pond before I found out that you didn’t need a lot of soil… especially if you have Koi… they love the mud…I’ll check out the Accu Clear…By the way, the pot that turned over during a wind storm had been in the pond about 6 years and the Iris were huge, overturning and breaking the plastic pot… the koi has has a great time doodling.

    • We do not sell AccuClear but we do sell a similar product called Clarity Defense (http://www.thepondguy.com/product/pond-logic-clarity-defense).

    • MY IRIS ARE UNDER PEE GRAVEL AND RIVER ROCK.
      I PUT MY MINI CATTAiLS IN A POT WITH NO EXTRA MUD,JUST ENOUGH TO COVER THE ROOTS. THEY ARE CONTAINED & ARE 5-51/2 FT.TALL. IF U WHERE TO MAIL ME I WOULD SHOW U MY POND SO U WOULD HAVE SOMETHING TO COMPARE TO. WITH LARGER RIVER ROCKS AROUND THE IRIS THEY ARE NOT OVER GROWING MY POND. I HAVE NEVER DISCARDED ANY.I HAVE TRIED TO LEAVE IT ALL NATURAL. SOME PLANTS ARE IN POTS,THE ZEBRA TAILS ARE VERY AGRESSIVE , THE GREEN & WHITE STRIPS ARE.

    • IF YOU ARE GOING TO POT PLANTS, POND GUY HAS GOOD ONES OR GO TO THE STORE U GET YOUR POND SUPPLIES
      FROM,THEY LOOK LIKE A MESS SCREEN. IT HOLDS THE ROCKS WELL. MAKE SURE U SPRAY THE ROCKS IN THEM WITH A LOT OF WATER TO CLEAN THEM OFF. SMALL KOI WILL DIE FROM EATING THE DUST GRAVEL. CLEAN THE ROCK OFF WELL FROM THE BAG.
      THE DUST IS THE BAD PART. I EVEN SUBMERSE THE BASKET IN A GARBAGE CAN AFTER SPRAYING THEM. LET IT DRY.LEAVE A SMALL HOLE ABOUT HALF WAY.2-3 INCHES FROM THE BOTTOM.
      PUT A FERTILIZER TABLET IN THE HOLE OR PRESS IT INTO THE BOTTOM OF THE PLANT THEN ADD THE REST OF THE DRIED
      ROCKS. AROUND IT TO HOLD IN PLACE. THE BIG RIVER ROCK, ONES GO ON TOP TO HOLD IT DOWN. PENDING ON THE SIZE
      OF PLANT, MY MINI CATTAILS POT, THERE IS 4 INCHES OF TOP ROCK TO HOLD IT DOWN. IT WILL GROW TALL ,BUT WILL NOT SPREAD. MAKE SURE IT IS ON A SOLID BOTTOM.THAT WAY THE WIND WILL NOT BLOW IT OVER. FOR IRISES I USE A FINE CRUSH ROCK. THE ROOTS WILL NOT PENETRATE THE CRUSH ROCK.
      ADD LAGER RIVER ROCKS ON TOP,TO HOLD FROM FLOUTING
      AWAY.

      I HOPE THIS GIVES YOU AN IDEA. G O O D L U C K !!

    • JUST TO GIVE YOU AN IDEA, I DON’T TAKE FISH OR PLANTS OUT OVER THE WINTER. IF THE PLANT DIED CUT OFF THE DEAD, REPLANT IT IN WATER IT WILL GROW. I LIVE IN ROCKFORD 9 0 MILES NORTH WEST OF CHICAGO AND IT GETS COLD HERE. DO NOT FEED FISH UNDER 5 2 DEGREES WATER TEMP. THEY WILL LITERALLY BLOW UP, THEY CAN NOT DIGEST FOOD AT THAT TEMP. EVEN IF THE BAG SAYS OK, JUST DON’T,
      BEING SAVE IS BETTER THEN SORRY !!! THE WATER HAS TO BE AT LEAST 2 1 / 2 FT TO DO SO. MY POND WAS 12 INCHES THICK OF ICE, ONE YEAR . ALWAYS RUN A DEICER IN THE WINTER AERATE IF POSSIBLE, ALSO.

      ENJOY YOUR POND !!

  6. What is the highest rated pond vaccum with an affordable price… I can’t go over $200 dollars. My pond is approx 2300 gallons and 32″ inches deep. I have two 30 inch Koi And they are 12 years old. I have managed to keep the water good until a pot turned over and the Koi grabbled out all the dirt and Pea gravel. I need a vac that will be stong enough to pull up mud. What’s your suggestion?
