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.
