View Full Version : Mosquitos

Are mosquitos a problem in water gardens? I wouldn't think they would be as long as there was good water movement and it was deep enough. Do fish help?

Two main keys to minimizing mosquito problems:

1. design the water feature such that small fish or predatory insects ( ie damsel and dragon flies) can access all of the shallow areas.

2. maintain an aerobic environment. A little water movement will take care of this aspect.

If you have both of these bases covered, you would be hard pressed to find any mosquitos after fish are added or a permanent population of predatory insects develop. Of course if the pond is poorly designed and needs to be drained or cleaned periodically (annually), the insect population will not be of much help since it takes most of a year for these particular insects to develop into effective mosquito predators.

With the advancing wave of west nile virus, this is a very important aspect of aquatic design to consider!

From what I've read about the West Nile virus and how it spreads, it will just be a matter of time before we all contract it. It supposedly is passed on to the baby mosquitos by their infected mother and if an infected (carrier) mosquito bites an animal and then later another mosquito bites the animal... that mosquito then becomes a carrier. By the way... they say that the only people that have to fear the West Nile Virus are the very young, the old, and the weak. All other people that contract this virus will come down with flu-like symptoms.

The virus isn't the problem I was eluding to... lawyers of wnv victims are! We have significantly raised our rates for projects in public areas because of this.
