Stagnant water is water that remains in an area for more than one week (7 days or more) and is not flowing or subject to wind or wave action.
If the stagnant water cannot be removed, (as in catch basins, ditches, ponds, etc.) these areas are monitored for the presence of mosquito larvae.

Stagnant water includes water in rain gutters, discarded tires, ornamental ponds, puddles, rain barrels, flood water pools and roadside ditches (if the property owner is responsible for the ditch and it has no flowing water).
It the container or stagnant water body cannot be emptied or drained then larviciding may be an option.

 News Release: TDH Urges Swimmers to be Cautious in Lakes, Rivers, Stagnant Water   (Site not responding. Last check: 2007-11-05)
The infection, primary amebic meningoencephalitis or PAM, is caused by a common microorganism found in almost all untreated surface water and in soil.
The combination of lower water levels, high water temperature and stagnant or slow moving water produces higher concentrations of the amebae in the water, said Neil Pascoe, of TDH's infectious disease epidemiology and surveillance division.
The PAM infection occurs when water containing the organisms is forced into the nasal passages -- usually from diving or jumping into water or water skiing.

In reality, there are no magic bullets, but although draining stagnant pools or treating them with a pesticide remains the most effective means of controlling mosquito populations, there are biological controls that will help lower insect populations, said Dr. Billy Higginbotham, wildlife and fisheries specialist with Texas Cooperative Extension.
"The stagnant water sources such as birdbaths left unattended, old tires and cans are probably more of a problem since they don't already contain fish — and it's doubtful that stocking fish into stagnant water will result in very good survival.
The best bet remains to use biological control measures in conjunction with draining stagnant water sources, and using environmentally safe insecticides such as Bti when necessary.
