Mosquito breeding around the home can be reduced significantly by reducing the amount of standing water available for mosquito breeding. Below are some ways to achieve this.

• Dispose of tin cans, plastic containers, ceramic pots or similar water-holding containers that have accumulated on your property. Do not overlook containers that have become overgrown by aquatic vegetation.
• Pay special attention to discarded tires that may have accumulated on your property. The used tire has become the most important domestic mosquito producer in this country.
• Drill holes in the bottom and elevate recycling containers that are left out of doors. Drainage holes that are located on the sides collect enough water for mosquitoes to breed in.
• Clean clogged roof gutters on an annual basis, particularly if the leaves from surrounding trees have a tendency to plug up the drains. Roof gutters are easily overlooked but can produce millions of mosquitoes each season. Homeowners should also check the gutters in the spring to remove winter debris before the season starts and often in the fall when tress begin to lose their leaves.
• Turn over plastic wading pools when not in use. A wading pool becomes a mosquito producer if it is not used on a regular basis.
• Turn over wheelbarrows and do not allow water to stagnate in bird baths. Both provide breeding habitat for mosquitoes.
• Aerate ornamental pools or stock them with fish. Water gardens are fashionable but become major mosquito producers if they are allowed to stagnate.
• Clean and chlorinate swimming pools that are not being used. A swimming pool that is left untended by a family that goes on vacation for a month can produce enough mosquitoes to result in neighborhood-wide complaints. Be aware that mosquitoes may even breed in the water that collects on swimming pool covers.
• Use landscaping to eliminate standing water that collects on your property. Mosquitoes will develop in any puddle that lasts more than 4 days.
• Maintain mechanical barriers (i.e., window and door screens) to prevent mosquitoes from entering buildings. Barriers over rain barrels or cistern and septic pipes will deny female mosquitoes the opportunity to lay eggs on water.
