Remember, standing water means mosquitoes. Any standing, stagnant water that remains for 7 to 10 days after a rain can, and usually will, produce mosquitoes. For example, one coffee can full of water has been shown to produce in excess of 10,000 mosquitoes over an entire summer season

Empty all water holding containers in your yard on a regular basis, at least once a week, children’s wading pools, rain barrels, buckets, bird baths and stored boats are prime examples of mosquito breeding sites.

Over-watering and poor irrigation practices are common producers of mosquitoes around the home, in parks and on golf courses. Report standing water to appropriate maintenance personnel.

Clean out eaves troughs and down spouts of leaves and other debris that slows drainage.

Ditches must be kept free of vegetation and other debris to promote rapid drainage, and pond edges should be kept clean of cattails and other aquatic vegetation. This is where mosquito larvae develop and mature. To reduce the number of adult mosquitoes in your yard:

Keep your lawn mowed as short as is practical.

Keep all ornamental shrubs and bushes trimmed and pruned to open them up to light and air flow. This will not only give mosquitoes one less place to hide, but will promote growth and vigor in the plant.

Cut back as far as possible, all low, dense under-growth surrounding your yard. This is where mosquitoes go to hide during the day.

Have large trees trimmed to allow sunlight to penetrate dark, damp areas.

Plan outdoor activities and parties during daylight hours or later in the evening. Many mosquitoes are most active at dusk and for about an hour after dusk.

The Skamania County Mosquito Control District supports management of vector populations when and where necessary by means of an integrated program designed to benefit or to have minimal adverse effects on people, domestic animals, wildlife and the environment. This Integrated Mosquito Management policy recognizes that vector populations cannot always be eliminated, but often must be suppressed to tolerable levels for the well being of humans, domestic animals and wildlife. Selection of scientifically sound suppression methods must be based upon consideration of what is ecologically and economically in the long-term interest of humankind.
The following principles are followed by your District:
• Vector control measures should only be undertaken when there is adequate justification based upon surveillance data.

• The combination of methods for vector control should be chosen after careful consideration of the efficacy, health effects, ecological effects and cost versus benefits of the various options; including public education, natural and biological control, elimination of the breeding sources, and pesticide applications.

• Vector breeding sources, whether natural or created by human activity, should be altered in such a manner as to cause the least undesirable impact on the environment.

• Pesticides and application methods should be used in the most efficient and least hazardous manner in accordance with all-applicable laws, regulations and available scientific data. The registered label requirements for pesticide use should be followed. When choices are available among effective pesticides, those offering the least hazard to non-target organisms should be used. Pesticides should be chosen and used in a manner that will minimize the development of resistance in vector populations.
