Since the immature stages of mosquitoes breed in standing water, all such sources should be eliminated around residential and commercial properties. Any container holding water should be covered, removed, emptied or stored upside down: rain barrels, unused swimming pools, animal watering troughs, wading pools, neglected hot tubs, barbecues, stationary vehicles, stored boats, flower pots, glass jars, tarps, buckets, wheelbarrows, ornamental ponds, discarded tires, clogged rain gutters and birdbaths.
Fresh water minnows and gold fish eat mosquito larvae, and can be added to permanent ponds.
Irrigation water should be managed, to prevent standing water from lasting more than three days.
Plants and lawns should not be over-watered.
Leaky faucets or air conditioning units should be repaired.
Removal or pruning of dense shrubbery and vines, to permit the entry of sunlight, will reduce mosquito resting sites.
The mosquitoes that are known to transmit the Zika viruses (Aedes aegypti and Aedes albopictus) ARE NOT established in the Grand Valley. The Center for Disease Control has issued a travel warning to pregnant women that plan to travel in areas where the Zika Virus is endemic. For more information go to www.cdc.gov/zika/.
