Leftover rainwater from recent summer storms can create a perfect breeding ground for disease-carrying mosquitoes.
To limit the risk of West Nile virus, Maricopa County Health officials suggest homeowners eliminate standing water left in tires, plastic containers, or any container that can hold water.
Health officials say abandoned homes with stagnant swimming pools can become ideal habitats for mosquitoes to breed.
The symptoms of West Nile virus include fever, muscle aches, headache, a tired feeling and in some cases a skin rash.
While the illness can be as short as a few days, even healthy people have reported being sick for several weeks.
