Mosquito bites are more than an irritation—they can cause serious illnesses that sometimes turn fatal.
West Nile virus (WNV) is a disease caused by a virus that is spread through mosquito bites. While many people may not have any symptoms, others can become very ill and even die from the virus. In 2021, more than 1,400 cases were recorded in Maricopa County.
We are working hard to keep mosquito populations from growing.
But the key to staying healthy is preventing mosquito bites – that’s where you can help!
Remember the 4rs to fight the Bite
One mosquito. One bite. That's all it takes to change someone's life forever.
WHAT YOU CAN DO
You can help prevent mosquitoes from breeding simply by depriving them of water, which they need to breed. Tip and toss even the smallest amounts of standing water from your home and yard. Plant pots, bird baths, kiddie pools, buckets and fountains are some of the places where
mosquitos can breed. View the backyard checklist and
