What's active right now

Floodwater and container mosquitoes are active and building toward the summer peak. Aedes vexans (the floodwater biter) surges about a week after heavy rain, and the Asian tiger mosquito is out biting during the day around homes. Early summer is when nuisance biting takes off.

Local mosquito habitat

Mosquitoes breed in standing water, so a town's risk tracks how much of that it holds. Rowland Heights is 0% wetland and marsh, 0% open water, and 45% developed across its 13.08 sq mi, home to about 48,231 people. That makes it the 93rd-wettest of the 141 towns in Los Angeles County. Marshes and floodplains breed the floodwater and cattail mosquitoes; developed areas breed the house mosquito in storm-drain catch basins and backyard containers.

The single biggest thing a homeowner controls is standing water: empty anything that holds it, keep gutters clear, and change bird baths weekly. A licensed mosquito service handles the breeding sites you can't reach and treats the shady resting spots where adults wait out the day.

How much does mosquito control cost in Rowland Heights?
