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. Big Timber is 0% wetland and marsh, 4% open water, and 39% developed across its 0.98 sq mi, home to about 1,686 people. 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.
