The Las Vegas Valley is dry, windy and under a federal plan for coarse dust. This guide explains where that dust ends up inside a Henderson house and the cleaning habits that keep it from taking over.
Dust is a constant in a desert home. A Henderson house can be wiped down on Saturday and show a film on the dark coffee table by Monday. That is not a sign of a bad cleaning job; it is what happens when a house sits in a valley with very little rain, very dry air and regular wind that lifts fine soil off open ground.
Here is what the local records say about dust in the valley, where it collects indoors, and a cleaning approach that works with the climate instead of against it.
Start with the rain, or the lack of it. Las Vegas Harry Reid Airport averages 4.18 inches a year, and May and June together see barely a tenth of an inch. Dry ground gives up its top layer easily, and dry air keeps the particles aloft. Average relative humidity is about 16.5 percent in June and 21.1 percent in July, and on some days it falls below 10 percent.
Wind finishes the job. Clark County air quality planners keep a list of high-wind PM10 events, the coarse dust that wind lifts from soil, including May 28 to 29, 2022 and July 31, 2023. The Las Vegas Valley is under a maintenance plan for PM10, and the National Weather Service office in Las Vegas issues Dust Storm Warnings for Clark County, divided into smaller alert areas since June 1, 2021.
Smoke adds a finer layer on top. County records list wildfires among the natural events that have affected local air, including August 18 to 21, 2020. Smoke particles are smaller than wind-blown dust and leave a gray, slightly greasy film rather than grit.
Desert dust follows air movement. It comes in around doors and windows on windy days, rides in on shoes and pets, and gets pushed around by the air conditioning, which in a valley with about 78 days a year at 100 degrees or more is running for a large part of the year. It lands wherever the air slows down.
Damp beats dry. A feather duster or dry cloth mostly moves desert dust into the air, where it settles again within hours. A barely damp microfiber cloth holds it. The same goes for floors: a damp mop after vacuuming picks up the fine layer a vacuum leaves on tile.
Top to bottom. Clean fans, vents and high shelves first, then furniture, then floors last, so nothing falls on a surface that is already done.
Mind the filter. The air conditioner filter is the house's main dust trap. The Southern Nevada Health District advises keeping it clean, and in a home where the system runs for months at a stretch, a clogged filter means more dust in every room.
Stop it at the door. Mats outside and inside every exterior door, and a shoes-off habit, keep a large share of yard grit off the floors.
During a dust storm warning or a high-wind day, keep doors and windows shut and wait for the wind to drop before cleaning; anything wiped mid-storm is dusty again by evening. Once it passes, start at the windward side of the house with sills, tracks and the floor just inside the doors.
Smoke calls for a different order. The health district advises against vacuuming when smoke is high, because it stirs up particles that are already inside. Keep the house closed, keep the filter clean, and wait until the air clears. Then wipe hard surfaces with a damp cloth first and vacuum afterward.
Because dust in the valley returns so quickly, frequency matters more than intensity. Every Recurring House Clean will dust reachable baseboards and blind slats as part of the visit, which is exactly where desert dust builds first. A bi-weekly plan suits most homes; homes with pets, desert landscaping or allergy sufferers often do better weekly through the windy and hot months. The recurring cleaning guide helps choose.
The high and hidden places need a periodic reset. A One-Time Deep Clean wipes ceiling fans, light fixtures and vents in place, wet-wipes blinds, hand washes baseboards and clears window tracks. A sensible rhythm is one in late spring and one after the monsoon. See the deep cleaning guide and the seasonal calendar for timing.
