By Claire WhitakerA broom and dustpan needs no power and suits everyday dry debris on hard floors. For some messes, though, U.S. agencies say sweeping is the wrong move because it can put hazardous dust back into the air. This guide sets out those cases, using the EPA’s guidance on broken CFL bulbs, lead dust and asthma triggers, and San Diego County’s wet cleaning method for rodent droppings, along with what each one says to do instead.
When you should not reach for a broom
Certain messes call for methods that avoid stirring up dust or spreading contamination. The table below summarizes situations where dry sweeping is not recommended, based on guidance from the EPA and San Diego County Department of Environmental Health.
| Situation | Sweep? | What the agency says to do instead |
|---|---|---|
| Broken CFL or mercury-containing bulb | No | According to the EPA, you should have people and pets leave the room, air it out, and collect stiff paper or cardboard, sticky tape, damp paper towels, and a sealable container. Scoop up glass fragments and powder with the stiff paper, use tape to pick up small pieces, and wipe hard surfaces with damp towels. Place all debris and cleanup materials in a glass jar with a metal lid or a sealable plastic bag. Do not vacuum unless broken glass remains after all other steps, and then only with a window open and using the vacuum hose. Seal the vacuum bag or debris and dispose of it outdoors. |
| Rodent droppings, urine, or nesting materials | No | San Diego County’s wet cleaning method says do not stir up dust by sweeping or vacuuming. Air out unused rooms or buildings that have been empty for a long time by leaving doors and windows open for 30 minutes, wear latex or rubber gloves and respiratory protection such as a face mask, and prepare a disinfectant solution (10 parts water to 1 part bleach) or use a commercial disinfectant. Spray the contaminated area, let it sit for 15 to 20 minutes, then clean with sponges soaked in the disinfectant. Place dead rodents, nesting material, and all cleaning supplies in a sealed plastic bag and throw it away immediately. After cleaning, wash your gloved hands, remove and throw away the gloves, then wash your bare hands. |
| Homes known or suspected to have lead-based paint (more likely if built before 1978) | No | The EPA states that settled lead dust can re-enter the air when the home is vacuumed or swept. It advises cleaning weekly, wiping hard surfaces with a damp sponge, cloth or paper towel, and wet mopping floors. On carpets and rugs, use a standard vacuum if there is no visible dust or debris from chipping or flaking paint, and a HEPA vacuum if there is, and do not dry sweep. Avoid vacuums with beater bars, which may wear away painted surfaces. |
| General dust to reduce asthma triggers | Not addressed | The EPA recommends dusting often with a damp cloth and using a vacuum with a HEPA filter on carpets and fabric-covered furniture. People with asthma or allergies should leave the area being vacuumed. Wash bedding in hot water weekly and use dust-proof covers on pillows and mattresses. |
The common thread is dust. The EPA notes that settled lead dust can get back into the air when a home is vacuumed or swept, and San Diego County says vacuuming or sweeping rodent waste can stir up dust that makes you sick when inhaled. So the agencies replace sweeping with damp wiping, wet mopping, sticky tape and stiff paper, or a HEPA vacuum where they say one is appropriate.
Matching the tool to the mess
For a household dealing with lead paint or allergies, the agencies point toward wet methods and HEPA filtration rather than dry sweeping. Our guides to mop types and vacuum cleaners cover those tools. The EPA’s CFL guidance also says that if vacuuming is needed to remove the last pieces of glass, you should keep a window or door to the outdoors open, use the vacuum hose if available, and remove or empty the vacuum bag or canister and seal it right away. Keeping your tools clean and stored properly is covered in our cleaning equipment storage and maintenance article.
Frequently asked questions
Can I sweep up broken glass from a shattered light bulb?
The EPA advises against sweeping broken CFLs or other mercury-containing bulbs. Instead, use stiff paper or cardboard to scoop up glass and powder, sticky tape to pick up tiny fragments, and damp paper towels on hard surfaces. Seal all debris in a glass jar or plastic bag and put it outdoors in a trash container or protected area. The EPA says vacuuming is not recommended unless broken glass remains after the other steps.
Is it safe to sweep mouse droppings in the garage?
No. San Diego County’s guidance says not to stir up dust by sweeping or vacuuming rodent droppings, urine, or nesting materials, which can carry viruses like hantavirus. The recommended method is to air out the space, wear protective gear, spray a disinfectant solution on the droppings, let it sit, and wipe with a soaked sponge. All waste and cleaning materials should be sealed in a plastic bag and thrown away.
How should I clean dust in a home with asthma or allergies?
The EPA’s asthma guidance says to dust often with a damp cloth and to use a vacuum with a HEPA filter on carpet and fabric-covered furniture, with people who have asthma or allergies leaving the area being vacuumed. It also recommends washing bedding in hot water weekly and using dust-proof covers on pillows and mattresses.
