- Duct tape or masking tape
- Mercury spill kit (if available) – often contains sulfur powder.
- Carefully Collect the Mercury: Use the eyedropper or syringe to collect visible beads of mercury. Gently push beads together using the cardboard or squeegee to make them easier to collect.
- Place Collected Mercury in a Sealed Container: Carefully transfer the collected mercury into the sealable container. Label the container clearly as “Mercury – Hazardous Waste.”
- Address Small, Hard-to-Reach Beads: Use duct tape or masking tape to dab up any remaining small beads of mercury. Place the used tape in a sealed plastic bag. A flashlight held at an angle can help reveal hidden droplets.
- Apply Mercury Binding Agent (Optional): If you have a mercury spill kit, use the sulfur powder or binding agent according to the manufacturer’s instructions. This will help to solidify any remaining mercury.
- Clean the Area Thoroughly: Wipe the affected area with a damp cloth. Place the cloth in a sealed plastic bag.
- Proper Disposal: Do not throw mercury, contaminated materials (gloves, cloths, tape, etc.), or containers into the regular trash. Contact your local waste management authority, environmental agency, or health department for information on proper disposal methods. This is crucial!
- Monitor for Lingering Vapor (Optional): Mercury vapor analyzers are available for rent or purchase. These devices can help detect the presence of mercury vapor in the air after cleanup. If vapor levels are elevated, further cleanup or professional remediation may be necessary.
- Wash Your Hands Thoroughly: After cleanup, wash your hands thoroughly with soap and water.
Items to Avoid During Mercury Cleanup
Certain actions can worsen a mercury spill:
- Vacuuming: Vacuums can spread mercury vapor and contaminate the vacuum cleaner.
- Sweeping: Sweeping can break mercury into smaller beads and disperse them further.
- Using a Broom: Similar to sweeping, brooms spread the mercury.
- Washing Clothing in a Washing Machine: This can contaminate the washing machine and release mercury into the wastewater system.
- Pouring Mercury Down Drains: This can contaminate the plumbing and the environment.
When to Call a Professional
While the above steps outline how do I get rid of mercury in my house? safely, there are situations where professional help is necessary:
- Large Spills: If the spill involves a significant amount of mercury (e.g., from a broken barometer).
- Hidden Spills: If mercury has spilled into cracks, crevices, or porous surfaces that are difficult to clean.
- Unsure About Cleanup: If you are unsure about any aspect of the cleanup process.
- Symptoms of Mercury Poisoning: If anyone in the household is experiencing symptoms of mercury poisoning.
- Failed DIY Attempts: If your efforts to clean up the mercury have been unsuccessful.

Frequently Asked Questions (FAQs)
How much mercury is considered a dangerous spill?
Any amount of mercury released into your home environment should be treated with caution. While very small spills from items like a broken thermometer might seem insignificant, they still pose a risk. The primary concern is the inhalation of mercury vapor, which can accumulate over time. Even a few beads of mercury can release enough vapor to reach unsafe levels, especially in poorly ventilated areas.
What are the long-term effects of mercury exposure?
Chronic exposure to even low levels of mercury can have serious long-term health consequences. These can include neurological damage (affecting memory, coordination, and mood), kidney problems, and cardiovascular issues. Children and pregnant women are particularly vulnerable, as mercury can interfere with brain development.
Can I use bleach to clean up mercury?
Never mix bleach with mercury. Bleach will not neutralize mercury and may react with it to form even more toxic compounds. Stick to the recommended cleaning methods, such as carefully collecting the mercury beads and using a mercury-binding agent.
What should I do if mercury spills on carpet or upholstery?
Mercury spills on porous surfaces like carpet or upholstery are more difficult to clean. First, follow the steps for collecting visible mercury beads.
