Fentanyl Decontamination Frequently Asked Questions in San Mateo, CA

Why can't I just vacuum or sweep?

Fine powder can rise into the air when it is swept, wiped dry or vacuumed with an ordinary vacuum. Cleanup teams use wet methods and controlled equipment so particles stay down. Agencies such as the CDC advise against disturbing powder.

Do I need to be at the property?

Often not. In many cases the person who calls does not need to be on site. The team may need access, keys and a point of contact. Ask how that can be arranged, especially if you are out of town or the space is vacant.

What is fentanyl decontamination?

It is the careful removal and cleaning of fentanyl powder or residue from a home, vehicle or workplace. Cleanup crews wear protective gear, control the air, collect residue without raising dust, clean surfaces and seal waste. A record of the work is usually available at the end of the job.

Can residue be on clothing or belongings?

It can. Clothing, bedding, bags and furniture in an affected space may carry powder. Do not shake them out. A team can advise on what to bag, clean or discard.

Will the cleanup be private?

Many teams can arrive in an unmarked vehicle and work quietly. If privacy matters, ask about it when you call. The crew asks only what it needs to plan the work, and you decide what else to share.

Can I clean fentanyl residue myself?

It is not recommended. Sweeping, wiping and vacuuming can lift fine powder into the air. Leave the area, keep people and pets out, and call 911 in an emergency or Poison Control with questions. Then ask a cleanup team about decontamination.
