First 48 Hours: Containment Actions To Stop The Spread

You have confirmed evidence of bed bugs — or strong enough suspicion to act. The next 48 hours are about containment: reducing your exposure, preventing the bugs from spreading to other rooms, and preparing the space for professional assessment. Every action in this section can be done without chemicals and without professional help.

What To Do Immediately

1. Keep sleeping in the same room. This is counterintuitive, but it is critical. Health Canada specifically warns against moving to another bedroom. Bed bugs follow their host. If you relocate, surviving bugs will follow — or you will carry hitchhikers on your clothing and bedding — and start a new infestation in a previously clean room. Instead, make the bed safer.

2. Make your bed an island. This is the core containment tactic, and Ottawa Public Health outlines it clearly:

• Pull the bed away from the wall — at least 15 cm on all sides
• Remove and bag all bedding, pillows, and bed skirts
• Ensure no blankets, sheets, or clothing drape to the floor
• Vacuum the mattress, box spring, and bed frame thoroughly
• If you have bed leg interceptors (small cups that trap climbing insects), place them under each leg now — they are inexpensive and available at most hardware stores
• As a temporary measure, coat bed legs with petroleum jelly or wrap them tightly with double-sided tape to prevent climbing

3. Heat-launder everything from the bed. Strip all linens, pillowcases, mattress protectors, and any clothing stored near the bed. Wash in hot water with detergent and dry on the highest heat setting for at least 30 minutes. Bed bugs die at temperatures above 50°C, and a standard household dryer on high comfortably exceeds that. Items that cannot be washed can go in the dryer alone on high heat for 30 minutes. Bag treated items in clean, sealed bags until the infestation is resolved.

4. Vacuum methodically. Use a vacuum with a crevice tool — a HEPA filter model is ideal. Vacuum all sides of the mattress, box spring, bed frame, headboard, baseboards, and any nearby upholstered furniture. After vacuuming:

• Immediately seal the vacuum bag in a plastic bag and dispose of it in an outdoor bin
• If using a bagless vacuum, empty the canister into a sealed bag, then wash the canister and attachments in hot, soapy water
• Do not use a vacuum with a cloth bag or fabric hose — bed bugs can live inside them and re-infest the area

5. Reduce clutter around the bed. The fewer hiding spots available, the fewer places bed bugs can harbour between feedings. Remove stacked books, magazines, clothing piles, and storage boxes from the floor near the bed. Bag items you are not using and seal them.

What NOT To Do

These are common instincts that backfire:

• Do not move furniture between rooms. You risk carrying bugs to clean areas.
• Do not throw out your mattress — yet. In many cases, encasement and treatment can save it. If you do discard furniture, Health Canada advises wrapping it completely in plastic, taping edges closed, and clearly labelling it as bed-bug infested. Leaving uncovered infested items at the curb or in a hallway spreads the problem.
• Do not apply pesticides yourself without reading the label. Only products with a Canadian Pest Control Products (PCP) registration number are legal for use in Canada. Never apply pesticides to skin, pets, cribs, playpens, or to mattresses unless the label specifically permits it. Health Canada warns that homemade pesticide mixtures and ozone generators are unsafe and potentially illegal.
• Do not assume a single cleaning will solve the problem. Containment buys time. It does not eliminate an established infestation.
