Pest Control

Bed Bugs

Bed bugs are small oval shaped insects. They do not fly; they crawl and attach themselves to surfaces such as clothing, furniture and luggage.  They are attracted to the carbon dioxide that we exhale and can affect anyone at any time. 

Bed bugs are most active at night and are usually found where people sleep. They can also be found in any public space, such as businesses, offices and areas where people gather.

What they look like

  • Bed bugs in all stages of life are visible to the naked eye.
  • Eggs and early stage bugs may be hard to see.  Eggs are the colour white, pear-shaped and about the size of a pinhead.
  • Clusters of 10 to 50 eggs are found on surfaces, cracks and crevices.
  • Adult bugs are about the size and shape of an apple seed. They are 5 mm long, flattened and brown in colour. After feeding they get bigger and turn dark red.

Bed bugs are not known to transmit infectious disease to humans. If bitten, some people may have an allergic reaction that presents as itchy welts. The mental health impacts to people living with bed bugs can include anxiety and insomnia.

These bite marks appear within minutes or days and are usually on the face, neck, upper torso, arms and hands. Not everyone reacts to a bed bug bite.

The following signs can indicate a bed bug bite:

  • Small, raised red itchy welts on your skin, often in a pattern of three.
  • A lump filled with blood or fluid in people with high sensitivity to bed bug saliva.

Most bed bug bites go away on their own and do not need treatment.

  • Keep your skin around the bites clean and wash with antiseptic soap.
  • Avoid scratching bites. If the bites are itchy, you can use over-the-counter antihistamine cream. 
  • Oral antibiotics can be prescribed by your doctor for skin infections.

Bed bugs are most active at night and are usually found where people sleep. They can also be found in any public space, such as businesses, offices and areas where people gather.

  • Use a bright flashlight to look for bed bugs or their dark droppings on bedroom furniture.
  • Use a hot hair dryer and an old business card or playing card to force them out of hiding spaces and cracks.

Bed bug activity can be identified by the following:

  • Finding live or dead bed bugs, or finding bed bug skins in your home.
  • Dark red or brown spots or eggs on mattresses, sheets, bed frames or walls.
  • Flat red marks on your skin, often in a pattern of three. 

Places to look for bed bugs include:

  • Behind headboards.
  • In the seams and tufts of your mattress.
  • Inside of a boxspring.  Remove the dust cover on the bottom of the box spring so you can check inside.
  • Along bedroom baseboard cracks.
  • In and around bedside tables and night stands.
  • Cracks and corners of dresser drawers and other furniture.
  • Telephones, radios, clocks, ceiling light fixtures and smoke detectors.
  • Other bedroom items, including window and door casings, pictures, moldings, nearby furniture, loose wallpaper, cracks in plaster, and clutter.

Tip:Place glue boards, double sided tape or bed bug interceptors under your bed legs to monitor and catch the bed bugs.

It is important to take immediate action if you suspect that you have bed bugs. Bed bugs can spread rapidly so it is important to report these pests as soon as you suspect that they are in your home.

  • If you live in rental housing, report the bed bugs to your landlord as soon as possible. The landlord is responsible for providing pest control services. You are responsible for reporting the pests and helping to prepare your home for pest control treatment. If your landlord does not respond by arranging for pest control services, please call Public Health.
  • If you own your own home, hire a licensed pest control company. Delaying the start of treatment will lead to a more difficult and costly effort to get rid of the bed bugs.

When you have reported bed bugs to your landlord or hired a licensed pest control company, follow their instructions on how to prepare your home for treatment. In addition, you can begin taking the actions recommended below for bed bug removal. 

Removing bed bugs from your home takes time, patience and careful cooperation of the resident, a licensed pest control company.  If you live in rental housing, the landlord will also need to be involved.

Hire a licensed pest control company

Do not try to treat your home with pesticides yourself.  Pesticides available in retail stores are of little effect against bed bugs and will not kill bed bug eggs.  Using these products will cause bed bugs to scatter and spread to other rooms, making it harder to get rid of all the bed bugs.  Pesticides can also be harmful to people and to pets.

  • Never use cockroach spray, ant spray or any pesticide that does not have bed bugs listed on the label.
  • Never spray pesticides on a mattress or sofa.
  • Never spray pesticides in areas where children or pets are present.
  • Do not use an “insecticide bomb” or “fogger” in your home.  These products can spread harmful chemicals throughout the home and are likely to be ineffective against bed bugs.  

Only a licensed pest control professional should handle chemical pesticides. If you live in rental housing, the landlord is responsible for providing pest control services and you are responsible for helping to prepare your home for treatment. 

The pest control company should inspect your home, describe the treatment and tell you how to prepare your home for treatment. Treatment should be done at least two times, 10 to 14 days apart, in order to effectively remove bed bugs and eggs that can survive after the first treatment.  Often, more than two treatments are needed.

Prepare your home before pest control treatment

Review the 3 steps below to help prepare for treatment.

Dispose of unneeded items by placing them into plastic bags, seal tightly, and dispose of the bag in an outdoor garbage container.  Clutter acts as ideal hiding spots for bed bugs and other pests.

  • Be careful not to spread the bed bugs. 
    • Don’t move items from the infested areas to non-infested areas.
    • Don’t donate infested items to someone else. 
  • Throw away excess magazines, newspapers, all cardboard boxes and trash. Put items directly into plastic garbage bags and dispose of them in an outdoor garbage container.
  • Keep all clothing off the floor.

Careful vacuuming is an important step to getting rid of bed bugs and preparing for a pest control treatment.

  • Be sure to vacuum cracks, open spaces and anywhere bed bugs were found during the inspection.
  • Scrub mattress seams with a stiff brush to dislodge bed bugs and their eggs, then vacuum the mattress, box spring, bed frame, bedside furniture, floors and carpets. 
  • If a box spring, couch or upholstered chair has a dust cover attached on the underside, remove it and vacuum inside the space.
  • After vacuuming, carefully empty the vacuum cleaner contents into a plastic bag. Seal it tightly and dispose of the bag in an outdoor garbage container.
  • A regular household laundry dryer can heat clothing and items hot enough to kill bed bugs and their eggs.  Following these steps is critical to kill the bugs and prevent them from spreading:
  • Put all bedding, linens, curtains, rugs and clothing into large plastic bags and seal the bags tight. Bring the laundry to the laundry area in the sealed plastic bags and wash the items.
  • In order to kill bed bugs and eggs, laundry should be placed in the dryer on the hottest setting.  Items need to remain in the dryer on the hottest setting for at least 20 minutes after the items are dry. 
  • Wool items, plush toys, shoes and other items that can’t be washed can be placed dry into a clothes dryer on the hottest setting for 30 minutes to get rid of bed bugs.
  • Put empty plastic bags used to carry the laundry into a garbage bag and seal tightly.  Dispose of them outside.
  • Put clean or heat treated laundry into new, clean plastic bags or sealable containers.  Do not open them until the chemical treatment is finished.

Make your home unfriendly to bed bugs

  • Cover both the mattress box spring in a zippered mattress encasement (a bed bug cover) that is labelled “allergen rated”, “for dust mites” or “for bed bugs”.  Keep the encasement on the mattress and on the box spring for at least one year.
  • Make the bed an island. Bed should be 6 inches (15 cm) away from the wall. Ensure no blankets or bedding touches the floor. This makes it difficult for the bugs to climb into bed with you.
  • Keep clothing off the floor. 
  • Place bed bug interceptors or glue pads under each leg of the bed. 
  • Seal cracks in walls that allow bed bugs to travel between apartments. Seal baseboards, wall switch and plug covers, and where pipes enter the room.
  • Apply weather stripping to the doors into your home.
