Lyme disease is caused by bacteria that is spread through the bite of an infected blacklegged tick, also known as a deer tick. The Government of Ontario provides more information on Lyme disease and how to identify a blacklegged tick.
What to do if you are bitten by a tick
Remove a tick as soon as possible to reduce your risk of getting Lyme Disease.
- using fine-tipped tweezers, carefully grab the tick close to the skin
- pull it straight out, gently but firmly
- don't squeeze the tick!
- don't put anything on the tick or try to burn it off
- clean the bite site with rubbing alcohol and or soap and water
Ticks that have been removed from a person can be brought to Southwestern Public Health for identification. Knowing the type of tick, can help determine the risk of getting Lyme disease.
- place the tick in a screw-top bottle or hard plastic container
- keep an eye out for symptoms such as fever, chills, headache and/or the bull's eye rash (not everyone develops the rash)
- talk to your health care provider if you have any concerns
- ticks will be identified but there is no testing for Lyme disease in the tick. Your health care provider will assess your risk of Lyme Disease based on how long the tick was attached, symptoms and other factors.
Note: Southwestern Public Health staff are not able to remove ticks from clients.

- Tuck your pants into your socks
- Wear light-coloured clothing to spot ticks easier
- Use a bug spray with DEET as directed on the label
- Do a tick check after walking in an area where ticks might be
- Shower and towel off to remove any ticks that might not be attached, and then check underarms, neck and groin area
- Learn more about Tick Bite Management
