Lyme disease is a serious illness caused by bacteria that are spread through the bite of an infected blacklegged tick (also known as a deer tick). If you think you have been bitten by a tick and are concerned, contact your healthcare provider. If possible, keep the tick and complete the Tick/Insect Submission form (PDF, 1 page, 290 KB) to submit it to Public Health for identification.
Ticks are usually found in woody or bushy areas but because they can be carried by birds it is possible to encounter them just about anywhere. Ticks do not jump, fly or move very quickly, but will wait on low-growing vegetation and easily latch onto people and pets that brush against them.
A tick must be actively feeding to spread bacteria, including the bacteria that cause Lyme disease. Lyme disease may be prevented through the use of antibiotics if detected soon enough. Contact your healthcare provider if you are concerned.

What to do if you’ve been bitten by a tick
If you’ve been bitten by a tick, remove it carefully using tweezers following these instructions or a tick remover.
- Flick or scratch an attached tick
- Use petroleum jelly, heat or nail polish to remove a tick (these take too long to work)
- Remove a tick while holding it around the middle (abdomen)
- Burn an attached tick
These methods increase the chance of forcing harmful microorganisms out of the tick and into your bloodstream.
Submit the tick to Public Health for identification.
How to submit a tick for identification
Public Health will identify ticks that were found on humans, pets and other animals. Only blacklegged ticks involved in human exposures, and from within the borders of Wellington-Dufferin-Guelph Public Health, will be forwarded to Health Canada to be tested for the bacteria that cause Lyme disease.
- Keep the tick:
- Put live tick in a clear container that has a tight-fitting screw-top lid and add a small amount of rubbing alcohol, OR
- Put ticks/insects into a freezer for at least 12 hours prior to submitting.
- Print and fill out the Tick/Insect Submission Form (PDF).
- Submit the tick and form to us for identification by calling 1-800-265-7293 ext. 4753 or by bringing it into one of our offices.
