For example, performing a tick check on a dog with thick curly hair, or keeping an outdoor cat away from long grass is not always realistic!
Keep in mind the Lyme disease vaccine does not protect against other emerging tick-borne diseases, so tick prevention methods will still be important.
The number of reported cases of anaplasmosis in Canada has been increasing in the last few years. The bacteria causing anaplasmosis in humans, dogs and cats is different to the one causing disease in cattle.
Acaricides are substances which are harmful to ticks, just as insecticides are harmful to insects.
Key areas to check in infants and young children are the head, hair and ears.
The act of hunting can mean individuals are spending more time in tick habitats. Furthermore, deer are important hosts for the blacklegged tick, and visiting areas where deer are abundant may increase exposure to ticks. While deer play an important role in the life cycle of ticks, they do not get infected with Lyme disease. Therefore, people cannot be infected with Lyme disease by eating meat from deer.
Ticks prefer habitats which are damp. They generally do not survive in habitats which are hot and dry.
Depending on where you live and your specific concern, you may be able to receive assistance by contacting your provincial health telephone line, local physician, nurse, pharmacist, veterinarian or hospital emergency room.
The tick pierces the skin and embeds itself using barbed mouthparts. Rapidly pulling out the tick may lead to the barbed mouthparts being retained in the skin. The following photos show the barbed mouthparts in two different species of tick.

It is possible that pets can bring ticks into the home, however ticks will usually prefer to stay on an animal than to move onto a human. Once a tick has fed on a pet, it will detach and look for a place where it can transform to another life stage or lay eggs. If a tick falls on the ground in your home, it will most probably die, as the environment is too dry and unfavourable for them. It is very unlikely that it will bite another person or pet after that.
Ticks are usually active above 4°C/30°F. Depending on where you live, ticks may be seasonal (e.g., from April or November), or they may be active all year. You can know when ticks have been found in your region by checking the real-time map on eTick.
The behaviour ticks use to attach to an animal or host is called questing. Using their back legs to hold onto tall foliage or grass, they stretch out their front legs, waiting to climb onto a passing host.

In general, ticks are active when the temperature is above 4°C (39°F). However, be aware that local microclimates in tick habitats can mean that ticks are active while ambient temperatures are less than 4°C.
Permethrin-treated clothing offers protection against ticks and mosquitos. This clothing has been used by the military for several decades and is approved for individuals over the age of 16 years. Permethrin-treated clothing is suitable for women who are pregnant or nursing, however it is recommended that women do not wear the clothing while nursing to avoid putting infants in contact with the product. For more information on how to use permethrin-treated clothing, consult this Public Health Agency of Canada webpage.

It can be helpful to have a full-length mirror, a handheld mirror, and lint roller where you will be conducting the checks. Identifying a tick can be made easier with a magnifying glass, or taking a digital photo and zooming in.
Nymphs can be mistaken for moles or freckles as they are so small
10 minutes: It will need to be longer if clothes are wet.
How frequently you perform a tick-check depends on your comfort level and type of activity. If you are working outdoors all day, you may choose to perform a brief tick check at each break and a thorough tick check at the end of the day. If you are going on a short hike, you may choose to perform one thorough tick check when you return home. Of course, you can also keep an eye out for ticks throughout the activity.
