Tick time is here, warns Interior Health

NEWS — It’s tick season. Those small bugs that feed on the blood of humans and animals and can sometimes transmit disease appear as the weather changes.

“Ticks are most often found in tall grass and wooded areas so covering up before you head outdoors and checking for ticks on yourself, your children and your pets after being outdoors are simple things that go a long way to prevent tick bites,” said Jennifer Jeyes, communicable disease specialist with the Interior Health Authority.

The most common tick species in the Interior Health region is the wood tick (Dermacentor andersoni), which does not carry the Lyme disease bacteria.

The wood tick can carry other diseases such as Rocky Mountain spotted fever, although it’s rare.

Jeyes said some ticks also have toxins that can cause temporary muscle weakness and paralysis if attached for several days, but the symptoms fade once the tick is removed. Signs of many tick-borne infections can be quite similar and include fever, headache, muscle pain and rash, she said.

The tick species that carries Lyme disease (Ixodes pacificus) is more common in the coastal areas of B.C. but may also be present in low numbers in the Interior region. Less than one per cent of Ixodes ticks in B.C. carry Lyme disease.

In addition to fever, headache, and muscle pain, people infected with Lyme disease will often develop a rash that looks like bull’s-eye target and expands from the site of the tick bite.

“Most tick bites do not result in illness. However, all tick bites should be cleaned, as infection can occur whenever there is a break in the skin,” said Jeyes.

“It is important to watch for signs of tick-transmitted illnesses. Anyone who experiences a bull’s-eye rash or other symptoms should see a doctor as soon as possible.”

Other precautions include:

• Walking on cleared trails when in tall grass or wooded areas.
• Wearing a hat, long sleeves, pants, and light-coloured clothing.
• Tucking pant legs into socks or boots.
• Applying insect repellent containing DEET on uncovered skin.
• Carefully checking clothing and scalp (covered or not) when leaving an area where ticks may live.
• Having a shower after returning from areas where ticks may live.

To reduce ticks entering your home and yard, IHA recommends:

• Keep your lawn short and remove any fallen leaves and weeds.
• Keep a buffer areas such as wood-chip or gravel border between your lawn and wooded areas.
• Trim tree branches to allow more sunlight in your yard.
• Keep wood piles and bird feeders away from the house.
• Widen and maintain trails on your property.
