What is a Tick?
• Ticks are not insects, they are arachnids (Spiders are also arachnids).
• Ticks are external parasites that live off of the blood of other animals – mostly small mammals, birds, reptiles and amphibians.

Visual sign of Lyme Disease:
This rash may be confused with allergic reactions to tick bites. (However, allergic reactions occur within 24 hours of the bite and they do not spread)
*The rash does not appear on everyone who has been exposed to Lyme disease—it’s only 43-70% of cases.
Bull’s-eye rash
• Expanding rash (bull’s-eye) 3-30 days following tick bite*
• Round, oval, triangular, irregular shaped rash
• Rash is not normally itchy or painful

• Nervous system problems: Bell’s Palsy, numbness, tingling, or pain in the arms and legs

How to avoid Lyme disease…
• Check for ticks every day • Ticks can be very small-- so feel for bumps (especially on the
scalp)• Ticks like certain parts of the body: groin, armpits, around the
waistband, backs of knees, naval, neck and ears (be sure to check those areas)
• When hiking, walk in the middle of the trail• Avoid bushes, grasses, leaf piles, logs and tree trunks• Wear light-colored clothing covering ankles and wrists• Ticks crawl UP, so tuck pants into socks• Consider treating clothing with insect repellent• If you find a tick on you, stay calm and find an adult!

Our Hero: The Western Fence Lizard!
There are proteins in the blood of this lizard that kill the Borrelia burgdoferi bacteria! The proteins in the blood of the lizard are like a neutralizing agent and the bacteria is unable to survive
This means that this lizard could help stop the spread of Lyme disease!

What to do if you get bitten:
• Find an adult immediately to help you!• Using fine point/needle nose tweezers, grasp the
tick as close to the skin as possible (do NOT use wide/square ended tweezers).
• Gently pull the tick straight out, using a firm steady motion.
• Wash your hands and the bite site with soap and water. Apply an antiseptic to the bite site.
• Prompt tick removal can prevent transmission of infection.
• DON’T USE matches/lighters etc.
