The Importance of Proper Tick Removal

If you find a tick attached to your skin, it’s crucial to remove it promptly and correctly. Here’s a step-by-step guide:

1. Use fine-tipped tweezers to grasp the tick as close to the skin’s surface as possible.
2. Pull upward with steady, even pressure. Don’t twist or jerk the tick.
3. After removing the tick, clean the bite area and your hands with rubbing alcohol or soap and water.
4. Dispose of the tick by submersing it in alcohol, placing it in a sealed bag, or flushing it down the toilet.

When to Seek Medical Attention

While not all tick bites lead to illness, it’s important to monitor your health after a tick encounter. Seek medical attention if you experience any of the following symptoms:

• Rash, particularly a bull’s-eye rash around the bite site
• Fever or chills

• Fatigue
• Neck stiffness

Early diagnosis and treatment of tick-borne diseases can prevent serious complications.
