Tick Insect Identification Guide: Reduce Bite & Disease Risks

Identifying Ticks by Sight to Reduce Bite Risks

Ticks are tiny parasitic organisms that feed on the blood of mammals, birds and reptiles. Learning to identify different types of ticks by sight helps you take prompt precautions to avoid bites from these disease-carrying pests. This guide covers tick identification, risks, bite prevention and proper removal.

What Ticks Look Like

Ticks have oval-shaped bodies that become significantly larger when engorged with blood after attaching to hosts. Unfed adults range from about 3-5mm while bloated ticks can swell to 10-20mm wide. Colors vary from pale brown to reddish black. Heres how to identify key tick body parts:

• Capitulum mouthpiece used to pierce skin and feed
• Body fills with host blood as the tick feeds
• Legs used to crawl onto hosts before attaching

Tick Images for Identification

There are over 800 tick species worldwide categorized into hard ticks and soft ticks. Use these tick pictures to help you distinguish common varieties in your region:

Deer Tick

Deer ticks have reddish-brown bodies with black legs and grow to about 3-5mm unfed. Also called blacklegged ticks, they can transmit Lyme disease, anaplasmosis, babesiosis, ehrlichiosis and other harmful infections.

Lone Star Tick

Named for white dot markings on female adults, lone star tick bites may cause a red meat allergy. They are aggressive biters that can also spread ehrlichiosis, tularemia, Heartland virus and southern tick-associated rash illness (STARI).

Dog Tick

Wood ticks or dog ticks have whitish bodies with brown or black markings. Unfed adults reach about 3mm long but swell dramatically larger when engorged. Diseases spread through their bites include Rocky Mountain spotted fever and tularemia.

Brown Dog Tick

Brown dog ticks feed on dogs but sometimes bite humans. Ranging from brown to gray with mottled skin, they grow up to 11mm when engorged and are vectors for spotted fever group rickettsia and ehrlichia canis. Pets carry them indoors.

Dangers of Tick Bites and Disease Transmission

While all tick bites can cause redness, pain and itching, some species transmit harmful pathogens through saliva as they latch onto hosts and feed. Diseases spread via tick bites include:

Lyme Disease

Blacklegged deer ticks spread Lyme disease, which causes fever, headaches, fatigue and skin rash in early stages. Without treatment, the infection can progress to facial paralysis, severe joint pain, heart palpitations and neurological disorders.

Anaplasmosis

Deer tick-induced anaplasmosis leads to similar flu-like symptoms along with dangerously low white blood cell and platelet counts. Life-threatening complications include internal bleeding disorders and respiratory failure.

Ehrlichiosis

Bacteria causing ehrlichiosis enter white blood cells, multiplying rapidly to cause an infection with high fever, muscle pains, nausea and confusion. breathing issues, bleeding disorders and organ damage may develop without prompt treatment..

Rocky Mountain Spotted Fever (RMSF)

Despite its name, RMSF transmitted via wood ticks and dog ticks primarily occurs in the southeastern U.S. Sudden high fever, headache, nausea and rash erupt followed by dangerous systemic disorders if untreated.

Alpha-gal Meat Allergy

Lone star tick bites can trigger alpha-gal meat allergy, causing hives, stomach cramps, wheezing or anaphylaxis hours after consuming red meats. The delayed reaction complicates diagnosis. Reactions worsen with repeated tick bites.

How to Check for and Remove Ticks

Promptly finding and properly removing attached disease-carrying ticks reduces infection risks. Heres how to check yourself, family members and pets after possible exposure:

Tick Bite Inspection Steps

1. Check clothing after being outdoors
2. Conduct full body exam of skin folds, behind ears, armpits
3. Carefully part hair to inspect the scalp
4. Ask family to check your back if necessary
5. Repeat tick checks daily when exposure risk runs high

Safe Tick Removal Process

If you find an attached, embedded tick, follow these steps:

1. Use thin tweezers to grasp tick close to skin surface
2. Pull straight up slowly and firmly until it releases
3. Clean bite site and hands thoroughly with rubbing alcohol and soap
4. Save tick in a sealed container to aid identification
5. Watch for rash or symptoms and notify your doctor about the bite

Avoid These Tick Removal Methods

Do NOT:

• Twist or jerk the tick
• Apply substances like petroleum jelly, alcohol or detergents
• Burn tick with heat from matches or cigarettes
• Crush or puncture its body if possible

These methods may release more pathogens into the bite and leave detached tick mouth parts embedded in your skin.

Reducing Risks From Tick Bites and Diseases

Protect yourself and loved ones from tick-borne illnesses by taking these proactive precautions:

Avoid Tick Habitats

Ticks live in damp, overgrown brush and tall grass waiting to latch onto passing hosts. When possible, avoid wooded areas with heavy undergrowth and keep lawns trimmed short.

Use Repellent and Protective Clothing

EPA-registered insect repellents containing DEET, picaridin or other approved ingredients effectively deter tick bites when applied to exposed skin and clothing per label instructions.

Treat Clothing and Gear

Spray outerwear and camping equipment with Permethrin repellent for extra protection. It binds tightly to fabrics even through repeated washings.

Check for Ticks After Outdoor Activity

Carefully inspect all body parts and remove any attached, embedded ticks promptly using proper technique to lower disease risks.

Shower and Wash Clothes

Shower soon after coming indoors to wash off unattached ticks. Toss exposed clothes in the dryer on high for 30 minutes kill any remaining ticks.

What To Do If a Tick Bite Occurs

Even with precautions, tick exposure still occurs on occasion. If you or family members experience a tick bite, take these steps:

• Save the removed tick in alcohol for species identification
• Record date and location of the bite for reference
• Watch closely for rashes, flu symptoms or high fever in the weeks following
• Contact your healthcare provider for blood tests and possible antibiotics

Early Lyme disease and other tick-related infections often resolve without complications when diagnosed promptly. But delays may allow serious manifestations to develop.

Signs of Tick-Borne Illness

Contact your doctor immediately about previous tick bites if you notice:

• Expanding bullseye rash at bite site
• Severe headache, neck stiffness or sudden high fever
• Unexplained joint and muscle aches
• Heart palpitations or dizziness
• Facial paralysis or slurred speech

Starting appropriate antibiotics quickly provides the best chance of preventing progression to advanced Lyme disease, anaplasmosis, ehrlichiosis, Rocky Mountain spotted fever or other dangerous tick-transmitted infections.

Using Pest Control Help to Reduce Ticks

In areas with heavy, endemic tick infestations, professional pest control treatments can suppress population numbers on residential properties through:

• Treating vegetation and yard perimeters with acaricides
• Applying bait boxes targeting rodents that serve as hosts
• Introducing predator mites that attack ticks
• Releasing sterile male ticks to disrupt breeding

Consult reputable pest management companies familiar with regional tick control challenges for long term reduction of species capable of transmitting infections through bites.

Stay Vigilant Against Tick Bites

Learning to identify common disease-carrying ticks by sight helps you take appropriate precautions. Avoid tick habitats when feasible, use repellent and protective clothing and promptly remove attached ticks to reduce likelihood of contracting debilitating Lyme disease, anaplasmosis, ehrlichiosis and other increasingly prevalent tick-borne illnesses.
