Understanding Flea Season in Marquette, MI

As temperatures rise in the Upper Peninsula, flea populations also increase—posing a risk to pets throughout the Marquette area. Even during cooler months, fleas can survive in warm indoor environments, making year-round protection essential.

One of the most common and uncomfortable conditions we see related to fleas is Flea Allergy Dermatitis (FAD). This blog explains what FAD is, how to recognize the signs, and—most importantly—how to prevent and treat it effectively.

If your pet is scratching more than usual, don’t wait: request an appointment with our veterinary team.

What Is Flea Allergy Dermatitis (FAD)?

Flea Allergy Dermatitis is an allergic reaction caused by flea saliva—not the flea itself. When even a single flea bites a sensitive pet, it can trigger a cascade of uncomfortable symptoms.

Common Signs of FAD:

  • Persistent itching, often near the base of the tail
  • Red, inflamed skin
  • Hair loss or thinning fur
  • Scabbing or crusty sores
  • Secondary skin infections from excessive scratching or biting

Pets with a history of flea exposure or sensitive skin are more prone to developing FAD, but it can affect any dog or cat.

Understanding the Flea Lifecycle

Effective flea control starts with understanding how fleas live and reproduce. According to the Centers for Disease Control and Prevention, the flea lifecycle includes four stages:
Egg → Larva → Pupa → Adult

While adult fleas live on pets, the eggs, larvae, and pupae are typically found in carpets, bedding, and outdoor environments. Fleas can persist in your home or yard for weeks or months—making it crucial to treat both the pet and their environment to break the lifecycle.

Even indoor-only pets are at risk, as fleas can hitch a ride into homes on shoes, clothing, or other animals.

Diagnosing Flea Allergy Dermatitis

When you bring your pet to the Animal Medical Center of Marquette, our team will conduct a thorough examination to determine the cause of your pet’s itching.

Diagnostic Process:

  • Physical exam: Assess skin, coat condition, and flea debris
  • Flea combing: Look for adult fleas or flea dirt
  • Skin or blood testing: Rule out other skin conditions like atopic dermatitis or food allergies

Professional diagnosis is key to effective treatment. Over-the-counter treatments often miss the root cause and can delay relief.

Treatment of Flea Allergy Dermatitis

Addressing FAD involves a three-step approach:

1. Eliminate Fleas on Your Pet

  • Fast-acting oral or topical flea treatments
  • Anti-itch medications to reduce inflammation
  • Antibiotics if secondary skin infections are present

2. Treat the Environment

  • Frequent vacuuming of floors and upholstery
  • Wash pet bedding and soft surfaces regularly
  • Consider professional pest control for severe infestations

3. Ongoing Prevention

  • Maintain consistent flea prevention year-round

Flea and Tick Prevention Options

Preventing fleas is not only easier than treating an infestation—it’s also more cost-effective in the long run.

At the Animal Medical Center of Marquette, we commonly recommend:

  • Monthly topicals and/or oral preventatives for both dogs and cats
  • Veterinarian-approved flea collars with long-lasting protection
  • Livestock-specific strategies for barn animals or multi-species households

It’s important to select the right product based on your pet’s species, weight, age, and any underlying health conditions.

Tips for Year-Round Flea Control in Marquette, MI

Despite the colder climate, fleas can remain active indoors throughout the year.

Best Practices:

  • Apply preventatives every month, regardless of season
  • Monitor both indoor and outdoor pets regularly for signs of fleas
  • Maintain clean living spaces and reduce wildlife access around your home or barn

Fleas thrive in homes, barns, and even wooded areas—so staying proactive is key.

When to See a Veterinarian

If you notice any of the following signs, your pet may be suffering from FAD:

  • Persistent scratching or biting
  • Bald spots or thinning fur
