Winter might bring cooler temperatures, holiday lights, and cozy nights—but in Florida, it does NOT bring a break from parasites. While pet owners in other parts of the country get a seasonal pause from fleas, ticks, and mosquitoes, our warm climate in Jacksonville means pests stay active 12 months a year.

At Animal Clinic of Mandarin, Dr. Pamela Kaiser and our team want to ensure your dog or cat stays fully protected during the winter months. Here’s what Florida pet parents need to know.

🦟 Florida Winters Are Still Warm Enough for Mosquitoes

Even in December and January, daytime temperatures often sit well above the threshold needed for mosquitoes to survive and reproduce.

Why this matters:

• Mosquitoes spread heartworms, a potentially fatal disease for both dogs and cats.

• Cats can get heartworm disease too—even indoor-only cats.

• A single missed dose of prevention can leave a pet vulnerable to infection.

Heartworm prevention must continue every month of the year to maintain protection.

🐾 Fleas Thrive in Mild Winter Weather

Cooler, damp weather actually creates ideal conditions for fleas to survive outdoors and indoors.

Fleas can:

• Trigger skin allergies and hot spots

• Cause anemia in young or small pets

• Spread tapeworms

• Infest homes quickly, especially during the holidays when guests come and go

Once they get inside, they can reproduce rapidly—making winter infestations surprisingly common.

🌲 Ticks Are Active in Florida All Winter Long

Unlike northern states, Florida doesn’t get temperatures cold enough to reduce tick populations.

Why ticks remain a concern:

• They carry diseases such as Ehrlichia, Lyme disease (less common but possible), and Anaplasma

• Ticks can latch on during outdoor walks, visits to parks, or even a quick potty break

• They hide under leaves, in tall grass, and in shaded backyards—year-round

Consistent tick prevention keeps pets safe from these serious illnesses.

🐶 Why Year-Round Prevention Matters

Stopping preventatives in winter is one of the most common causes of parasite outbreaks.

Pets need uninterrupted protection because:

• Parasites don’t hibernate in Florida

• Prevention works best when kept consistent

• Missing doses creates gaps in coverage

• Some preventatives require several months of use to maintain full effectiveness

If you miss a dose, call us right away so we can advise on how to protect your pet safely.
