Fleas and Ticks Beyond Summer

Summer is winding down, and soon we’ll be able to enjoy cooler autumn weather. Along with the cooler weather comes the misconception that our pets no longer need their monthly flea and tick prevention.

Although it’s true that a lot of tick species are most active in the summer, there are some species of ticks that remain active in the fall in Illinois. Likewise, flea season in Illinois can last well into the winter. In fact, flea and tick infestations are most frequently encountered in September through November. Without the protection of monthly prevention, fleas and ticks can cause a variety of health issues for our pets.

Fleas

Our pets can get fleas from just about anywhere, including from other animals, outdoors, and even an indoor environment if the fleas hitch a ride from the outside on shoes. Fleas can cause itching and discomfort, and if your pet is allergic to fleas, they can develop flea allergy dermatitis. Flea allergy dermatitis causes intense itching, severe discomfort, hair loss, and secondary skin infections. In severe flea infestations, our pets can develop anemia secondary to blood loss from the fleas feeding. Finally, fleas also put our pets at risk for intestinal parasites called tapeworms, and Bartonella, a bacterial infection that may cause severe disease and require up to 6 weeks of treatment.

Ticks

Ticks can attach during walks, hikes, or any outdoor activity. This is especially true in wooded areas or places with tall grasses. Ticks can carry Lyme Disease, Rocky Mountain Spotted Fever, Anaplasmosis, and Babesiosis along with other bacterial and protozoal diseases. A variety of clinical signs can develop from these diseases, including swollen joints and lymph nodes, fever, lethargy, loss of appetite, diarrhea and vomiting. In severe cases, pets can develop heart and liver disease and kidney failure.

In addition to the health issues fleas and ticks cause for our pets, they can also infest your household. Clearing your household of these infestations can be labor-intensive, costly, and may take weeks to months to be fully effective.

So, as we approach the cooler months, keep your pets healthy and safe and resist the urge to skip that next monthly dose of their flea and tick prevention.
