Is flea & tick preventative needed all year?

For a lot of people—and their pets!—summer means spending time outdoors. That also means flea and tick preventatives are especially important in the warmer months to keep your pets free of bites and infestations. But what about the rest of the year, when these pests seem to decrease in numbers: is it still important to apply preventatives?

The answer is yes, flea and tick preventatives need to be applied year-round in order to keep your pets safe. Read on to learn more about how fleas and ticks operate, the dangers they can harbor, and how best to protect your dogs and cats.

What You Need to Know About Fleas

Fleas are resilient pests—and because they like a cozy, heated environment whether indoors or out, they’re more than happy to make themselves at home in your home, year-round. They live on dogs and cats to feed on their blood and lay eggs in their fur. (A female flea can lay several hundred to several thousand eggs in her lifetime, so if you catch sight of a single flea, you should know there are way more where that came from.) The eggs fall off of your pet and into the nooks and crannies of your house before hatching.

When dealing with a flea problem, not only does the pet need to be treated but the environment as well. Washing the pet’s bedding in hot water, vacuuming and home ‘bombs’ or foggers are all strategies to help remove and/or kill flea eggs- all of which can be labor-intensive and why prevention is superior to reaction.

Your best bet at preventing a flea infestation is year-round compliance with preventatives. Applications should feel routine, rather than stop-start. Simply set a calendar or phone alert for the same day each month, and take a couple of minutes to prevent a big headache down the line.

Facts About Ticks

Ticks are most active during the warmer months and go into hibernation when it’s very cold out. It is important to note that they’re active during a wide range of temperatures. In fact, many species of ticks go dormant (typically under leaves or other outdoor debris) only when temperatures dip below 35F, or there’s snow on the ground, however, just a short period of warming and they can become active again. Deer ticks are particularly hardy and can become active and look for a food source (your pet!) even after moderate to severe frosts if the daytime temperature warms a bit. Ticks also will not die during the winter months until the temperature falls below 10F for a sustained number of days.

Year-round tick prevention ensures that you and your pet won’t be at the whim of unexpected warm spells or weather patterns. Plus, your pet will be protected during unexpectedly late dormancy periods, and early hatches from an unseasonably warm or early spring.

Why Flea and Tick Prevention Is Important

Remember, fleas and ticks aren’t just pesky irritations—the harm they cause can go far beyond mere itchiness. Ticks can transmit Lyme disease to dogs (amongst other tick-borne illnesses), while skin allergies caused or exacerbated by fleas can lead to sores and infection. Fleas can also transmit an internal parasite, the tapeworm, which can cause malnutrition and weight loss in your pet. Furthermore, the cost of eradicating flea infestations from your home can be quite high.

Finally, don’t forget that flea and tick preventatives for your pet help protect your human family as well. Flea bites can cause skin irritation in humans as well, while Lyme-carrying ticks that are brought in from the outdoors by your pets can easily hop off and attach to the humans in your household.

As the old adage goes, “An ounce of prevention is worth a pound of cure.” Spending a minute or two, once every month, in the application of flea and tick preventatives can save you a lot of time, hassle, pain, and money down the road. So no matter what the temperature, keep up the routine year-round.

Flea Infestation in Dogs

Fleas are parasitic, wingless insects that feed off the blood of their hosts. There are approximately 2,200 types of fleas worldwide, but in North America there are only a few that commonly infect animals: Ctenocephalides felis (the cat flea) and Ctenocephalides canis (the dog flea). Oddly enough, the most common fleas found on dogs are cat fleas, which can cause not only itching and irritation but transmit infection as well.


Lyme Disease in Dogs

Lyme disease, the most common tick-transmitted disease in the world, can affect dogs, most domesticated animals, and humans. The disease is caused by the Borrelia burgdorferi bacteria, which spreads through the bite of several species of ticks.


Should Dogs and Cats Take Heartworm Preventatives

Heartworm disease is a serious, progressive and potentially fatal infection in pets, with few early signs of infection. For dogs, prevention is far superior to heartworm treatment – and for cats, there is no treatment for heartworm. Preventing your pet from becoming infected is better for their health, less expensive, and much less time-consuming than treating heartworm itself.


Dog Skin Allergies: Canine Atopic Dermatitis

Like humans, dogs are susceptible to developing allergies such as atopic dermatitis. If a dog has atopic dermatitis, the immune system reacts too strongly to common environmental allergens that are absorbed through the skin such as mold spores, dust mites, and grass. These irritants become absorbed more easily due to a dysfunction in the skin barrier, which decreases resistance to secondary infections.
