Fleas and ticks thrive in warm weather, which, in many states, starts around springtime. Once temperatures drop, usually below 45 degrees Fahrenheit, these parasites become less active and less of a threat.
Yet, many environmental factors can influence the intensity of fleas and ticks from year to year. As the climate is warming and seasons shift, these parasites are appearing even earlier than many dog owners had initially anticipated.
Regardless of the climate where you live, it鈥檚 important to learn when your pets are most at risk. Whether flea-or-tick season has started in your state or otherwise, you can keep your dog safe with some preventative measures.
Fleas and Ticks: Nuisances That Carry Disease
While there are key differences, fleas and ticks are both parasites that suck blood from both animals and people. A host serves two purposes: a consistent food source and a temporary home. However, this is not a symbiotic relationship; both can transmit life-threatening diseases if not promptly removed from the host.
There are at least 90 species of ticks in the U.S. One of the deadliest varieties is the black-legged tick, also known as the 鈥渄eer tick.鈥� In some parts of the country, up to 15% of these arachnids can transmit Lyme disease, which can lead to cardiac, neurological, and urinary complications in dogs.
notes that there are over 300 species of fleas in the U.S. Fleas cause more than itching and skin irritation; some carry tapeworm eggs, which can be transmitted to dogs when they groom themselves and ingest the insects.

Fleas Thrive in Mild Temperatures
Fleas thrive in humid areas, typically found among tall grasses and shrubs. However, in the wild (and without a consistent food source), a flea will die within one to two weeks 鈥� a fraction of its 100-day lifespan. That鈥檚 why these six-legged hoppers jump from dog to dog, and a flea can jump a distance of nearly 100 to 200 times its own size.
A flea鈥檚 lifecycle also plays a critical role in when they become more of a threat to dogs. They have four life stages: egg, larvae, pupa, and adult. When environmental conditions aren鈥檛 ideal, such as temperatures dipping below 45 degrees Fahrenheit, the pupa can stay in their cocoons and bide their time until temperatures increase.
While fleas don鈥檛 live in colonies, female fleas can start laying eggs almost immediately after first feeding on a host. They can lay about 50 eggs per day, meaning it鈥檚 not long before one flea on your dog could turn into several.
Ticks Can Survive Long Periods Without Hosts
Ticks can survive months without feeding on a host鈥檚 blood. They鈥檙e typically found in wooded areas littered with dead leaves, or wood piles, especially in moist areas or near bodies of water. They鈥檙e also common after periods of heavy rainfall. During the winter, they burrow for insulation, where they enter a period of low energy. Then, around springtime or any days when the weather gets warmer, they exit their dormant period and look for hosts.
Nature relies on frigid winters to cull the tick population 鈥� at least to some extent. A study conducted by the found that tick populations start decreasing when temperatures dip to -2 to 14 degrees Fahrenheit.
During especially colder seasons, up to 20% of a local tick population could die off. As records indicate warmer and warmer years, ticks also come out sooner. Since not as many ticks were culled during the winter, there could be more once temperature conditions are ideal for them to thrive.
Fleas on Your Dog: What to Know
Nobody wants to discover fleas on their dog. However, these insects are sneaky and can be difficult to spot. If you notice your dog persistently itching, you鈥檒l need to do some investigating to confirm whether they have fleas. Some signs include:
- Fur loss
- Flaky skin
- Scabs
- Raised, red bumps
- Biting and chewing at the skin
- The insects crawling on the dog鈥檚 fur (particularly on its neck and shoulder blades)
- Flea dirt
You鈥檇 find 鈥渇lea dirt鈥� on your dog鈥檚 belly and underside, and where the fur thins around their joints. Flea dirt is a flea鈥檚 excrement, which contains a dog鈥檚 digested blood. It appears as small, black, and flaky, and is commonly mistaken for regular dirt, or fleas themselves. Since flea dirt is feces left behind by these parasites, it generally only arises after the flea has fed on the dog鈥檚 blood.
The good news is that there are many medications that kill fleas, including or . There are also preventative vaccines your vet can administer before flea-and-tick season starts.
Ticks on Your Dog: Important Considerations
No matter where you live, you should regularly examine your dog for ticks after long periods of being outdoors. But there鈥檚 no need to panic if you find one or several. If caught early, you can comb the tick out of your dog鈥檚 fur, but be sure to . You don鈥檛 want it finding its way back to your dog 鈥� or you.
If you find a tick that has attached itself to your dog, there鈥檚 usually no need to worry. To safely remove the tick:
- Part your dog鈥檚 fur with a to zero in on the tick.
- Grasp the tick鈥檚 head with , getting as close to the skin as possible.
- Gently pull in a straight, outward motion.
- Dispose of the tick.
- Pat the tick bite with a disinfectant using a simple saline solution.
Over the next few days, monitor the bite for signs of irritation, redness, and swelling. Your dog will typically return to its normal activities in a few days鈥� time.
Preventing Fleas and Ticks Is a Year-Round Practice
Flea-and-tick season varies from year to year, with geographic location, weather conditions, and temperature being key contributors. But, regardless of where you live, prevention is key to keeping your dog from contracting flea-and-tick-borne diseases. By consulting your dog鈥檚 veterinarian, you can implement a well-rounded treatment plan that considers your pet鈥檚 age, immune system鈥檚 strength, and activity level.
