Flea & Tick Information

Fleas and ticks pose a very real threat to the health of your pet and the well-being of your family. FRONTLINE® is the only product of its kind that kills both of these pests on dogs and cats. FRONTLINE is only available from your veterinarian.


Flea infestation is one of the most common health problem in dogs and cats. Almost every dog and cat will become infested with fleas at some time during their life. These tiny, almost-invisible pests are much more than an annoyance. They make life miserable by disrupting your household with a vicious cycle of biting and scratching. The cat flea is by far the most common and is able to live and breed on both dogs and cats as well as to bite humans and other small pets. This means that the cat is often the main culprit of the flea problem when both dogs and cats are living in the same household.

The "flea season": Fleas have become an all-year-round problem which is why your pet should be treated with FRONTLINE all year round. Take a look at the picture below to learn where fleas like to stretch out and settle in:

Flea Life Cycle

Flea Life Cycle

Although adult fleas cause all the clinical problems related to fleas, they represent only 5% of the total flea population. The other 95% consists of immature stages of the flea life cycle which infest the pet's environment (bedding, carpets, furniture etc.). The life cycle of a flea can be up to several months or as little as three weeks, depending upon temperature and humidity.

  • EGG STAGE A female flea lays as many as 50 eggs per day on your pet. The eggs are not sticky, they quickly fall off your pet and hatch in two to five days. A female lays about 1,500 eggs in her lifetime.
  • LARVAL STAGE After hatching, the larvae head away from light toward the dark places around your home and feed on "flea dirt" (dried blood excreted by the flea). The larvae grow, moult twice, then spin cocoons, where they grow to pupae.
  • PUPAL STAGE The length of this stage averages 8 to 9 days. Depending upon weather conditions, population explosions typically occur 5 to 6 weeks after the weather starts to warm up. The pupae are the most resistant life stage within the environment and may remain dormant for up to a year.
  • ADULT STAGE Adult fleas emerge from their cocoons when they detect heat, vibrations and exhaled carbon dioxide indicating that a host is nearby. Once they jump onto a host, the adults mate and begin the life cycle all over again. The entire life cycle can be as short as 3 to 4 weeks.

FRONTLINE breaks the flea life cycle by killing the adults before they can lay their eggs. It then goes on to provide continuous protection against fleas, FRONTLINE Spray for up to 3 months in dogs.

How Fleas Affect Pets

Fleas don't just make your pet itchy, they can actually make him/her quite ill. Be aware of how fleas can irritate your pet! It might be difficult to see fleas, but they certainly can make their presence felt, especially to your pet.

Warning Signs

Be aware of the following warning signs that indicate the existence of fleas on your pet:

  • FLEA DIRT: black specks on your pet or in your pet's bed could be flea dirt, which is dried blood excreted by the adult fleas.

    There are two easy ways to check for 'flea dirt':

    • Flea Comb: available from your veterinary surgeon. Run the comb over your pet, making sure the comb reaches the skin through the coat. If black specks are on the comb when you pull it off, they may be flea dirt. If fleas are on the comb, drown them in a bowl of soapy water before they can get away or jump back on your pet. To distinguish whether a black speck is flea dirt, place the specks on white absorbent paper and dampen. Flea dirt turns red/brown on contact with water.

    • White paper test: place a white paper towel beneath your pet and rub your hands across its fur. If black specks appear on the towel, they may be flea dirt, again dampening will distinguish.

  • AGITATION/SCRATCHING: your pet will become very restless, annoyed and will scratch excessively if infested with fleas.

If either warning sign appears, consult your veterinarian. You can eliminate your pet's existing fleas and prevent them from ever bothering your pet again with regular applications of FRONTLINE.

Flea Related Problems Fleas can affect your pet's health in the following ways:

  • FLEA ALLERGY DERMATITIS (FAD): When a flea bites your pet, it deposits a small amount of saliva in the skin. Your pet can develop an allergic reaction to this saliva (FAD), which causes severe itching. In addition to your pet scratching or biting excessively around the tail, groin or backside, scabs or bumps may also appear on your pet's neck or back.

  • TAPEWORM - Dipylidium canium: Tapeworm eggs are ingested by the flea's larval stages when feeding in the pet's environment. The eggs develop into a dormant life stage within the developing flea. If the flea happens to be ingested by your pet whilst grooming, the tapeworm is released and continues to develop into the adult worm within the intestine of your pet.

  • ANAEMIA: occurs in young, older or ill pets if too many fleas suck their blood. The symptoms of anemia include pale gums, weakness and lethargy in your pet.

You can lower your pet's risk of getting these flea-related problems by regularly applying FRONTLINE to your pet. If you believe that your pet is suffering from any of the above problems, consult your veterinarian.

  • WASHING: wash your pet's bedding, blanket and other washable items frequently in the hottest water possible (check the label to make sure that washing in hot water isn't a problem).
  • ENVIRONMENTAL SPRAYS: a variety of sprays are available aimed at killing the environmental life stages of the flea, ask your veterinary surgeon to recommend one.


Ticks are not insects, but belong to the spider family. Sometimes too tiny to be seen, ticks attach to pets and feed until they are engorged with blood. Ticks cause direct problems for our pets by their presence, local irritation and local infections. Worse still, all life stages of ticks carry diseases that can cause serious health problems both for pets and humans.

Pets are likely pick up ticks in your own garden, in urban parks and from kennels or burrows.

The "Tick Season": In the Philippines, ticks may remain a problem throughout the year on the weather and environmental conditions.

Tick Life Cycle Ticks can live for several years with life cycles between 2 and 6 years. Each developmental stage of a tick's life requires a blood meal in order to reach the next stage.

Ticks lay eggs in secluded areas of dense vegetation that are several inches high. The eggs take about two weeks to hatch. Adult females of some tick species lay about 100 eggs at a time; others lay 3,000 to 6,000 eggs per batch.
After hatching, the larvae move into grass or shrubs in search of their first blood meal. If you or your pet or a small mammal passes by, they attach themselves and crawl upward in pursuit of an area on the skin to feed from.
After this first blood meal, the larvae drop to the ground, moult into their nymph stage. They may remain dormant until the following year before beginning to search for their next host on which to feed. Nymphs are the size of a freckle and often go undetected, increasing the chance for disease transmission.
The engorged nymph drops to the ground and moults to an adult. Again, it may be the following year before the adult searches for a new host. The adult female feeds for 8 to 12 days, possibly increasing its weight 100 times while feeding. While still on the host, the female will mate, fall off and lay her egg mass in a secluded place, beginning the life cycle again.

FRONTLINE is the only product that kills ticks on both dogs and cats in all stages of their development. It goes on to provide continuous protection against ticks with easy, once-a-month applications.

How Ticks Affect Pets

Ticks are second only to mosquitoes throughout the world in transmitting infectious disease to humans and animals. If your pet is bitten by a tick, the results can be fatal. If you have been in areas where ticks are a problem and your dog becomes ill, do not forget to mention to your vet that your pet has recently been exposed to ticks.

Tick Related Problems Tick related problems result from physical attachment of the tick to the skin and the diseases they can transmit to your pet.

Direct effects of ticks attaching to your pet may include:

  • Irritation due to physical presence of the tick
  • Local infection
  • Inflammation
  • Hypersensitivity (allergic) reactions to tick bites

Indirect effect of tick attachment - ticks as the vectors of tick-borne diseases.

  • BABESIOSIS (Babesia canis): In the dog, acute symptoms may include fever, loss of appetite, and general deterioration. Shock, coma or death after less than a day of lethargy and loss of appetite can occur. Responds to a variety of treatments if caught early, although blood transfusion may be necessary in later stages of the disease.
  • EHRLICHIOSIS (Ehrlichia canis): An infectious blood disease that attacks your pet's white blood cells, crippling the immune system. Symptoms include fever, depression, weight loss, loss of appetite and bleeding disorders. Treatable with antibiotics.

Your pet's risk of contracting these diseases can be reduced by regularly applying FRONTLINE to kill ticks. If you believe that your pet is suffering from any of the above conditions, consult your veterinarian.
