Have your pets got fleas?

Fleas are the most common parasite in dogs and cats and every dog and cat is likely to be infected at some stage in its life. However, with the advent of modern products it is possible to prevent fleas from becoming a problem in your household. Working closely with your vet, who will give you advice on how to use these products effectively, you will be able to stop these nasty little insects making a meal of your pet and you!

Why is it so difficult to get rid of fleas?

Fleas are small, reddish-brown insects who lead a complex life away from your pet. Only the adult fleas live on your pet and drink its blood; the early stages live free in the environment, ie your home. For every flea that you see running through your pet’s fur, there may be hundreds of young fleas waiting to jump aboard a passing pet – or if you are unlucky – onto you.

Eggs 0.5 mm diameter, white, glistening and not sticky.

Where do fleas live?

Adult fleas lay eggs in the pet’s fur. Each female flea can produce dozens of eggs every day. They are pearly white in colour and about the size of a grain of salt. The eggs do not stick to the fur and soon fall off onto the floor.

After a few days, the eggs hatch into maggot-like larvae which hide in your carpets, cracks in the floor, under the house or in your pet’s bedding. They feed on dust and the droppings of adult fleas, which mostly consists of undigested blood.

After a time, the larva spins a cocoon in which it develops into an adult flea. They may stay in this resting stage for several months but finally the adult flea breaks out of its cocoon and crawls out of its hiding place to look for food. If it cannot find a dog or cat it will hop on to any warm-blooded animal that passes by, including humans. Hot summer weather and centrally heated homes provide ideal conditions for a flea to grow rapidly from an egg into an adult. The minimum time for the cycle is two and a half to three weeks, but young fleas can live for over a year before reaching maturity and getting back on your pet. Most adult fleas live for 2-3 months feeding – the females feed on blood from biting your pet.

How do fleas damage my pet’s health?

Fleas are the most common cause of skin disease in cats and dogs. Flea spit contains chemicals which stop blood clotting until the flea has finished feeding and these chemicals may cause an allergic reaction in your pet. Most animals are not affected by this allergy, but those which are suffer severe itching. Affected animals lick or rub themselves, wearing away their fur and making their skin red and sore. Sometimes a crusty rash will develop. Allergies appear most often in summer when the flea population is greatest. Skin problems may continue long after the flea which caused it has gone but they should eventually disappear if you treat your pet to remove fleas and continue treatment to stop the fleas returning. In the short term your vet may prescribe drugs to stop the itchiness.

Do fleas just cause skin problems?

Immature fleas pick up infection from the environment and may carry the eggs of an immature form of tapeworms. If the flea is accidentally swallowed by an animal whilst grooming, the tapeworm can develop inside the dog or cat’s gut. Once inside your pet, the tapeworm continues to grow and may reach as much as 60 cm long. If you have seen fleas on your pet you should treat your pet with a product to remove tapeworms as well as getting on top of flea control. We recommend Drontal, Endogard, Milbemax or Profender to kill all worms including tapeworms.

How can I tell if my pet has fleas?

  • Take a sheet of good quality white paper and wet one side by running it under the tap.
  • Place the sheet on a flat surface, eg worktop, with the wet surface uppermost.
  • Sit your dog against the edge of the paper.
  • Rub or brush the small of your pet’s back so that scurf and flea droppings fall onto the wet paper.
  • Look for ‘coal dust’ which, after 30-60 seconds, goes reddish brown. (This is the dried blood in the flea droppings.)

Sometimes there are no obvious signs of fleas and your vet might suggest testing your pet’s skin to see if it is allergic to flea spit.

How can I get rid of fleas?

The secret of successful flea control is to treat both your pet and its environment with effective products which kill the adult and the immature fleas. There is a range of tablets, powders, sprays and shampoos to destroy the fleas in your pet’s fur. Not all products are equally effective and those you can get from your veterinary surgeon are usually much better than those sold in pet shops or supermarkets.

As you can see, these products have different benefits. We like them all for different reasons.

What is environmental flea control?

Treating the areas where your pet spends most of its time is also important – particularly the places it lies down to sleep. Washing your pet’s bedding in hot water will destroy the young fleas (but not the eggs) and vacuuming your carpets also helps keep the numbers down. Some products kill the flea itself and some prevent immature fleas from developing and reinfecting your pet in the future. Your vet can advise you on which product, or combination of products, to use. See above list of treatments for details. All the products we recommend prevent egg-laying by killing almost 100% of fleas before they have a chance to lay eggs. Most of the products also kill larvae in the environment by contact with the product in the ‘dander’ that is shed from your pet. Frontline Plus additionally prevents immature fleas from developing into adults. If the environmental flea burden is high and you want to ‘flea bomb’ your house, we recommend using the Indorex House Pack.

You must continue to treat your pet and your home all year round, even if you do not see fleas.

What if I have other pets?

All the cats and dogs (because most fleas on dogs are cat fleas), in a household should be treated even if only one animal appears to be affected by flea bites. If you do not continue treatment, the affected animal may be reinfected with fleas carried by other animals in your home or by fleas it picks up outside.

Conclusion

Fleas can be a real menace, particularly if you have more than one pet. Regular treatment with the products recommended by your vet should keep fleas under control all year round. Use your diary or calendar to note down when the next flea treatment is due – do not rely on your memory.
