What to Do When You See a Flea

Fleas are one of the most common causes of itchiness in our furry family members. The good news is, this article will give you everything you need to deal with them!  

What are fleas? 

 Fleas are small little jumping insects that sit on your pet’s skin and feed on their blood.   

Why are fleas a problem? 

 Don’t worry – they don’t suck enough blood to become life threatening. But they are a nuisance! Their presence is enough to make most dogs and cats itchy and uncomfortable. Further, while a flea is “feeding” they inject a special saliva, and some pets have an allergic reaction to this saliva, making them VERY itchy. Vets will term this “flea allergy dermatitis” or “flea bite hypersensitivity”. Lastly, scratching and irritation will often lead to hair loss.  

How do I know if my pet has fleas? 

 Often you will be able to see the fleas on your pet. However, this is not always the case. Cats are excellent groomers and often get to the fleas before you can spot them. Sometimes, it only takes a single flea to trigger the “flea allergy”, making them hard to find! If you are worried, or unsure, don’t hesitate to contact your veterinarian.   

I’ve found a flea – what do I do now? 

 The most important thing to remember when dealing with fleas is that 5% live on an animal, and 95% are in the environment. Put simply, this means that if you find 5 fleas on your dog or cat, there are probably 95 fleas somewhere in the house or garden!  

  • If you have other pets in the house, treat them too! Remember, just because you haven’t found a flea on your other pets, this doesn’t mean they don’t have them. Treating all animals in the household is imperative to solving the problem quicker! 
  • Stay up to date with flea treatment! When your pet is due for his or her next flea treatment, it’s vital that you give it on time even if you can no longer see fleas. Remember, just one flea can trigger an allergic response!

And, of course, chat to your vet if the itchiness persists. Sometimes the itchiness leads to so much scratching that your pet develops a skin infection, which warrants a course of antibiotics. They may also advise you as to anti flea shampoos and anti-itch medications.
