Can flea dirt be dangerous?

For Dogs

The presence of flea dirt simply tells us that your pet’s body has fleas and that you need to do something about it. The quantity of flea dirt matters, if you find a lot of flea dirt then chances are that your dog or cat has fleas and needs to be treated immediately. The fleas could have also laid eggs on your pet as well as around the house. When this happens your pet might have itchy skin (which is quite normal) and excessive itching can cause scars on their skin as well.

Moreover, many types of fleas carry diseases that can cause skin problems or allergies to your pet. Some cases of anemia have also emerged because the larvas use the pet’s blood as food to thrive. Although this is quite a rare scenario, if there are too many flea bites and flea dirt on your pet, make sure you consult a vet.

However, flea dirt is usually harmless to your pet but that doesn’t mean it should be taken lightly.

For Humans

While only pets are victims of flea dirt, it can cause problems for humans as well. If your pet has flea dirt then there is a chance that infection can spread around the house if not taken care of. However, to cause notable problems within the human body, a person should have consumed a flea or been bitten by it to stimulate the transfer of pathogens.

Other than this, washing your hands every time you handle a pet is a great habit and can prevent you from unwanted diseases.
