Are Fleas Harmful To Humans?

Below are some of the distinct ways by which cat fleas can cause trouble in the body.

  • Plague: Fleas host bacteria called Yersinia pestis, which can contaminate cats. This is mostly derived from consumption of infected rodents or from rodent fleas that get transported to cats. Such fleas tend to bite human beings and pass on the disease when they’re brought inside the home.
  • Murine Typhus: This is formed by a bacterium transported by infected fleas via rodents to humans or cats. It is acquired from bites by infected fleas when your cat comes in touch with their feces. The symptoms are nausea, vomiting, abdominal pain, and an exceedingly high fever, which lasts for more than a week. This is rarely incurable and is more common in the summer months.
  • Allergic Reactions: Reactions from flea droppings and flea bites are very common caused by cat fleas biting people. These flea bites occur often on the ankles, legs, and feet and cause itchy, red welts. Symptoms of allergic reactions like extensive itching, swelling, and hives can be cured with treatment, depending on the reaction severity.
  • Tapeworms: These can be transmitted to you if fleas are ingested accidentally. Tapeworm infection symptoms are often similar to that of other diseases, such as appetite loss, mysterious weight loss, weakness, nausea, and diarrhea. Prescription medication can be required to relieve the human body of the tapeworms. Fortunately, these flea bites do not transmit. If your cat is infected with worms, try these cat dewormers for best results.

What Are The Symptoms Of Cat Flea Infestation?

Fleas are minute insects that feed and bite on a pet’s blood. The bites are uncomfortable and can pass grave ailments into the bloodstream. If the flea problem has been persistent in your cat for long, they can be visible too. They’re generally dark brown or lighter. Symptoms are:

  • Extreme scratching, particularly around the ears.
  • Undue licking.
  • Bump sand redness on the skin.
  • Restlessness.

What Is A Flea Collar?

Flea collars generally hold insecticide drugs that are gradually absorbed into your cat’s skin. This insecticide spreads out from the neck region to whole of the body. A flea is poisoned and dies by this insecticide after biting.

Different flea collars brands make use of different insecticide types. Some are helpful against ticks as well. The employment of cat flea collars is one of the very popular and easy to get flea management option. If you come in contact with a flea collar, it is prudent that you wash the hands immediately after.

How Do Flea Collars Work For Cats?

The flea collars designs differ depending on their insecticide formulation. There are 2 main types –liquid and solid.

  • Liquid: The fluid insecticide preparation discharges as gas, for repelling the existing fleas, but doesn’t kill them. This method can be very ineffective as only fleas, which are close to the flea collar will get affected.
  • Solid: In case of solid types, resin and insecticide are blended so that the insecticide discharges in due course from rubbing against the cat’s fur and skin. It may either disperse across the cat’s skin or absorb into its top layers, depending on the particular insecticide used. For the dispersion type, it only requires the flea to get into contact with the insecticide for it to take effect. For the absorption type, the flea needs to bite the skin. This way is more safe and efficient to use. Although you require a prescription from the vet doctor for using it.

One factor that can diminish the efficacy of a collar is wetting it numerous times a week. Most of these collars are scheduled as “waterproof”. A monthly bath can be passable, yet too many of them can wear off the insecticide.

It is important to pay due attention to the products labels to verify if they are operative on killing eggs, larvae, adults, and pupae. The products that have “Repels fleas” written on them are most likely not effective in eliminating the existing fleas. Above all, no matter what cat flea collar kind you are planning to buy for your pet, make sure that it is 100% free of chemicals.
