Fleas are a stubborn pest that can affect any home or any dog at any point in time as long as the conditions are right for the fleas to thrive. Once you see one flea jumping or crawling on your dog or in your home, there will soon be hundreds making their way into your home. Although fleas are known to be quite difficult to remove, you can easily stop fleas in their tracks with the assistance of home remedies for fleas on dogs.


Fleas can be found in any home or yard, even if there are no pets present. This is due to the fact that fleas can lie dormant in carpets, grass, beddings, or other suitable environments until a ‘meal’ walks by and becomes the perfect host.

Fleas can be identified by their dark brown, near-microscopic appearance. Furthermore, fleas can and will jump from host to host, but contrary to popular belief, they cannot fly.

Fleas are highly resistant to freezing temperatures however they are most commonly seen in the summer months. The humidity and heat are attractive to the fleas because the warmth and moisture are optimal breeding conditions.

One important factor to understand in order to eradicate fleas is the life cycle of the flea. The life cycle of fleas occurs in four stages:

The life cycle of fleas

  • Egg
  • Larvae or Caterpillar
  • Pupa or Cacoon
  • Adult

The amount of time it takes for a life cycle to complete depends on the environment as well as available hosts. If all conditions are right, a cycle can be completed within two weeks.

The cycle starts when an adult female begins to lay her eggs. She will lay eggs on the host and will lay eggs up to three times each day with twenty to thirty eggs in each layer. While the adult female is laying her eggs, she will feed on the host by biting them and sucking the blood. Over the entire life span of a single adult female flea, several hundred eggs will be laid. The sheer amount of eggs produced is one of the main causes of flea infestations.

Once the eggs have been laid, they will begin to develop on that spot. First, they will hatch into the larvae and begin to feed on whatever suitable food source is nearby. This includes dead skin cells, organic matter, and/or the blood-rich feces of adult fleas.

The third stage of the life cycle is when the larvae will form a cocoon to pupate. This part of the cycle will occur after the larvae have molted two times. Once the adolescent fleas are in their cocoons, they will remain there until the environmental conditions are just right. The cocoons can sense carbon dioxide exhales, vibrations, as well as warm temperatures. These are all signs that a host is nearby and the combination of the three will trigger the emerging of adult fleas.

The newly hatched adult fleas can jump onto a host right away. This will further induce the flea life cycle which is another reason why fleas are such stubborn pests. Due to the tenacity of this parasite, it is vital to use more than one home remedy for dog fleas to fully break the cycle, kill any existing fleas and eggs, as well as prevent the fleas from ever returning.

Signs and Symptoms

There are several things you can easily identify that are sure signs of fleas. 

  • Intense, almost non-stop itching
  • Redness of the skin
  • Hair loss (most especially in the base of the tail or near the rump)
  • Scabs
  • Irritated skin
  • Dry skin
  • Dried blood in the fur or on the skin
  • Flea dirt (This is one of the first major signs of fleas. Flea dirt is the blood-filled feces of any present adult fleas. The small, dark spots will appear to be like specks of dirt or coffee grounds and are usually found at the base of the tail.)
  • Development of hotspots
  • Development of flea allergy dermatitis

It is also important to realize that fleas will bite humans as well. If you notice that you have any of the following symptoms, there are most definitely fleas present in the home and/or on your dog. Signs and symptoms of flea bites in humans are:

Signs & symptoms of flea bites in humans are:

More often than not, dog owners whose precious pooch is suffering from fleas will also show signs and symptoms that fleas are present. Since fleas can be such a nuisance and a stubborn parasite to remove, it is important to seek multiple treatments right away. This will help you break the life cycle and ease your dog’s symptoms.
