Fleas: An In-Depth exploration of the most annoying creatures on earth


Fleas are small, wingless insects that are DEFINITELY one of the most annoying creatures on earth. They are experts at jumping (up to 200 times their own body length!) and are known for their ability to transmit diseases to both humans and animals.

Fleas are also very good at reproducing. A single female can lay up to 50 eggs per day and can live for several months. In just a short period of time, a flea infestation can quickly get out of control.

While fleas are most commonly associated with dogs and cats, they can also infest houses. Fleas are attracted to warm climates and are most active during the summer months. However, they can also survive in cooler climates and will become more active in the winter if given the opportunity.

In this article, we will explore everything you need to know about fleas – from their biology to the best ways to get rid of them.

What are fleas?

Fleas are small (3 mm long) insects that belong to the family of Siphonaptera. They have long, flat bodies and are equipped with long, spiky legs for jumping. Fleas feed on blood from their hosts and are known as pests because of their ability to transmit diseases. Fleas have four stages in their life cycle: egg, larva, pupa and adult. Each stage can last anywhere from two weeks to several months, the length depending on the temperature and humidity of the environment. Adult fleas can live up to 100 days and female fleas typically lay five eggs per day. Fleas are most famously known for their ability to jump long distances – up to 200 times their own body length! They also crawl quickly and can quickly multiply. All of this makes them one of the most annoying and destructive pests on earth.

A flea’s life cycle

Fleas go through four stages of development before they reach adulthood. These stages include egg, larva, pupa and adult. Each stage can take anywhere from a few days to several months, depending on the conditions. The egg stage is the first stage and lasts for 1-2 weeks. During this stage, female fleas lay eggs on their host – usually the pet or person’s skin. The eggs then hatch into larvae and start to feed on organic matter such as flea feces and dead skin. The larvae will go through three molts before entering the pupa stage. During this time, the larvae will build a silken cocoon around itself and remain protected for 2-3 weeks before emerging as an adult flea. The pupa stage is the final stage before adulthood and is the stage where fleas are most vulnerable to pesticides and other treatments.

The impact of fleas on animals

Fleas feed on the blood of their hosts, usually a mammal like a dog or cat. They can quickly become a nuisance and cause skin irritation, infection and a decrease in general health. Fleas also have the potential to spread diseases like bartonellosis, haemobartonellosis and even typhus. Fleas can be extremely hard to get rid of. A single flea can lay up to 50 eggs a day and can live for several months. This makes them extremely difficult to eliminate, especially if not tackled immediately.

The impact of fleas on humans

Fleas can also directly and indirectly impact humans. Directly, fleas can bite humans and cause itching, skin irritation, and even disease if the flea is carrying infectious organisms. Indirectly, fleas can cause an infestation in the home, which can lead to an increase in dust mites and other unwanted creatures. Fleas, although small, can also cause an increase in allergies due to the proteins found in the flea’s saliva and excrement. People can even develop an allergy to the flea’s saliva, resulting in an increase in itching and discomfort.

How to get rid of fleas

The best way to get rid of fleas is to contact pest control experts. These experts will be able to properly identify the infestation and develop a plan to effectively eliminate the fleas. In addition to contacting pest control experts, home and pet owners can also treat their premises and animals themselves. This can be done by vacuuming the premises to remove any eggs or larvae and using flea treatments on the pet’s skin and fur. This should be done in conjunction with a reputable carpet cleaning company in Liverpool like Eco-steam clean Liverpool Ltd, our steam generator can reach temperatures as high as 230c, 218c is the required heat to eliminate fleas so we have plenty of room for manoeuvre.
