Flea diseases

Generally speaking, the greatest discomfort resulting from the presence of fleas, is their bite and the intense itching that this causes. In most cases, the itchiness and red bite marks slowly disappear without any long term effects to your health.

However, because fleas are recognized disease and parasite vectors and can cause allergic reactions in more sensitive people or pets, it is important to know about the different possible diseases they can transmit.

If you think your home or property has a problem with fleas, contact your local Pest Control office today.



Diseases transmitted by fleas
In the U.S. the number of flea-borne disease cases is relatively minor. However, due to increased international travel and expected rising temperatures, diseases spread by flea species can now potentially affect more U.S. citizens than ever before.

Bubonic plague
The most well-known flea transmitted disease is the Bubonic plague. In the 14th century, the bubonic plague (known as the “Black Death”) became an epidemic and killed 25 million people - up to 50% of the European population.

Today, the plague still occurs worldwide, with only a handful of cases each year reported in the southwestern U.S. The plague is carried by rodents and transmitted to fleas that bite them, which is how it is transferred to humans and pets.

Thankfully, successful treatment can be achieved through the use of antibiotics.

Murine typhus
This is a rare disease in North America, but a few cases of Murine Typhus are reported each year and mostly originating in southwestern states. This disease occurs in rat-infested areas, where fleas become infected by rats.

The most common symptoms include high fever, severe headache, chills, weakness and nausea but treatment is available and patients often respond quickly.

Unfortunately, pets can bring plague or murine typhus-infected fleas into the home.

Tungiansis
This disease is rarely diagnosed in North America but due to international travel originating from tropical regions, like the West Indies, Caribbean, and Central America, where it is indigenous, it is worth knowing about this illness.

This disease is transmitted by the burrowing flea (Tunga penetrans), which is also commonly known as a chigger flea or sand flea (amongst others). It usually affects the feet, where the flea anchors itself into the skin and burrows into the epidermis. Travelers are often advised to wear shoes (not sandals) when walking across sandy areas in affected regions.

Tularemia
Tularemia is a potentially serious illness that occurs naturally in North America. It is caused by the bacterium Francisella tularensis and found in animals like rodents. It can be transferred to humans by an infected flea or tick bite.

Common symptoms include sudden fever, chills, diarrhea, joint pain and gradual weakness.

Tularemia is not infectious but medical attention is required to treat the illness and antibiotics are offered as treatment.

Bed Bugs and Disease

Bedbugs are small, oval, brownish insects that live on the blood of animals or humans. Adult bedbugs have flat bodies about the size of an apple seed. After feeding, however, their bodies swell and are a reddish color.

Bedbugs do not fly, but they can move quickly over floors, walls, and ceilings. Female bedbugs may lay hundreds of eggs, each of which is about the size of a speck of dust, over a lifetime.

Immature bedbugs, called nymphs, shed their skins five times before reaching maturity and require a meal of blood before each shedding. Under favorable conditions the bugs can develop fully in as little as a month and produce three or more generations per year.

Although they are a nuisance, they are not thought to transmit diseases.

Where Bed Bugs Hide

Bedbugs may enter your home undetected through luggage, clothing, used beds and couches, and other items. Their flattened bodies make it possible for them to fit into tiny spaces, about the width of a credit card. Bedbugs do not have nests like ants or bees, but tend to live in groups in hiding places. Their initial hiding places are typically in mattresses, box springs, bed frames, and headboards where they have easy access to people to bite in the night.

When considering bed bugs and disease, the prevalent medical position is they do carry disease organisms, but they are not known to transmit disease. While some sources claim that bed bugs are to blame for the spread of leprosy, Q-fever, oriental sores and brucellosis, these cases are poorly documented.

However, secondary infection may result if someone fails to keep the bites clean and disinfected, leading to swelling and bleeding of the bites. Infections are more likely to develop in children, those with suppressed immune systems and the elderly, especially those who are bedridden and unable to walk. Also, some people bitten by bed bugs have experienced allergic reactions that require medical attention, especially when exposed to numerous bites.

The greatest risk posed by bed bugs is the irritation of bites or the psychological concerns resulting in lack of sleep and stress. Bed bug bites do not typically become visible until a day or more after the insect's feeding, if at all, since some people never react to being bitten. In extreme reactions, large wheals can appear. These wheals gradually reduce in size, becoming small, red marks.

Bed bug bites can cause itching and may also result in swelling or blister-like skin inflammations. It is important to note that other non-bed-bug sources can result in skin irritations as well.

If you are experiencing bites or other skin reactions, contact a physician. If bed bugs are present in the home, a pest control professional should be contacted to eliminate them.
