Bed Bugs Can Transmit Parasite That Causes Chagas Disease Sciencedaily

Reduce clutter around the room to eliminate places where the pests may hide, and caulk or seal all holes and cracks. If someone suspects a bedbug infestation, try to detect and confirm their presence. Rarely, in cases of a severe systemic allergic reaction, injections of epinephrine, antihistamines, and corticosteroids may be required. Resistance of Cimex lectularius and Cimex hemipterus tosynthetic pyrethroids is now widespread worldwide.

Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person. Bedbugs should be exterminated using physical and, usually, chemical methods. Physical methods include vacuuming infested areas and washing articles of clothing or bed linens, then drying them on the dryer’s hottest setting.

The typical skin lesion is a pruritic erythematous maculopapule, 5 mm to 2 cm in diameter, with a central hemorrhagic crust or vesicle at the bite site, similar to arthropod bites. Atypical forms vary from asymptomatic or pauci-symptomatic to purpuric, vesicular, and bullous lesions. The bedbug-bite distribution frequently follows a line or curve . Lesion numbers range from several to many, depending on habitat-infestation intensity, and are preferentially located in unclothed zones .

Their mouth has evolved in such a way that allows bed bugs to easily pierce skin without causing pain to humans. Bed bugs have been a human pest since prehistoric times, but during the last century they were controlled quite effectively with household insecticides. However, a very strong resurgence of bed bug infestations in human dwellings has taken place beginning in the 1990’s. This resurgence seems to be related to the spreading of bug populations resistant to synthetic pyrethroids, the pesticides most commonly used against them. Many developed countries, including the U.S., where the bugs seemed for years to have been a thing of the past, are now having to contend with them once more. Although паразитни дървеници have been unwelcome companions of people since ancient times, as their numbers dropped drastically in the 1940s and ‘50s , so did American’s knowledge and vigilance regarding these pests.

The parasites are hidden mainly in the heart and digestive muscle, and over time can cause cardiac disorders and sometimes digestive or neurological problems. In later years, the infection can lead to sudden death or heart failure caused by progressive destruction of the heart muscle. Although there are some drugs to treat Chagas disease, they become less effective the longer a person is infected.

Potential shelters are whatever hollow places in equipment (tubing, fencing, feeders.) or buildings (hollow floors and ceilings, cracks and crevices, etc.) where bugs hide and congregate during the day. The birds are stressed and develop skin inflammations, particularly in the breast and the legs. Massive infections can cause anemia due to excessive blood loss. Bug feces leave small spots on the eggs that can reduce their value. Development stops at temperatures below 13°C, but the bugs can survive temperatures up to -10°C.

Once in our homes, these pests are hard and expensive to control and eradicate. Thus, preventing their introduction into your home is increasingly important. Local antiseptic lotions or antibiotic creams can be applied for secondary infections, whereas corticosteroid creams and oral antihistamines can be used for allergic reactions.
