Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals. Cimex lectularius only feeds every five to seven days, which suggests that it does not spend the majority of its life searching for a host. When a bed bug is starved, it leaves its shelter and searches for a host. It returns to its shelter after successful feeding or if it encounters exposure to light. Cimex lectularius aggregate under all life stages and mating conditions. Bed bugs may choose to aggregate because of predation, resistance to desiccation, and more opportunities to find a mate. Airborne pheromones are responsible for aggregations.
Bed bugs were first mentioned in Germany in the 11th century, in France in the 13th century, and in England in 1583, though they remained rare in England until 1670. Some in the 18th century believed bed bugs had been brought to London with supplies of wood to rebuild the city after the Great Fire of London (1666). Giovanni Antonio Scopoli noted their presence in Carniola (roughly equivalent to present-day Slovenia) in the 18th century.
Some people have no reaction whatsoever to bed bugs. In addition to not having much of an effect on the elderly, some are just not allergic. Since the irritation and welting appears as the result of an allergic reaction, it is possible to not even know that you were bitten at all. It is entirely possible for several people to live in the same house, and have one person not be affected.
I moved into my apt in April and started getting bitten in June , my apt have been professionally treated 3 separate times. I have a 3 year old and I’m so worried for her she doesn’t seem to get bitten or if she is she doesn’t have the bad reaction that I do which is good. I have 18 bites in the past week the worst I’ve ever had. I can’t find the little blood suckers but I found a bed bug spray at home depot. I’m going to treat my house wash and dry all my clothes in hot temps , then caulk every crack and crevice in this apt. I plan to do this every week until my lease is up and I can move out this apt 7 more months.
Found worldwide, bedbugs are most common in developing countries. Still, reports of bedbugs in luxury hotels are not uncommon. They are most commonly found in areas like hostels, hotels, shelters, and apartment complexes where there are many visitors coming and going. When they enter your home, it's often because they have hidden in luggage, furniture, clothing, or boxes that are being moved. They can also travel on pets' fur. Increases in international travel may be responsible for the rise in bedbug sightings.
While cleaning up infested areas will be helpful in controlling bedbugs, getting rid of them usually requires chemical treatments. Because treating your bed and bedroom with insecticides can be harmful, it is important to use products that can be used safely in bedrooms. Do not treat mattresses and bedding unless the label specifically says you can use them on bedding.
