The affordability of air travel has made it easy to reach almost anywhere in the world quickly and cheaply. And attitudes toward pesticides have changed, Barbarin notes. Routine pesticide spraying became less frequent, as people became wary of its large-scale environmental effects.
Rachel Carson's Silent Spring is often credited with this change in public consciousness. While today many consumers want "green" pest-control solutions, in a former era, Barbarin says, powerful pesticides such as DDT would have been on the front lines fighting bed bugs.
While some experts suggest bringing it back, Barbarin notes that bed bugs had shown resistance to the chemical as early as Another class of pesticides, called pyrethroids , has largely replaced DDT—but bed bugs have also shown resistance to these compounds. The only solution to the pesticide-resistance problem, Barbarin says, is more research and more public education.
In this case, adds, using a biological control is not really an option. Talk about a Catch —one of the bed bug's fiercest natural enemies is the cockroach. These allergic symptoms can include enlarged bite marks, painful swellings at the bite site, and, on rare occasions, anaphylaxis.
Bed bugs are experts at hiding. Their slim flat bodies allow them to fit into the smallest of spaces and stay there for long periods of time, even without a blood meal. Bed bugs are usually transported from place to place as people travel. The bed bugs travel in the seams and folds of luggage, overnight bags, folded clothes, bedding, furniture, and anywhere else where they can hide.
Most people do not realize they are transporting stow-away bed bugs as they travel from location to location, infecting areas as they travel. Everyone is at risk for getting bed bugs when visiting an infected area.
However, anyone who travels frequently and shares living and sleeping quarters where other people have previously slept has a higher risk of being bitten and or spreading a bed bug infestation. Bed bug bites usually do not pose a serious medical threat. The best way to treat a bite is to avoid scratching the area and apply antiseptic creams or lotions and take an antihistamine.
