Bed bugs thrive in places where large numbers of warm blooded animals sleep. For this reason the parasites, which live on a diet of blood from animals and birds exclusively, are more common in hotels, motels and apartment buildings than they are in private homes and more likely to be found in urban areas that in the countryside.
The fifty years between the early 1940s and the late 1980s were the first time in history that a substantial portion of the human population lived without sharing its bed with the bed bug. Prior to the use of DDT, bed bugs were a common nuisance throughout human history. Widespread use of DDT spray to control pest populations in the 1930s and 1940s were believed to have exterminated bed bugs from essentially all of the continental United States by the end of World War II.
Beginning in the late 1990s, North American health officials noticed a rise in reported cases of bed bug infestation. Some of these reports came from health and housing agency data, but the most data-rich information was from the trade industry associations of the pest-control industry. The speed of the outbreak has increased dramatically over the past five years.
It is believed that there are a number of factors behind this new epidemic of bed bugs. The increase in international travel has been cited as one possible cause. Another widely cited contributory factor is new methods of pest-control. In the 1990s fumigators began to use bait to control cockroaches rather than pesticide sprays. The bait introduced poisons into the colonies. This process was found to be more effective and less intrusive than spraying and the use of insecticidal and other sprays was reduced to almost nil.
It has been noted that the epidemic occurs in epicenters. It has been reported that poultry farm and processing factories were at the center of geographic outbreaks in Texas, Delaware and Arkansas. A rate of infestation in the homes of the poultry workers indicated that the workers were becoming infested by a bed bug epidemic in the poultry.
While data for be dug cases in Mexico are unavailable, it is know that cases reported in the rest of North America have increased throughout the first decade of the new century. Outbreaks in large urban areas like Toronto, Canada, and New York City are of particular concern and proving particularly difficult to reign in.
Bedbugs have developed massive immunities to two of the most used chemical families of pesticides: pyrethroids and deltamethrin. A study of bed bugs from randomly selected areas around the continent was conducted by the University of Kentucky. It found that the insects were more resistant to pyrethroids by a factor of thousand compare to bed bug kill data in tests from the 1970s.
Bed bugs get around in the clothing and on the person and lodge in beds and furniture. Pets and children can become carriers if they get into the nest or boroughs of warm-blooded animals, where bed bugs are present. Travel in areas where bed bugs are prevalent frequently results in the bug returning home with traveler.
The 21st century plague of bedbugs in the U. S. Led the Environmental Protection Agency to call a summit on the issue in the spring of 2010.

Shows the making of a simple trap to catch water bugs and other things. Catch fish as well as crayfish, yabbies, shrimp, minnow, worms, leeches, snails from river, swamp or dam for fun, study or fishing bait. plastic bottle light trap.
This trap I had initially “invented” to help with a university assignment that required the capture and classification of a range of fauna, worked very well.
