It is getting increasingly difficult to get rid of bed bugs around throughout the world. In some areas, it is much more difficult to get rid of these insects than in other parts of the world. Facing a problem withe these pests leads one to ask how to successfully get rid of bed bugs. Although DDT did kill bed bugs from the US earlier this century, now they are back and more able to resist our chemical attacks.
Studies of the genetics of bed bugs found in areas withe widespread outbreaks, by both the University of Massachusetts and Seoul National University have discovered very interesting developments in the bed bugs that reduce the effectiveness of thee common chemical treatments for the bugs.
Previous using other pyretheroid insecticides was how to get rid of bed bugs -one specifically known as deltametherin, have been used to treat thee condition of these pests. The chemicals are made to invade the nervous systems of the insect, and then successfully eliminating resulting in their death.
They appear to be developing immunity to thee poisons we are using to fight them. There is a porous surface on the outer membrane surrounding these neurons or nerve cells. The electrical nerve impulses were once thought to be produced in the pores are in fact produced in sodium channels. Pyrethroid toxins interrupt these kinds of nerve impulses, the use paralyzing and eventually eliminating the nasty critters.
Since they have evolved to be less sensitive to chemical pesticides commonly used, their neuronal pores no longer react to their toxins, and some, such as a population in New York City are now 264 times more resistant than non-mutated bedbugs to deltametherin, for example. This challenge has hampered the effects of discovering a successful method on how to get rid of bed bugs.
In effect, this particular bed bug treatment does not help eliminate the bugs; because the process which used to be over within minutes now lasts some days providing enough time and a conducive atmosphere for the bugs to multiply.
A population of the bed bug in Florida was also tested in an effort to see how far this mutation has spread. These bugs, having not been mutated, and are easier to get rid of bed bugs from an area than their mutated counterparts. In these mutated bugs the nervous system is insensitive to toxins and reveals bugs resistance in these further experiments was not due to being able to process the toxins more easily.
Sequenced genes which are straight linked to thee operation of sodium ion channels are found in the neurotoxin resistant of the pest and the same genes in other insects but not in, those bugs which are unmutated. This has been found by researchers using Molecular technology.
Although people view them withe horror, there are some natural treatments to rid your home of these life disrupting creatures, without exposing you to harmful chemicals, so do not despair. Today’s world there were many powders and sprays that are non-poisonous. Since bed bugs resistant to the usual chemical treatments are now widespread in the United States and other areas around the world, current research into new methods of how to get rid of bed bugs will be especially useful.
