Bed Bugs May Be Splitting Into New Species
As a built in hazard of living cities, bed-bugs are parasites that love an interminable food option, lively crowds, expedient transportation and the comfort of our houses and homes. By nature they are stow-away, hide during the day and feed at night. As blood feeders, the presence of bedbugs in any home has very little to do with the general cleanness though clutters can provide a very ideal hiding places for these pests. In addition bed bugs can be very difficult to control, even for the highly trained and skilled exterminators.
There are various ways that can be used to effectively kill bed bugs with the most common one being the use of pesticides. But none the less most of these pesticides are not very effective especially in killing eggs and that is why a repeat of the treatment is usually prudent.
In addition, there are different types of pesticides that are used for controlling bedbugs that are available in the market today, with most of them being lethal for human beings and animals, and has caused a number of deaths. One such substance is Phosphine.
When used as a pest control substance, Phosphine which is usually a gas in its natural form is usually sold in powder form and is usually combined with either aluminum or calcium tablets. When added to water, in a very humid environment, phosphine gas is released, which is very toxic to both humans and animals.
Evolution of Bed Bugs
It enters the human body through the lungs, and then into the body tissue. What makes phosphine gas lethal is its ability to damage the cell by affecting the ability of the cell to produce energy.
In addition scientists have recently found some new genetic hints that could explain why bedbugs have recently become so hard to kill. According to a journal by a team from Ohio State University, they indicated that some bed bugs appear to have evolved some form of mechanisms that assist them to break down toxins especially the ones that are used in pesticides.
These findings comes after an earlier research found out, that the genetic changes in bed bugs assists them in protecting their nerve cells from specific pesticides. Both of
the findings definitely suggests that current efforts to curb bed bug infestations will be very difficult than in the past.

The most recent explanation for the bedbugs in built ability to resist pesticides, was developed from a study that was comparing genes from the modern bedbug and those that had been contrived by a military bug expert, decades ago.
When exposed to insecticides, the pool that had been isolated died instantly. This in turn indicates that the enzymes levels are much higher in a pesticide exposed population in comparison to the pesticide predisposed population.
The bed bugs ability to protect nerve cells and eliminate toxins has become very common. Most of the bedbugs nowadays have become more resistant to pesticides and the level of resistance to these substances is quite extra ordinary.
What is the ideal way to kill bedbugs?
According to the team at Ohio State University, the new information about resistance and the latest bed bug news suggests the espousal of a different approach to kill bedbugs. Instead of banking on the same type on insecticides generation after generation, a different class of insecticide or pyrethroid, needs to be used in rotation with a different class of actions.
The bedbug control should also include non-chemical approaches like vacuuming to eliminate them from a room or the use of heat, instead of relying on one chemical approach after the other.
