Q. I have a blanket and a through and a sheet on my bed, do I have to dispose of them or could I clean them with something and save them?

A. You can wash the items in hot water in order to kill any bed bugs. The ideal temperature for treatment is about 113-115 degrees Fahrenheit.

Q. Resistance Unraveled

I read recently in a trade magazine that bed bugs are building up a tolerance to pyrethrins. How does this happen? If a bed bug is killed by a pyrethrin it's dead. How do the other bed bugs begin to build up a tolerance? How do bed bugs in another location build up a tolerance?

We can blame Natural Selection at the increasing resistance of a number of insects to pesticides. Biological traits and natural adaptation are the reasons why a number of weeds are resistant to some herbicides and some rodents still survive after digesting rodenticide-laden food or traps. The same can be said of people who seem to have better immune systems.

In the case of common, there are studies and proof that they have become resistant to synthetic pyrethroids. Synthetic pyrethroids are man-made version of pyrethrin and are made from petroleum derivatives. Pyrethrin, on the other hand, is an organic compound that attacks and paralyzes insects' nervous systems. Over the years, the insecticide industry has been dependent of synthetic products and in effect helping produce the next generation of bugs which are immune to its effects.

While pyrethrin is a better choice, there have been studies that showed cockroaches recovering from pyrethrin treatments. Recent insecticides that contain pyrethrin are now manufactured with one or two synergists for added efficacy. Other studies have shown that bed bugs have become immune to the deadly effects of dichlorodiphenyltrichloroethane (DDT), a water soluble insecticide. And since pyrethroids and DDT share some similar modes of action in attacking nervous systems of insects, a number of bugs are also considered immune to pyrethroids.

However, the concern of most people is the effect of synthetic pyrethroids, Are they still effective against insect infestation? Can synthetic pyrethroids create "super bugs"? The answer is yes and no. The bugs may look like they are adapting to the affects - some species are hardly taken down by the treatments, while others take longer or stronger doses to die. What we are seeing is the survival of the fittest, their genetic composition may have the capability to block certain effects of the insecticide. When these surviving bugs reproduce, their offspring are likewise resistant to the insecticide.

It travel by breeding and finding temporary shelter in clothing. From there they could set up shop in almost anywhere in the country. Their survival has always depended on moving and breeding in places that could give them the most ideal living conditions and food sources. Their ancestors have survived through this strategy and must have passed on genes that have better resistance on the effects of pyrethroids.

Dr. Mike Potter of the University of Kentucky said that some populations of the common bed bug have shown 1000x factor of resistance to synthetic pyrethroids. This means that the effect of the said compound is likely to have no effect of the target insects.
