Pesticides Don't Work!
John Clark at the University of Massachusetts Amherst, among others, has conducted several experiments concerning resistance to many types of chemicals. The findings? A large sample of different pesticides were entirely ineffective in fully eradicating infestations. Part of the battle with bed bug infestations is finding and killing bed bug eggs. If eggs are not killed, the infestation will return. The self defense mechanism of the bed bug is to hide. Common hiding places for bed bugs can include INSIDE computers and electronics; are you prepared to spray your laptop with pesticides?
Heat is proven to work. Enzymes in the cellular makeup of the bed bugs and their eggs will die when exposed to heat of at least 118 degrees Farenheit. It is by far the best method for bed bug eradication.
