Experts believe that the increased incidences of bed bug infestations are due to several things. Some believe that it is due to the ease of foreign travel, decreases in the countermeasures that homeowners are taking to prevent an invasion, and an increase in the use of second-hand furniture and clothing. The worst part is that the longer your infestation continues the more expensive and difficult the process of extermination becomes. That is why preventing the infestation to begin with is the best answer to this potential problem. The way to assist in doing that is to get a mattress cover for all the beds in your home.
