My brother is an exterminator, he has always loved his job. Having said that the bed bugs are ruining it for him. They are tough to find,.and hard to treat. As someone already said they have taken the chemicals away that did a great job. Something else to think about is all the college kids come. YIKES! Also where you live or how clean your house is has NOTHING to do as to whether you might get bed bugs. They don't discriminate the love everyone.
