While they once were thought to be under control, bed bugs have made a resurgence in recent years. This is due to several factors, such as increased travel, and the ban of DDT, one of the few pesticides that was effective against them. DDT was banned due to the serious health effects that were discovered, and now there are no effective ways to deal with the bugs.
One of the easiest ways to bring bed bugs into your home is when you are travelling. Many hotels are experiencing infestations, and they might not always be upfront with that information. A good habit when staying in a hotel room is to examine the seams of the bed and couch before using them or putting down your bags on them. Taking the sheets off your bed and inspecting the seam will let you get a clear view of any place where they might congregate. If you have an infestation in your home, remember that any failed attempt to kill bed bugs will just force them to spread out to new places, often making matters worse.
