Bed bugs are usually no more than 4 to 5 mm (1/8 to ¼-inch) in length in their adult state. They may cause itchy bites and can engorge themselves with human blood in less than 15 minutes — causing their bodies to fill to as much as three times their usual size. Bed bugs are a big problem in large cities and apartment buildings.
How bed bugs enter
The most common way a bed bug will enter your home is through international travel, or by travelling from a nearby infested unit. But you can also bring bedbugs home with you by being around someone else whose home is infested.
To identify bed bug infestations, look for the following: molted bed bug skins, fecal spots, or the bugs themselves along mattress seams, behind head boards, and along baseboards.
What to do to get rid of them
For effective control; launder all fabrics or let them heat up in the dryer for 1 hour on high. Vacuum the affected area thoroughly, dispose of the vacuum bag and spray your room with One Shot Bed Bug Killer and vacate for at least 15 minutes, and aerate before re-entering.
