The exterminator and bed bugs go hand in hand when you have an infestation problem. First make sure that you have a bedbug problem before calling the exterminator. If you see small dots all over the sides of your mattress that are moving around, then these are probably bedbugs and you should contact the exterminator.
The problem with sleeping on a bed with these pests is that they will bite you while you are sleeping and these bites might lead to an infection. The sooner you rid your bed of them the better.
Before the exterminator arrives, wash all the bedding and clothing in the vicinity of the mattress in hot water. Dry everything in the clothes dryer if you have one. Take out all the clothes and all other items from your closets because the exterminator will have to treat those areas.
Vacuum the rooms and clean up the floors where the bugs might be hiding. Pull all furniture and other items from the wall and place in the middle of the room. Then vacuum and clean along the walls that were covered by the furniture and other items. Pull drawers out from wooden furniture and empty the contents. The bugs can hide in the crevices of the wooden drawers.
The exterminator will spray insecticide in your home and even on your mattress. Wait until the mattress dries before using it and keep pets out of the room until it is safe to go back into the area. The insecticide could harm your skin.
There are many ways bedbugs enter homes. Sometimes they come in from hotel rooms. If you stay in a hotel room that has bedbugs, they can enter your luggage. You will unknowingly bring them home with you, so take precautions when traveling to check hotel rooms thoroughly before you decide to stay.
