If you have an insect infestation and have hired an exterminator to take care of the problem, you should prepare your home first. Taking these steps will help the exterminator so that his visit is as short as possible and his work is effective. That means a lower bill for you and a decreased likelihood of another bug invasion.
The steps you'll need to take depend on the kind of infestation you're experiencing. Cockroaches require kitchen preparation; bedbugs need to be dealt with in bedrooms.

Remove items from the affected areas. In kitchens, you'll need to remove everything from the cupboards and counters, including contact paper from the shelves. For bedbugs, remove and launder all linens and clothing from the bedroom and living areas. Store cleaned items in plastic bags to prevent bugs from returning to them. Empty dressers, nightstands and bookshelves and remove drawers. Unplug any appliances.
Clean the areas to be treated. Vacuum carpets, window coverings, furniture and cupboards; sweep and mop floors. If you have access to a steam cleaner, steam-clean floors, carpets, drapes and upholstered furniture in the affected rooms.
Move any furniture placed along walls toward the center of the room and clean behind it.
