Roaches in used sofa sleeper

Question: How likely is it that I will bring roaches into my home via a used sofa sleeper? I purchased it at Goodwill in Manchester, Mo. I have not yet brought it into the house. It is in my garage. I plan to keep it in the garage and set off a couple of bug killing bombs. Do you think this will ensure that we will not bring pests into our home? My zip code is 63043.

Answer: A good thorough cleaning will probably be all that is needed. Open the sleeper, shake out the mattress and vacuum the entire sofa.
