We had an excellent pest control guy. So he told us exactly what to do (wash EVERY surface - floors, doorframes, doors, and baseboards - with a mix of water, bleach, and Pinesol). As well as a timeline of how many days we could expect to continue to see dead bugs. So a lot of effort ... it took about an hour and a half to clean each room. Followed by two hours in the massage chair to prevent my back from seizing up. But a very clear roadmap. It made us feel in control. Plus, my husband was in charge of picking up and flushing dead bugs. :-)
